本文作者制备了等离子沉积Ni-WSe_2-BaF_2·CaF_2-Y-Ag-hBN高温固体自润滑涂层,研究了不同角度金属熔滴Al对该涂层试样表面的粘蚀能力以及在不同温度下的摩擦系数.研究表明:等离子沉积Ni-WSe_2-BaF_2·Ca F_2-Y-AghBN高温固体自润滑涂层在宽温域(30~800℃)的摩擦系数达到0.086~0.299.金属熔滴Al对涂层的粘蚀速度随沉积角度的增加而增加,90°时金属熔滴在涂层与基体表面沉积率最大,此时钢基体的平均沉积率达176.22 mg/(cm~2·s),含hBN的固体自润滑涂层的沉积率为58 mg/(cm~2·s).金属Ni粘蚀物抛磨剥落速率显示,hBN的存在有效降低了金属Al熔滴在涂层表面的粘蚀能力.
The authors prepared high-temperature solid self-lubricating Ni-WSe_2-BaF_2 · CaF_2-Y-Ag-hBN coatings by plasma deposition. The effects of metal droplet Al on the surface of the coating were studied. The friction coefficient of plasma deposited Ni-WSe_2-BaF_2 · Ca F_2-Y-AghBN high-temperature solid self-lubricating coating reached 0.086 ~ 0.299 in wide temperature range (30 ~ 800 ℃) The corrosion rate of the coating increases with the increase of the deposition angle. The maximum deposition rate of the metal matrix reaches to 176.22 mg / (cm ~ 2 · s) at 90 °, The deposition rate of solid self-lubricating coating containing hBN was 58 mg / (cm ~ 2 · s). The polishing rate of metal Ni erosion showed that the presence of hBN effectively reduced the adhesion of metal Al droplets on the coating surface Erosion ability.
