Use of MOLYBDENUM DISULPHIDE in association with phosphated surfaces

Experiments were carried out on the load‐carrying capacity and the endurance under light loading of five dry surface treatments. It was found that molybdenum di‐sulphide, rubbed or bonded on to mild steel, gave little effective protection against seizure. The combination of a phosphating treatment with an applied lubricant resulted in a good bearing surface. Of the three additional lubricants tested, a bonded coating of molybdenum di‐sulphide was superior to a coating of paraffin wax, which was itself superior to a coating of molybdenum di‐sulphide rubbed on.
