TiN coatings and some particle of TiN were prepared by reactive plasma spraying, in which titanium powder react with nitrogen under different flow rate, at the same time keeping all other parameters invariableness. The microstructure of the TiN coatings and particles were analyzed by means of SEM and the rate of TiN coating was tested by XRD. The results show that the microstructure and transformation rate of TiN coatings are greatly affected by nitrogen flow rate. The microstructure and transformation rate of TiN coatings were the best when the nitrogen flow rate was 1500 L/h.
