    Abstract: An antifriction alloy containing iron, molybdenum and sulphur, and having a low coefficient of friction, even in the dry state, is disclosed. The alloy contains 8.0-26.6% iron, 41.0-62.5% molybdenum and 23.3-40.5% sulphur. The alloy may comprise a matrix of Fe.sub.x Mo.sub.3+y S.sub.4, where x and y are less than 1. (e.g. FeMo.sub.4 S.sub.5) in which is dispersed FeMo.sub.2 S.sub.4 and/or the .epsilon. phase of the Fe/Mo/S equilibrium diagram. The alloy reacts with a material against which it rubs, to form the sulphide of that material on the rubbed surface. The alloy may be made by chemical reaction, fusion, vacuum deposition, or powder metallurgy. It can be used alone, or as a surface layer on, or inclusion in, another material, or it can be dispersed as a powder in a lubricant.
