摘要

为探究固体润滑剂Ag 在机械球磨制备复合涂层中的存在形式和复合涂层的宽温域摩擦学性能，设计间接加入固体润滑剂Ag 的方法在铝合金表面机械球磨制备Ni-Al-Ag 自润滑复合涂层，并对涂层组分、力学和摩擦学性能进行了分析表征。结果表明:经过预先球磨制备复合涂层组织均匀分布，无滑移裂纹产生。经过热处理后，4 种预先球磨时间(0，6，12，18 h)制得的复合涂层中有不同的Ni-Al 系金属间化合物生成。随着预先球磨时间的延长，涂层硬度有上升趋势，预先球磨12 h 和18 h 复合涂层显微硬度约250 HV。铝合金基体在室温下摩擦系数约0.37，磨损率约1.48×10-3mm3/(N·m)，200 ℃和350 ℃温度下摩擦过程中发生严重黏着现象。预先球磨12 h和18 h 制备的自润滑复合涂层的摩擦系数分别约为室温下0.19，0.16；200 ℃下0.25，0.25；350 ℃下0.27，0.25，磨损率处于(1.5～4.0)×10-4mm3/(N·m)之间。自润滑复合涂层的制备在室温至350 ℃下进行有效地保护了铝合金基体，拓宽了铝合金基体的使用温度范围。

Abstract

In order to investigate the existence form of solid lubricant Ag in mechanical ball milling preparation of composite coating and the wide temperature range tribological properties of composite coating，a method of indirectly adding solid lubricant Ag was designed to prepare Ni-Al-Ag self-lubricating composite coating on aluminum alloy surface by mechanical ball milling，and the components，mechanical and tribological properties of the coating were analyzed and characterized.Results showed that the microstructure of the composite coating prepared by pre-ball milling was evenly distributed，and no slip cracks occurred.After heat treatment，different Ni-Al intermetallic compounds were formed in the four composite coatings prepared with four pre-ball milling times (0，6，12，18 h).With the prolongation of pre-ball milling time，the hardness of the coating tended to rise，and the micro hardness of the composite coating after pre-ball milling for 12 h and 18 h was about 250 HV.The friction coefficient and wear rate of the aluminum alloy substrate were about 0.37 and 1.48×10-3mm3/(N·m) at room temperature，and serious adhesion occurred during friction at 200 ℃and 350 ℃.The friction coefficients of the self-lubricating composite coatings prepared by pre-ball milling for 12 h and 18 h were about 0.19 and 0.16 (room temperature)，0.25 and 0.25 (200 ℃)，and 0.27 and 0.25 (350 ℃)，respectively，and the wear rates were (1.5～4.0)×10-4mm3/(N·m).The preparation of self-lubricating composite coating could effectively protect the aluminum alloy substrate at room temperature to 350 ℃，broadening the range of the application temperature of aluminum alloy substrate.
