| 摘 要： | 以TiFe粉、Ni粉和蔗糖(碳的前驱体)为原料，通过蔗糖的热分解碳化制备Ti-Fe-Ni-C系反应热喷涂复合粉末，并利用等离子喷涂制备了TiC/Fe-Ni复合涂层。复合涂层主要由TiC颗粒均匀分布于(Fe、Ni)固溶体中形成的复合强化片层构成，片层中TiC颗粒呈球形或近球形，粒度为亚微米级和纳米级。TiC/Fe-Ni复合涂层的耐冲蚀磨损性能研究表明：涂层冲蚀失重率随攻角的增大而增加，表现出脆性材料冲蚀特性，但冲蚀失重率对攻角不敏感，涂层具有较好的塑性与硬度的配合；复合涂层的耐冲蚀磨损性能优于相同工艺条件下制备的Cr2C3/Ni-Cr复合涂层，约为20G钢的2倍以上。

| Abstract: | Ferrotitanium powder,nickel powder and sucrose(carbonaceous precursor) were used as raw materials.A kind of Ti-Fe-Ni-C composite powder for reactive thermal spraying was fabricated by heating a mixture of ferrotitanium,nickel and sucrose to carbonize the sucrose.TiC/Fe-Ni composite coatings were prepared by plasma spraying of the Ti-Fe-Ni-C composite powder.It shows that the composite coatings are mainly composed of layers in which the TiC particles are uniformly distributed within(Fe,Ni) solid solution all... |
