Is the cryogenic treament a coating process?
A. No, the cryogenic process is a one-time, permanent treatment affecting the entire object. It is not a surface coating. The item is chilled to -300 degrees Fahrenheit using a dry nitrogen atmosphere. This has an effect on the entire structure of the part at the atomic level. You should never have to re-cryognically treat a part unless it has been reheated to its fluid state.
