摘　　要：文章以磷酸和五氧化二磷为主要原料,氧化镁和氢氧化铝为固化剂、三氧化铬为钝化剂,二硫化钼粉体为填料,按照一定配比进行液相反应制成磷酸盐基二硫化钼涂料,并对二硫化钼润滑涂层进行性能检测,结果表明:以磷酸盐体系为粘结剂的二硫化钼润滑涂层具有很高的结合强度,和优异的耐摩擦性,涂层在200℃和300℃的摩擦系数均低于常温状态下的摩擦系数,在200℃时降低至0.1左右,是优良的固体润滑涂层,二硫化钼润滑涂层的使用温度应低于400℃。In this paper,phosphate based lubricating coating was prepared by liquid phase reaction with phosphoric acid and phosphorus pentoxide as main raw materials,magnesium oxide and aluminum hydroxide as curing agent,chromium trioxide as passivator and MoS2 powder as material.The performance of the MoS2 lubricating coating was tested.The results show that MoS2 lubricating coating with phosphate system as the binder has high bonding strength and excellent friction resistance.The friction coefficient of molybdenum sulfide sliding coating at 200℃and 300℃is lower than that at room temperature.At 200℃,the friction coefficient decreases to about 0.1.It is an excellent solid lubricating coating.The service temperature of MoS2 lubricating coating shall be lower than 400℃.
