摘要
采用真空多弧离子镀技术在X12CrMoWVNbN10-1-1耐热钢表面沉积Ti(CN)涂层,研究了涂层的组织和性能,并对涂层的抗热震和抗氧化性进行了研究。结果表明,采用适当的沉积温度、压力及N2流量,可以在X12CrMoWVNbN10-1-1耐热钢表面得到以Ti(CN)为主的致密涂层,在沉积温度400℃时,该涂层的最高硬度可达2438.7HV0.025,涂层在650℃以下具有良好的抗氧化性能,在700℃以下具有良好的抗热震性能。
Ti（CN） coating was deposited on X12CrMoWVNbN10-1 1 heat-resistant steel by vacuum multic-arc ion plating. The surface morphology and composition of the coating were studied by scanning electron microscopy, and the thermal shock and oxidation resistance of coating were also studied. The results show that it was got a dense coa- ting of Ti （CN） on X12CrMoWVNbN10-1-1 heat-resistant steel surface, with appropriate deposition temperature, pressure and N2 flow. At the deposition temperature of 400 ℃, the coating hardness rose up to 2438. 7HV0. 025, the coating has good oxidation resistance at 650 ℃ and good thermal shock resistance at 700 ℃.
