摘　　要：利用反应等离子喷涂方法,通过喷涂自制的复合粉成功地制备了TiCN涂层。使用蔗糖作为碳源,采用蔗糖前驱体碳化的方法,将蔗糖和Ti粉混合均匀后经一定热处理进行碳化,使蔗糖生成的C包裹住Ti粉,这种方法得到的复合粉末中C和Ti粉颗粒两者混合非常均匀,接触面积大,反应更加充分。在150℃及250℃下制备复合粉,蔗糖没有完全碳化,不能完全碳化的蔗糖在等离子喷涂时未合成TiCN涂层。采用350℃、Ti︰C的摩尔比为1︰3制备的复合粉,成功制备了TiCN涂层。对涂层的相组成、硬度和组织形貌特征进行了分析,结果表明,涂层的主相为TiC0.2N0.8,并且含有少量TiN,但涂层较疏松,硬度较低,因此,耐磨性能较差。The TiCN coatings were successfully prepared by means of reactive plasma with spraying self-made composite powder in the paper.Cane sugar was used as a carbon source,using the means of Precursor body carbon,sucrose and titanium powder mixing at high temperature after the heat treatment furnace for carbonization.Finally the titanium powder was wrapped by the carbon,so the composite powder was mixed more uniform and could react more fully.TiCN coatings could not be synthesized with the composite powder prepared the temperatures of 150℃and 250℃,because the sucrose was not carbonized totally and could not carbonize to synthesize TiCN with Ti and N2 in the process of spraying.TiCN coatings were successfully prepared by spraying the composite powder under heat treatment at 350℃and which composed of Ti and C at a ratio of 1︰3.The phase compositions,the morphologies,the hardness and the microstructures were analyzed.The results showed that TiCN coatings were consisted of TiC0.2N0.8 phase and a few of TiN,the wear resistance of TiCN coatings was lower because of the looser structure and the lower hardness.
