摘　　要：采用某种自制粘结剂代替传统热喷焊的涂层,制备了Ni60自熔合金涂层,探讨粘结剂对涂层显微组织、孔隙率、显微硬度、磨损性能和腐蚀性能的影响。结果表明,与传统热喷焊涂层相比,粘结剂预制涂层的组织细小、孔隙率低,显微硬度、磨损性能和腐蚀性能基本相同,故此技术可以消除传统热喷焊技术的不足,且粘结剂的存在可改变硬质相的存在状态,起到弥散强化的作用。Ni60 self-melting coating was prepared with home-made adhesive replacing traditional hot spray-welding coating.The effects of the adhesive on the microstructure,porosity,hardness,wear property and corrosion property were studied.The results show that the use of adhesive can eliminate the shortage of traditional hot spray-welding technique,for example,low porosity,fine microstructure,the similar wear and corrosion property.The adhesive can change the state of harden phases and play a role of dispersion strengthness.
