Preparation of a novel Ni/Co-based alloy gradient coating on surface of the crystallizer copper alloy by laser

Microstructural evolution and wear behaviors of laser cladding Ti 2 Ni/α(Ti) dual-phase coating reinforced by TiB and TiC

“…The results showed that the microhardness was gradually decreased from the coating to the substrate due to the gradient distribution in microstructure. The similar results were also obtained by many researches [18][19][20]. Present studies mainly paid close attention to the effect of the gradient distribution in microstructure on the mirohardness.…”

Electrical contact strengthening of induction-clad Ni–40% WC composite coatings on 40Cr substrates

“…The heated substrate area, which was denoted the heat affected zone (HAZ) [2], had a higher hardness. The microhardness gradient at the interface not only helped to improve the wear properties but also increased the bonding strength between the two neighbouring layers [19].…”

Study of laser cladding Fe–Co duplex coating on copper substrate

“…In order to improve the bonding strength and reduce the crack sensitivity of copper substrate and Co-based coating, preparation of transition layers might act as a recipe [14][15][16][17]. For example, Liu et al [14] successfully prepared crack-free Ni-Co biphasic coating on copper substrates by continuous laser cladding of Ni-based and Co-based coatings.…”

“…For example, Liu et al [14] successfully prepared crack-free Ni-Co biphasic coating on copper substrates by continuous laser cladding of Ni-based and Co-based coatings. Chen et al [15] prepared Ni/Co based alloy coating with high wear resistance of gradient on the surface of copper alloy by YAG laser in situ induction reaction method.…”
