What is Electralloy?
Electro-Coatings' exclusive hard chrome plating process called Electralloy™, delivers a highly corrosion, wear and friction resistant industrial chrome surface without component distortion and coating inconsistencies of traditional chrome plating. It can be applied to a wide variety of substrates and geometries.
Chrome Plating Advantages
Electralloy is an industrial chrome layer deposed in a microscopically thin coating from 0.000025" to 0.0005" in depth, a density which will not materially change the micro inch value of the base metal. The chrome electroplating process produces an exceptional hardness and a high level of surface consistency, providing a coefficient of friction 40% lower than lubricated steel (.12 to .13 vs, steel at .20). The result is a marked reduction in abrasion, erosion, adhesive wear, scuffing or galling, scoring and seizing.
As an added bonus, hard chrome or industrial chrome plated parts are far more corrosion resistant than standard chrome plated parts. The surface inconsistencies that are a by-product of standard plating do not occur with the dense chromium composition and microscopic thickness of Electralloy coating. This attribute offers significant cost savings by allowing the substitution of low cost base metal for expensive corrosion resistant steels. Electralloy maintains its anti-corrosion protection across a wide temperature range, yielding consistent friction reduction without degradation by extreme heat or cold.
Industry Standards of Hard Chrome Plating
Hard Chrome Plating Process & Specifictions
Generally, hard chrome plating includes several stages: stripping to degrease the metal and remove all traces of dirt, soil and other impurities; various pretreatments, including polishing and sanding; wiring and racking to hold parts in the plating tanks; and, finally, placement into a plating tank and application of plating current. There are variations to the process depending on the type of substrate.
- Fights friction without changing component dimensions
- Surface hardness to 70 Rockwell C
- Low coefficient of friction (0.12 to 0.13 against lubricated steel)
- Low heat application won't distort components
- Higher resistance to corrosion than standard chrome plating
- Performs in temperatures from -425° to +1150° F
Exceptional Application Skill
As with any thin dense chrome coating, successful Electralloy application relies on careful fixturing of parts and precise control of the plating bath. The plating craftsmen at Electro-Coatings have extensive experience at this critical process, and are solidly backed by the latest in costing technology and the engineering expertise of seasoned experts in the plating, coating and metallurgy fields.
