Abstract

In recent years chromium plating has been subjected to much research due to its ever-increasing demand. The results of these investigations have demonstrated the valuable properties of this plate. Of its many advantageous properties, hardness is one of the outstanding ones, but its application in industry is as yet not fully realized. This being due to the fact that it is difficult to produce a plate that is uniform and does not chip. Many chemists have investigated the porosity of the chromium plate in order to produce a coating that could be used for protective purposes, but there seems to be few who studied the hardness of the chromium plate. If it were possible to produce a plate that does not chip, the whole tool industry would be benefitted. There are various methods to test for hardness, all having their good and bad points. The simplest and one of the best is by testing the resistance against abrasion. In this thesis the hardness and porosity are studied simultaneously in order to combine greatest hardness with maximum corrosion resistance.
