Effect of sulfurizing temperature on frictional behavior of tungsten disulfide thin film
硫化温度对硫化钨薄膜摩擦性能的影响

Tungsten oxide thin films were prepared on 3Cr13 martensite stainless steel, and then the films were sulfurized in a quart heating-furnace with quantitative sulfur at 200, 400, 600 and 800  for 4 h. The effect of the sulfurizing temperature on frictional behavior of the tungsten disulfide thin film was studied. The results showed that the sulfurizing temperatures influenced surface topography and crystallization obviously. But the influence on chemical constitution was not obvious. The frictional behaviour of the stainless steel basal plant subjected to be sulfurized was improved. With the increasing of the sulfurizing temperatures, the fiction coefficient of the films reduced and the fiction coefficient was also influenced by the testing environment and conditions.
