Abstract:

Experiments were made, using a pin and ring machine, to measure the influence of surface roughness, humidity and chemical composition on the endurance of rubbed films of lamellar solids. An optimum film life is exhibited on substrates of roughness approximately 30-40 microns in CLA. An environment of high relative humidity during film formation leads to enhanced endurance whilst high humidity during film testing leads to reduced endurance. The coefficients of friction increase with increasing relative humidity of the environment. It is tentatively suggested that the inability of Group VA metal dichalcogenides to lubricate mild and tool steel may be due to their probable non-stoichiometric composition. Author
