Abstract: A plain bearing comprising a metal backing, an aluminium based bearing alloy layer and a sacrificial overlay of pure tin applied directly to the bearing material without a nickle interlayer. The bearing alloy comprises by weight, 1 to 11% silicon, 8 to 35% tin, 0.2 to 2% copper with the balance being aluminium.

Abstract: Bearings having an overlay (14) deposited by cathodic sputtering. In one example the overlay comprises an aluminum matrix (22) containing a dispersed phase (24) of tin. The overlay may contain a relatively low content of tin adjacent the interface (18) with the substrate (10;12) rising to a relatively high content at the surface. The surface may comprise a layer (26) of substantially pure tin to act as a sacrificial overlay during initial running of the bearing.

Abstract: Bearings are described having composite overlay coatings. The composite overlay coating comprises an electro co-deposited soft metallic matrix having incorporated therein from 0.05 to 2 wt % of a hard metal oxide, said material exhibiting a Vickers hardness (Hv) of from at least 300 to in excess of 600.

Abstract: A method for the etching of chromium-coated piston rings comprises the steps of producing relative movement and rubbing contact between the chromium-coated surface of a piston ring which is anodic and a cathode having a porous material on the rubbing surface thereof, supplying an electrolyte to the porous material between the anodic ring surface and the cathode, establishing an electrical potential therebetween and supplying an electrical current for a period of time during the relative movement.
