Corrosion Resistance of Industrial Hard Chrome Plating
Chromium is a hard, brittle, tensile-stressed metal that has good corrosion resistance to most materials. As it builds in thickness it develops a pattern of tiny cracks because the stresses become greater than the strength of the coating. These cracks form a pattern which Interlaces and sometimes extends to the base metal. A corrosive liquid or gas could penetrate to the base metal. This can be prevented in three ways. A nickel undercoat can be applied to provide a corrosion resisting barrier; the chrome plating can be applied to maximum thickness; or a thin, dense chrome can be substituted.
The following table is a general indication of the resistance to chromium to various corrosive agents. The corrosive resistance of chromium in actual use is affected by operating factors, such as temperature. concentration, areation and the-presence of small amounts of other constituents in the corrosive medium so that the data in this table must be considered only as an approximation. For critical conditions it may be preferable to conduct tests in the actual solution in use and under the actual operating conditions.
