| Abstract Scope |
42CrMo steel is a kind of medium carbon allof steel mainly used for manufacturing heavy duty transmission parts. Laser cladding is an advanced surface technology, and it can be applied to improve wear and fatigue resistance properties by getting a high surface hardness. In this paper, pulse laser cladding experiments were conducted on 42CrMo surface with the powder of T15 high speed steel. The microstruture and of cladding layer were observed by optical microscopy (OM) and scanning electron microscopy (SEM). The hardness gradient of section was tested. The hardness of surface and substrate is 747 HV and 195 HV. After friction and wear testing, the average dry friction coefficient is 0.448 and the volume loss is 689100 µm3. |
