| Abstract Scope |
Laser cladding is a surface modification technology used to enhance the interface performance of gear rims in heavy-duty vehicles, which often suffer from insufficient performance due to harsh environments. This study investigated the effects of process parameters and cladding direction on the interface performance of the cladding layer to improve bonding strength and wear resistance. T15 high-speed steel powder was used in laser cladding of 42CrMo samples, examining the effects of different scanning speeds. Results show that increasing the scanning speed from 6 mm/s to 9 mm/s raised the average interface bonding strength from 426.78 MPa to 542.66 MPa. This enhancement is mainly due to reduced grain size with higher scanning speeds, which prevents the timely precipitation of certain alloy elements. These elements combine with carbon to form a significant amount of hard alloy carbides, thereby improving the interface performance. |
