Effect of magnetic field on tribological properties of Co-based alloy layer produced by laser cladding on 42CrMo
Source abstract
Abstract
Abstract The Co-based laser cladding layer was prepared on the 42CrMo substrate. The magnetic field was applied during the laser cladding process. Magnetic field-assisted laser cladding results in a finer microstructure, which increases the microhardness of the cladding layer and affects the elastic modulus of the material due to magnetostriction. The results show that the cladding material experienced a magnetostrictive effect in the 20 mT-60 mT magnetic field in the laser cladding process, which affects the friction and wears properties. In this study, the highest value of the magnetostriction was produced at 20 mT magnetic field, which was the most effective in reducing wear.
