Achrolytes

Achrolyte is a 1975 by the American Oxy Metal Industries Corporation deposited trademark for a electrochemical method which has a tin - cobalt - alloy is deposited and the chromium plating is so far very similar, can hardly be distinguished as the coating properties thereof.

properties

The tin-cobalt coating is characterized by a uniform and optically sophisticated surface. The extremely thin, approx. 0.2 micrometer thick and nonetheless characterized by high abrasion resistance, consists of an average of three quarters of galvanically deposited tin and the remainder of cobalt that is also produced.

The properties of their components, e.g. B. good chemical resistance , are included in the alloy, because cobalt is harder and stronger than steel. The alloy can only be dissolved by very strong acids.

application

The achrolyte process is mainly used when chrome plating is not possible or disproportionately expensive, or to avoid toxic chrome baths.

Tin-cobalt coatings are highly suitable for decorative applications and within the limits of the earth have barrel plating , as well as means of conserving rack plating are applied. The gloss of the layer depends on the surface texture of the base material and the recommended intermediate nickel layer (3–10 μm).
