Moisture-Resistant MoS sub 2 -Based Composite Lubricant Films

The moisture resistance of sputter-coated composite films of MoS sub 2 can be markedly increased when the MoS sub 2 is sputter deposited with water-repellent additives. To increase the adhesion of such coatings and to prevent corrosive attack of the substrate, generally steel, a thin corrosion-resis...

Description
Summary:The moisture resistance of sputter-coated composite films of MoS sub 2 can be markedly increased when the MoS sub 2 is sputter deposited with water-repellent additives. To increase the adhesion of such coatings and to prevent corrosive attack of the substrate, generally steel, a thin corrosion-resistant sulphide-forming intermediate layer is applied previously on the functional surface and serves as an interlayer. With a sputtering process, coatings of these lubricants, which are durable in the Earth's atmosphere and adhere well to their support, are obtained. Friction and wear results for such composite lubricant films on different interlayers and various substrates, which were obtained in dry and humid air from pin and disc experiments and from functional bearing elements of precision engineering systems, confirm the improvements. 14 ref.--AA
