1,205,096. Bearings; lubricating. BALL BROS. RESEARCH CORP. 26 Nov., 1968 [22 Dec., 1967], No. 55959/68. Heading F2A. A method of dry lubricating a surface comprises adhering a coating of molybdenum disulphide, for example, to a peening ball and impacting the peening ball on the metal surface to transfer and fuse a portion of the molybdenum disulphide to the surface. Other dry lubricants include tungsten disulphide, titanium disulphide, molybdenum diselenide, tungsten diselenide, niobium diselenide and molybdenum ditelluride and these may be used to lubricate surfaces of metal, plastics or ceramic. As shown in the drawing a peening ball 10 is ' coated with dry lubricant 11 and is propelled towards a surface 12. The impact forms an indentation 14 which retains a portion 16 of the dry lubricant 11 when the ball 10 rebounds. |
