摘　　要：研究了爆燃喷涂Ni60A粉末涂层的组织与性能。该涂层组织致密,与基体结合强度高,并且该涂层具有优良的耐磨性能及耐腐蚀性能。在涂层上弥散分布着的金属间化合物等硬质相提高了涂层耐磨性,而涂层低的孔隙率则对其耐腐蚀性有重要作用。This paper introduced the detonation spraying process of Ni60A coating and studied the properties of coating. The coating showed not only compact structure and high bonding strength, but also good wear-resistance and anti-corrosion properties. The intermetallic compounds dispersed in the coating can improve the wear-resistance, and the low porosity is important and beneficial to the anti- corrosion property of coating.
