Microhardness is the test that you need.
There are many test labs in CA that can perform hardness testing. However, some are not familiar with special precautions about test methods and sample preparation necessary for good results on thin coatings. Guidelines are given in applicable ASTM specifications, such as ASTM B578-21 [affil. link] and ASTM B488 [affil. link]. Make sure that the lab that you choose is familiar with these specifications and follows them.
