The following tips will be of use in solving various problems and defects that can arise when doing hard chrome plating. The chrome bath can be one of the most forgiving of all of the plating processes, when its used properly. The techniques and equipment components, however, are sometimes more critical than for other plating types. A defect may not be caused by a single item as certain variables can be accumulative in nature.

The best cure is one of prevention. Rejected and re-plated parts are expensive. This cost always exceeds that of doing it right the first time. A rigid program should be established for preventive maintenance that includes both the plating bath and the equipment components. The operational procedures should also be reviewed to ensure that the proper techniques are being followed.

Troubleshooting Guidelines
Faulty operation of the plating bath, improper techniques, inadequate equipment and other factors are typical causes of defects. The exact cause of a particular defect can be any one of many factors.

This data is based on over fifty (50) years of experience with chromium plating. It outlines various problems that can be encountered along with possible remedies. The following Topics are covered:
