Nickel Plating Problem
We have a problem with our acid nickel bath. What was once a bright nickel color is now a gray color, although it still looks bright. When we set the rectifier to the correct amperage for the load, the parts appear to burn. Also, we can only leave the parts in for about 1 to 3 min or they will start to turn black and smoky-looking. Any suggestions as to what the problem might be?

Functional Trivalent Chromium Electroplating of Internal Diameters
This paper discusses recent research work on the development of a functional trivalent chromium plating process from a trivalent-based electrolyte to replace hexavalent chromium plating. Hexavalent chromium plating has been used for many years to provide hard, durable coatings with excellent wear and corrosion resistance properties. However, hexavalent chromium baths have come under increasing scrutiny due to the toxic nature of the bath, effects on the environment and workers’ health. In this paper are results from our development program aimed at achieving properties comparable to existing hexavalent chromium plating for functional applications. Specifically, recent efforts in plating chromium on the internal surfaces of cylindrical parts will be presented, as well as wear test data.
