Thickness testing

摘要

To measure the thickness of a coating, many properties have been utilized. Measurements have been described that use the atomic configuration, electrochemical equivalent, corrosion rate, electrical conductivity, magnetic properties, density, and actual linear measure of the coating. ion addition to these methods, tests have been successfully performed by using the electrical resistance and transparency of the coating. Each of these methods has its proper application. It is obvious that one system is not capable of satisfying the needs of every plater.
