Cr-based coatings were prepared by cathode arc evaporation technology using N 2 and C 2 H 2 as reactive gases. Three compositions were investigated, Cr 60 N 40 , Cr 41 N 27 C 32 and Cr 67 C 33 .The present investigation is centred on the structural stability via coatings tempering up to 1000ºC, by in situ X-ray diffraction in inert atmosphere. As-deposited coatings present low order structure with a medium feature size less then 10 nm. The hexagonal β-Cr 2 N phase, characteristic of binary Cr 60 N 40 coating, was stable up to 900ºC, before recrystallization and grain growth takes place. For Cr 41 N 27 C 32 film the phase transition varies from the metastable δ-Cr(N,C) to orthorhombic chromium carbonitride Cr 3 (C x N 1-x ) 2 phase up to 800ºC and then to chromium carbide phase. No chromium nitride phases were detected in spite of the similar N and C contents after the deposition. The Cr-C coating recrystallizes into a mixture of carbide phases, mainly Cr 3 C 2 and Cr 23 C 6 after 1000ºC annealing treatment.

“…There was no significant change in the grain size. That differentiates study coatings from TiN coatings where significant increase of grain size is observed at annealing temperatures of 500 • C [22]. This difference may be due to blocking effect of copper and nickel located along the (Ti, Al)N grain boundaries on the processes of coagulation and recrystallization growth.…”

“…More fundamental information of the underlying decomposition mechanisms of the material itself is not extensively covered in literature. Only the main decomposition route of pure CrN via the release of nitrogen through Cr 2 N to Cr is well established [7][8][9]. However, large discrepancies already appear regarding such fundamental parameters like the onset temperatures of these reactions.…”
