Chrysler – PSPLATING

This standard outlines the procedures and requirements for electroplated zinc, and mechanically plated zinc coatings on iron and steel parts for corrosion protection. This standard provides the procedures and requirements for producing electroplated zinc deposits. Parts with a hardness of HRC 32 or higher MUST be electroplated according to PS-4220 which requires a mandatory bake operation to relieve hydrogen embrittlement. PS-4220 is identical to PS-79 respectively, except for the mandatory bake. This standard also covers the requirements for mechanically plated zinc deposits. The following Process Standards, which were formerly all individual standards and are still referenced.
