Slower cooling rates may be required to reduce cracking where greater thicknesses are needed or where there is a sub- stantial difference in the thermal expansion coef- ficients between the coatings and the substrate. The guideline for this process is set forth in NACE Specification RP0394-94. Physical vapor deposition (PVD), sometimes (especially in single-crystal growth contexts) called physical vapor transport (PVT), describes a variety of vacuum deposition methods which can be used to produce thin films and coatings.
