Abstract:MoS2 coating was deposited on SUS 316 stainless steel substrate by pressure spraying,and the effect of working temperature on its tribological properties was investigated using a linear reciprocating tribometer.The test results show that the tribological properties of MoS2 coating strongly depend on the test temperature.The coating presents good friction reduction under the working temperature of 100~300 ℃,the best durability under the working temperature of 100~200 ℃,and at the working temperature of 300 ℃ the lifetime of the coating is rapidly decreased.Therefore,the optimal working temperature of pressure sprayed MoS2 coating is 100~200 ℃.
