Many industries are familiar with the beneficial effects of various hard chrome, nickel, TiN and PTFE plating products. Unfortunately, most of these plating products have definite limitations in a variety of application requirements.
The Electrolizing® Coating Technology, as provided by Electrolizing®, Providence, RI, coatings meet and exceed the demands of industry today. Electrolizing®'s technologically advanced surface coatings provide solutions to an engineer's five most critical problems:
Lubricity Corrosion Adhesion Precision Hardness
A combination of our proprietary metal surface preparations and advanced coating processes result in unsurpassed and consistently reliable coating applications.
Electrolizing, Inc is housed in a clean, modern 24,000 sq. ft. building.
Electrolizing®, Inc. has been tested and is certified compliant with all Federal and State air and water regulations. We are proud to have been awarded the 1996 Rhode Island Environmental Merit Award for "Outstanding Pollution Prevention."
Electrolizing®, of Providence, RI offers three premier coatings to meet the demands of even the most difficult applications: the Electrolize® coating, our flagship product, Micro-E for the most precise application requirements and Al-Coat, for coating aluminum alloys. Each coating contains the highest quality chromium, which produces consistently controlled deposits in any application.
The Electrolizing® coating technology was developed in 1945 in Providence, RI. For over 50 years, Electrolizing®, Inc. has consistently refined our process to keep it the most advanced ultra-pure, versatile chrome coating available in the market. Electrolizing® continues to be the leading coating technology for all industries.
The Electrolizing® coating is a proprietary blend of pure chromium that produces a very hard surface measuring 70-72 on the Rockwell C scale. The coating is applied at a temperature below 180oF. This "cold" process protects precision-machined parts from hydrogen embrittlement, distortion, annealing, and from changes in the base metal’s tensile, fatigue and microstructure properties.
Engineered coating deposits can be applied from .000050" to .001" per surface according to customer specifications. Precision tolerance requirements can be engineered for any deposit thickness.
The Electrolizing® coating is a smooth, fine-grained surface. The Electrolizing® coating will be free of blisters, nodules, porosity and excessive edge build-up.
Please contact an Electrolizing Applications Engineer for more detailed information about the Electrolizing® Coating Technology.
For over 50 years, Electrolizing®, Inc., of Providence, Rhode Island has provided the highest quality state-of-the-art coating technology to the industrial world. Our coating technology has been developed and refined over the years giving Electrolizing® coatings a distinct advantage in the marketplace. As a result, there is no comparison that can be made with conventional plating products.
Electrolizing® coatings are made from the highest quality materials available and are regularly monitored to ensure compliance with our proprietary standards. This emphasis on quality control combined with our highly trained, experienced staff, results in premiere-quality, uniform deposits in every application.
Electrolizing® Inc. is compliant to ISO standards. All processing steps, quality measures and maintenance procedures are documented and available for review for each application. Our Quality Assurance staff can provide precise measurements of deposit thickness by using the latest advances in fluorescent x-ray technology, laser micrometers and many other state of the art instruments..
Lubricity
Recognized as the "benchmark" of providing beneficial coefficient of friction properties, PTFE is the polymer of reference. Since both Micro-E and Electrolizing are metallic coatings, comparison should be made to which application provides both initial frictional benefits, as well as long-term frictional benefits.
Electrolizing coatings are excellent for providing a "dry lubricant" surface. When discussing "steel against steel", the resultant frictional values range to about .20 or greater. Micro-E and Electrolizing provide the user with .09 to .12 values, or approximately 50% improvement. Lubricated conditions will result in even lower values.
Corrosion back to top
The Electrolizing products have been subjected to corrosion testing using ASTM-B-117 salt spray procedures. The results meet or exceed the criteria stated in the specifications QQ-C-320, AMS 2406 and AMS 2438. In addition, the coatings have been evaluated in humidity tests, salt water, de-ionized water, bleaches, copper-sulfate, mold cleaners and various commercial reagents, acids, alkalines and salts. Electrolizing coatings are accepted for use in USDA environments.
