Optimization of Chrome Plating Processing Condition

Abstract

In aircraft engines, shafts and other sliding members are plated with thick and very hard chromium layers to increase their resistance to wear. When nonconformities such as pits, cracks, or uneven plating have occurred in the chrome plating process, it has been difficult to assess the causes by conventional methods. In this study, we considered the generic function of plating and performed an optimization experiment by parameter design. As a result, compared with existing methods, variation was reduced to one fourth and productivity was doubled.
