Abstract

TiN coatings were prepared by means of reactive plasma spraying (RPS) titanium powders, and characterized by SEM, XRD and other methods in the paper. In order to optimize spraying process parameters and get a satisfactory spraying effect, the microstructure, the hardness, the organizations and phases of TiN coatings under different spraying power were studied; also the grain size and the laws of crystallization were analyzed. The results showed that TiN coatings were consisted of TiN phase and a few of TiO0.325 and Ti2O3. A large number of small equiaxed crystals, columnar crystals and part of branches crystals formed the microstructure of the TiN coatings. The cross-sectional hardness of the TiN coating was higher than the surface hardness under the same compression load. Moreover, the TiN coatings which were more close to the substrate material had larger undercooling when crystalling, and the grain size was smaller
