directly, reducing the abrasion between surfaces of friction pairs remarkably. Under high temperature, tungsten disulfide is oxidated slowly and becomes tungsten oxide (WO3), which can prevent tungsten disulfide from being oxidated further, besides, tungsten oxide has low friction coefficient and the same lubricating properties as tungsten disulfide, so it also has the ability to reduce the abrasion......
