Abstract : The authors review the results of Czech research on methods of antifriction surface-treatment of iron-base materials and the experience of the industry with these methods. Two methods are discussed: sulfidizing and the use of solid molybdenum-disulfide-base lubricants. Originally sulfidizing was done in a fuzed-salt bath, but lately numerous plants have introduced sulfidizing in a gaseous atmosphere (sulfonitriding). The present capacity of sulfidizing equipment is about 3000 tons per year with two daily shifts. A wider use of solid molybdenum-disulfide base lubricants dates back to 1960 when some Czech chemical plants began to produce molybdenum disulfide. Lately molybdenum disulfide has been used as such and in combinations with conventional lubricants in numerous applications, including the lubrication of moving machine parts and metal-forming operations.
