一种 Fe基非晶合金粉末 (含 Si,B,Cr,Ni等 )被用于大气等离子喷涂试验 ,结果表明 ,采用等离子喷涂工艺成功地制备出了一种高非晶含量的 Fe基非晶合金涂层 ,涂层各区域的组织均匀一致 ,涂层由变形良好的带状粒子相互搭接堆积而成 ,涂层致密度高 ,孔隙率低 ,氧化物含量较少 ,并具有很高的硬度 ,显微硬度在 5 30～ 790 Hv0 .1范围内 ,涂层与基材结合良好 ,结合强度可达 2 7MPa以上 ,能够满足实际使用要求 An Fe-based amorphous alloy powder (containing Si, B, Cr, Ni, etc.) was used in the atmospheric plasma spraying test. The results show that a high amorphous content Fe-based amorphous Alloy coating, the coating uniform in all regions of the organization, the coating by the deformation of the good lamellar particles lap stacked together, the coating of high density, low porosity, less oxide content, and has a high Hardness, microhardness in the range of 5 30 ~ 790 Hv0. 1, the coating and substrate bonding well, the bonding strength of up to 2 7MPa or more, to meet the actual use requirements
