Abstract

The present disclosure pertains to a method of preparing a test specimen for testing of the bonding strength of a layer of additive material to a crystalline substrate, or testing of the bonding strength of one layer of additive material to a second layer of additive material, where both layers of additive material overlie a crystalline substrate. The method includes both test specimen “cutting” from a large sample of material and preparation of an individual test specimen for four-point adhesion testing. Also described is a fixture which is useful for cutting the individual test specimen from the large sample of material.
