Abstract
Abstract TiB2/metal composite material was prepared by magnetic-field-assisted laser cladding on Ti–6Al–4V to improve wear resistance and decrease crack sensitivity. The influences of the magnetostrictive effect on the crack sensitivity and mechanical properties were studied. Moreover, the effects of the magnetic field on the microstructure, lattice parameters, and wear properties of the laser layers were investigated. TiB2 particles were synthesized on the surface of the Ti–6Al–4V alloy in situ by laser cladding. The magnetic intensity influenced the mechanical properties of the laser cladding layers. The wear properties of the composite cladding layers were improved by increasing the hardness and decreasing the elastic modulus of the cladding layer. The lattice mismatch phenomenon in the cladding layer was reduced, and the mechanical properties of the cladding layer were enhanced by introducing a magnetostrictive effect. The application of 20 mT magnetic intensity was appropriate for generating a negative magnetostrictive effect, and the lattice misfit parameter, wear volume, and coefficient of friction were the lowest among all the samples.
