Convoluted protective hose

A plain bearing having a metal backing, a bearing lining secured to the backing and an overlay plated to an interlayer, which is itself plated onto the bearing lining, is disclosed. The bearing lining is formed from an alloy based on aluminum or copper. The overlay is formed of an alloy of zinc with 0.5 to 25% by weight of a metal selected from nickel, cobalt and iron, and the material of the interlayer is selected from nickel and copper.

Composite sliding contact bearing

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.

Bearings having an overlay coating containing dispersed phase of a

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.

Method for etching piston rings

Alloys of the type known as overlays for bearings are described. An overlay for a bearing comprises between 0.5 and 15 wt % of cobalt the balance being tin apart from incidental impurities.

Tin-cobalt bearing overlay alloys

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.
