It is known that Ti 3 SiC 2 is the only stable ternary compound in the Ti-Si-C system that demonstrates a good microstructure-properties relationship. The production of Ti-C-Si by detonation spraying technique results in the formation of multilayer Ti 3 SiC 2 /TiC coating. This transformation is due to the deintercalation of Si from Ti 3 SiC 2 that enlarges after heat treatment. This article provides investigations on the effect of middle-temperature annealing on the structural-phase state, mechanical and tribological properties of Ti 3 SiC 2 /TiC coatings obtained by the detonation spraying method. After annealing, the formation of [110], [211] and [301] reflections of TiO 2 phases and an increase in the intensity of [103] and [108] reflections of Ti 3 SiC 2 phases are observed. The maximum hardness of 1400 HV obtained for the coating annealed to 800° C. A similar tendency observed during adhesion tests. An increase in annealing temperature to 800° C, improves the adhesion strength of the coating to 13.2 N. Meanwhile the value of COF remains stable for as-deposited and annealed coating. The property improvements are due to the formation of denser structure and oxideTiO 2 films. |
