Abstract

The invention discloses a water atomization manufacturing method of silver containing super-performance copper alloy powder. The silver containing super-performance copper alloy powder comprises the following main components in a ratio by weight parts: 90.0-93.5% of copper, 5.0-7.0% of tin, 0.8-1.2% of silver and 0.5-1.5% of copper phosphate. The water atomization manufacturing method of the silver containing super-performance copper alloy powder has the advantages of great ductility, excellent machining performance and high wear resistance.

Description

technical field [0001] The invention relates to a water atomization manufacturing method of silver-containing super-performance copper alloy powder. Background technique [0002] As a rotating component, the engine bearing is destined to require super wear resistance due to its working method. Many existing engine bearings are made of lead-containing alloy materials, which have certain deficiencies in wear resistance and machining performance. [0003] However, due to the different manufacturing methods of the existing few silver-containing alloy materials, there are generally problems such as the inability of the silver material to be completely fused, resulting in the failure of the ductility to meet the expected goal. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a water atomization manufacturing method of silver-containing super-performance copper alloy powder with good ductility, good machinability and hi...
