The wear behaviour of laser-clad TiC-Ni alloy coatings was studied by X-ray diffraction, scanning electron microscopy, transmission electron microscopy and pin-on-ring friction and wear tests. TiC particles can act as hard barriers to resist the scoring and plastic deformation of the matrix and then delay the occurrence of delamination without distinctly increasing the friction coefficient of the coatings. The degree of wear depends mainly on the extent of debonding and removal of TiC particles… CONTINUE READING