Adhesion back to top
Adhesion is the most important focus of the Electrolizing technology. Without adhesion, neither metallic or polymer-type plating have any benefits. The Electrolizing coatings must meet our standard repeated bend testing to 180o degrees without showing signs of chipping, spalling off or separation. The results of our adhesion testing enables our technology to meet the standard ASTM-B-489-85.
The Electrolizing technology also focuses on the "cohesive" properties of the molecular elements being applied, and assures that these molecules form an absolute cohesive bond to themselves. This application technology does not allow Electrolizing to "peel-off" in layers or shed loose particles of itself.
Precision back to top
The coatings provided by Electrolizing were developed and designed to be precise, thin depositions. The ranges of normal coating thickness requirements are from 0.000050" to 0.001" per side. Thickness requirements per part vary by material, engineering application and expected performance criteria.
The procedures, controls and techniques for applying Electrolizing assure that highly precise tolerances can be maintained. Tolerances, as precise as 0.000050" to 0.0001" are routine. Tolerances vary with thickness and part geometry.
The availability of a thin, precisely controlled Electrolizing coating can eliminate the need for traditional hard chrome plate and grind. These procedures lend themselves to expensive grinding, rework and handling demands.
Hardness back to top
Electrolizing provides the metal with a surface hardness of Rc 72 Rockwell. A combination of factors enable the coating to achieve such a tough and extremely hard surface. Electrolizing combines appropriate engineering of proprietary alloys and pure chromium, with a consistent, controlled and unique deposition processing procedure. The density of the coating provides a surface which has less cracks, inclusions, voids and other surface irregularities as compared to conventional chrome platings. The combination of hardness and density results in reduced wear rates and material fragmentation.
Micro-ETM coating is an engineering extension of the Electrolizing® coating. Micro-ETM incorporates a multi-step cleaning process along with modified coating application techniques that results in a harder (75 Rc) surface finish.
The target deposit thickness of the Micro-ETM coating is specified from .000050" to .0003" per surface, depending on customer requirements. This thin, precise deposit eliminates dimension changes, distortion of the parts and also eliminates edge-build problems.
Micro-ETM orders receive preferred handling, inspection and processing procedures performed by certified technicians. The latest advancements in inspection equipment are used including fluorescent x-ray and laser micrometers.
If you are looking for new technology, or are involved in one of the more leading edge industries, consider Micro-ETM for your coating needs.
Al-CoatTM was developed to meet the challenge of protection for ALL aluminum alloys. This technologically advanced coating provides a precision deposit of a dense, non-magnetic, high chromium alloy deposited directly on the aluminum substrate.
Most conventional electroplatings and/or conversion coatings find aluminum alloys extremely difficult to coat for the following three reasons:
* Aluminum oxidizes rapidly.
* Aluminum acts as a cathode during the coating process leaving voids in the coating which lead to corrosion problems.
* The thermal expansion seen with aluminum alloys differs markedly from most metals used in electroplating. This factor causes most conventional plating products to peel, chip, flake and not adhere to the base aluminium substrate.
Al-CoatTM offers an extremely hard (70-72 Rc) surface providing an unusual combination of bearing-type properties, low friction coefficients, longer wear life and excellent corrision protection. Deposit thickness for most applications can be engineered up to .001" per side. The coating WILL NOT chip, flake or peel in application.
Al-CoatTM is non-reflective, matte satin-gray coating. It is uniform in deposit thickness and consistent in appearance, eliminating staining and discoloration problems.
Al-CoatTM has been proven successful in many different applications including:
Sizing Dies and Molds
Heat Sealing
Medical Equipment
Aircraft Housings and Shafts
Automation Equipment (Plates, Rails, Slides)
Computer Chip / Wafer Processing
Test Equipment
Al-CoatTM meets specification QQ-C-320, AMS-2438 and is USDA compliant.
