利用５ｋＷ的ＣＯ＿２激光加工机重熔Ｆｅ－Ｎｉ－Ｃｒ－Ｂ－Ｓｉ－Ｍｏ－Ｃ（Ｆｅ基）、Ｎｉ－Ｃｒ－Ｂ－Ｓｉ－Ｆｅ－Ｃ（Ｎｉ基）和Ｃｏ－Ｃｒ－Ｂ－Ｗ－Ｃ（Ｃｏ基）自熔合金涂层，矾究了激光重熔层的组织、相结构、化学成分分布和耐磨性、强韧性等，研究结果表明，利用高能量密度的激光束重熔涂层，可使显徽组织明显细化，合金元素分布均匀，硬质相弥散分布，显著改善了火焰喷焊层的强韧性，提高了耐磨性，是改善火焰喷涂层或喷焊层性能的有效途径。
The Ni-Cr-B-Si-Fe-C (Ni-based) and Co-Cr-B-W C (Co) self-fluxing alloy coating and alum were used to study the microstructure, phase structure, chemical composition distribution, wear resistance and toughness of the laser remelted layer. The results show that laser beam remelting with high energy density Coating, can significantly reduce the apparent microstructure of the organization, the distribution of alloying elements, hard phase dispersed, significantly improving the flame spray coating toughness and improve the wear resistance, is to improve the performance of flame spray coating or spray coating Effective way.
