| description | The main aim of the study is to consider the surface fracture on fatigue wear mechanism of conventional metals and NiTi, to introduce comparative experimental results which show that NiTi wear resistance is much higher than traditional anti-friction metal; to disclose the nature of increased wear resistance of NiTi. Methods and materials: The authors have studied TiNi alloys of three compositions: Ti[50]Ni[47,5]Fe[2,5] (ТН-1К), Ti[49,4]Ni[50,6], Ti[49,9]Ni[50,1]. on the friction machine SMT-1. The study was carried out on the surface layers on a microscope of the "GSEM instruments" nanohardness gage and on the 3D profilograph-profilometer "Still". The results: The authors determined the fatigue wear as the main form of wear by introducing a number of conditions not disturbing the performance of real friction units. The paper considers wear particle formation due to formation of subsurface cracks. The increased durability of NiTi in comparison with conventional materials was proved experimentally. |
