| 摘 要： | 文本通过实验研究,证明了在低气压等离子喷涂条件下,TiO_2涂层的机械性能不是依赖于涂层结构,而主要由形成涂层前的TiO_2粒子的温度和速度所决定;如果形成涂层前的TiO_2粒子温度越高并且速度越大,就能形成更加扁平状粒子的涂层,增加粒子间结合力,使涂层机械性能提高。因此,喷涂规范中的等离子弧功率、喷涂距离和喷涂室压力对涂层机械性能有较大影响,而等离子弧辅助气氢气流量的影响甚小。

| Abstract: | It is proved by experimental investigation presented in this paper that, under the condition of low pressure plasma spraying, the mechanical properties of TiO2 coating are not dependent on the coating structure but mainly decided by the temperature and speed of TiO-2 particles prior to the formation of coating. For higher temperature and speed of TiO-2 particles, a more flatshaped powder coating is formed, more intense binding forces between the particles occur, and higher mehanical properties of coating are obtained. Therefore the spraying parameters such as plasma power, spraying distance, and the pressure of spraying atmosphere exert an great influence on the mechanical properties of the coating while the effect of the flow rate of auxiliary H2 gas is very small. |
