Abstract

A method of coating a journal (see Group XXXIV) or other rotatable part incorporating or made from molybdenum with molybdenum disulphide in situ, comprises the creation of locally elevated temperatures of 750 DEG C.-850 DEG C. at high bearing spots by means of a metallic phase in the bearing shell, a sulphurizing agent, e.g. oil containing sulphur, reacting with the molybdenum at these temperatures. The metallic phase may be combined with the sulphurizing agent to form a composite mass which is then located in a groove in the shell and pressed against the journal surface. A suitable composite mass is a copper-silver alloy of chips containing 60 per cent. silver in a solid high pressure sulphur type grease. The journal may be coated by electro-deposition, spraying &c. with molybdenum or a molybdenum compound.
