Friction of Tungsten-Based Coatings of Steel under Sliding Contact

An investigation was made to determine the effects of tungsten surface coating on the coefficient of friction of sliding contact between lubricated steel surfaces. The four-ball test was modified, using a tungsten carbide ball bearing in the spindle to cause sliding contact onto three hard steel bal...

The four-ball test was modified, using a tungsten carbide ball bearing in the spindle to cause sliding contact onto three hard steel ball bearings coated with tungsten disulfide lamellar dry lubricant coating, with a coating of grease lubrication applied to the ball bearings. The coatings, loads, speed, and grease level were varied to best understand the impact of different conditions on the friction coefficient.https://www.mdpi.com/2075-4442/7/2/14lubricationball bearingsfour-balltungsten carbidegreasetungsten disulfidecoatingssurface treatmentfriction
