Abstract:To investigate the process method to inhibit the cracking of the laser cladding layer, based on the concept of synchronized micro-forging, this paper applies a self-developed laser cladding synchronized rolling auxiliary device to prepare Ni60-WC cladding layer by laser cladding on the surface of Q235 steel substrate. An optical microscope, scanning electron microscope, Vickers microhardness tester, X-ray diffractometer, friction and wear tester, and three-dimensional optical profilometer were used to observe,… Show more
