Abstract: 1,257,757. Making piston rings. NIPPON PISTON RING K.K. 29 July, 1970, No. 36762/70. Heading B3A. [Also in Divisions C7 and F2] A method of making a piston ring in which a cast iron or cast steel blank is electroplated at least on its rubbing face with a layer of CoW, heat treated at temperatures between 200‹ and 500‹ C. and then left to cool. The sliding surface of a blank is honed using an abrasive, with a grain size between 200 and 220 mesh, mixed with water in a ratio of 10 : 100 by spraying the mixture at an angle of 45 degrees under a pressure of 6 kg./cm.<SP>2</SP> from a distance of 30- 50 mm. The layer of CoW is applied by electroplating which is carried out in a bath at a temperature of 37‹ C. at a pH of 7À0, with a current density of 3 Š/dm.<SP>2</SP> for 2À5 hours. The bath contains sodium tungstenate and cobalt sulphate, with tartrates added. The plated ring is heat treated at temperatures between 200 and 500‹ C. and then allowed to cool to give the CoW layer a hardness of between 800 and 1200 Vickers.
