| 摘 要： | 为提高钛合金高温微动疲劳抗力,利用离子辅助电弧沉积技术在TC17钛合金表面制各了TiN/Ti复合膜层,研究了膜层的剖面成分分布、膜基结合强度、膜层显微硬度、韧性、常规摩擦学性能以及抗高温微动疲劳性能.结果表明:利用离子辅助电弧沉积技术可以获得硬度高、韧性好、膜基结合强度和承载能力优异的TiN/Ti复合膜层,该膜层具有良好的抗磨和减摩性能,能够显著地提高TC17钛合金在350℃高温环境下的常规磨损和微动疲劳抗力.然而,TC17钛合金表面喷丸强化后进行离子辅助沉积TiN/Ti复合膜,由于喷丸层残余压应力的显著松弛以及膜层易于开裂和脱落的缘故,微动疲劳抗力则不及喷丸强化或TiN/Ti复合膜单独作用.

| Abstract: | TiN/Ti composite film was prepared on TC17 titanium alloy substrate by ion-assisted-arc-deposition (IAAD) technique for improving fretting fatigue resistance of the titanium alloy at elevated temperature. The composition distribution, bonding strength, micro-hardness, ductility, the plain tribological properties and fretting fatigue resistance at elevated temperature of the film were investigated. The results indicated that with IAAD technique could prepare a TiN/Ti film with high hardness, good ductility, ... |
