The reason why hard chrome plating is used is not only that it produces a hard layer. Studies carried out by industry and research institutions show that the required properties are not only hardness but also sandability, anti-adhesive behavior, corrosion resistance, reflectivity, brightness, suitability for food applications and chemical resistance.

Hard Chrome Plating Its Past, Present and Future

In the long run, a hard trivalent chrome coat may provide an alternative to hexavalent chrome that would allow chrome platers to maintain their client set in critical wear coating markets. To date, however, there is no satisfactory hard trivalent chrome process, but a number of companies and consortia in the U.S. and Europe have initiated development efforts. Get price

Electroplating costs calculation

At this point, in order to get the plating time per part, one must divide the total plating time by the bath's content capacity b [dm 2], and then multiply by the component's surface. Usually, baths' sizes vary from 200 l (small local industries) up to 4000 l (large industrial plants).The bath's content capacity in [dm 2 ] can be estimated as 1/10 of the bath's capacity in liters 1 .
