| description | The invention discloses a preparation method of a modified nickel-based wear-resistant coating for an automobile engine piston, and belongs to the technical field of automobile engines and surface treatment. According to the process, 70%-90% of Ni60 alloy powder and 10%-30% of tungsten powder are doped to obtain mixed powder, the obtained mixed powder is sprayed to the surface of a pretreated base body through the plasma cladding technology, and the modified nickel-based wear-resistant coating is formed through cladding. The Ni60/W coating is prepared through plasma cladding, a large number of hard phases are separated out from the coating, the hardness and the abrasion resistance are greatly improved, and the performance requirements of the automobile engine piston in the severe working environment can be met.
本发明公开了一种用于汽车发动机活塞的改性镍基耐磨涂层的制备方法，属于汽车发动机和表面处理技术领域。本发明工艺将70%-90%的Ni60合金粉末和10%-30%的钨粉掺杂得到混合粉末，采用等离子熔覆技术将所得混合粉末喷涂至预处理后的基体表面，熔覆形成改性镍基耐磨涂层。本发明通过等离子熔覆制备得到Ni60/W涂层，涂层中析出了大量的硬质相，硬度与耐磨性得到了极大的提升，能够满足汽车发动机活塞严苛工作环境 |
