Abstract
A method for producing cylinder linings in an aluminum or magnesium engine block for an internal combustion engine utilizes plasma spraying of a mixture of powdered molybdenum and powdered steel containing from about 10 to about 70 wt. % molybdenum and from about 90 to about 30 wt. % steel. The resulting slide layer has good adhesion to the engine block and has high wear resistance.
Claims7
A method for producing a slide surface on a metallic body to provide hydrodynamic lubrication in use comprising:
- applying a wear layer to an aluminum alloy surface by thermal spraying, the wear layer having a microporous surface and containing particles to be broken out to form isolated micropores;
- and
- machining the wear layer to break out particles to produce isolated micropores to produce a slide surface having isolated lubrication pockets to form a microchamber pressure system.
A method according to claim wherein the powdered steel is an alloy tool steel.
