ABSTRACT

Thermal stability of TiAlBN and TiN/TiCN hard coatings was studied by evaluating the stress-temperature curves and the wear resistance after annealing up to 1123 K. The microstructure, phase composition and hardness were studied prior and after annealing.
Prior to annealing, a correlation between the residual stress and hardness was observed. After annealing, the compressive stresses of the TiAlBN coatings decreased from 1.0 GPa to less than 0.2 GPa, while the hardness remained constant or increased from ~10 GPa to ~25 GPa. The hardness increase of the coatings after annealing is related to the self-hardening effect.
The effect of the plasma nitriding mode prior to the deposition of 3 μm thick TiCN or TiN/TiCN coatings on the wear resistance of the duplex-treated coating (nitriding and deposition) was studied. The stability of the wear resistance of the duplex treated-coating was also examined after one hour of annealing at 1123 K. It was found that the plasma-nitrided layer in the duplex treatment maintains the wear resistance stability of the annealed duplex-treated hard coatings.
