Deposition of B, C, N coatings on WC-Co substrates-Analytical problems indicating c-BN formation

Through investigations of substrate reactions the eta-phase (Co6W6C) was observed which showed XRD peaks similar to c-BN and h-BN. It could be proved, that the eta-phase is responsible for the XRD peaks but an explanation for the detected IR peaks of the BN phases could not yet be found.
