摘　　要：采用自约束热疲劳试验方法研究了ＴｉＮ等离子气相沉积层对３ＣｒＺｗ８Ｖ钢热疲劳性能的影响。结果表明：ＴｉＮ沉积层可以有效地提高钢的热疲劳抗力，且随沉积层厚度减薄，热疲劳抗力增加；随热循环上限温度升高，ＴｉＮ沉积层的热疲劳抗力降低；ＴｉＮ沉积层具有很的热循环稳定性及抗氧化性。Influence of plasma vapour deposited TiN coating on the thermal fatigue property of 3Cr2W8V steel was studied by means of self-constraint thermal fatigue test. The results show that TiN coating can effectively improve the thermal fatige resistance of 3Cr2W8V steel.The thickness of deposited coating decreasing,the thermal fatigue resistance increase. The thermal fatigue resistance of TiN coating cuts TiN coating cuts down with the thermal cyclic upper temperature rising;TiN coating possesses highter the stability of thermal cycle and oxidation resistance.
