Powder metallurgy method

Abstract

The invention provides a powder metallurgy method. Raw materials are adopted in percentage by weight: 9.3 percent of micro-powder wax, 2.1 percent to 4.4 percent of beryllium powder, 4.1 percent to 5.2 percent of zinc stearate, 4.3 percent of an anti-wear agent, 5 percent of tungsten powder, 2 percent of europium powder and the balance of lead powder and difficult-to-remove impurities; the powdermaterials are stirred for 5h to 6h at high temperature of 260 DEG C to 280 DEG C by utilizing a stirrer, are sufficiently mixed and then are subjected to mixed pressing, die casting and fine pressingto obtain a finished product. The powder metallurgy method has the advantages that the structure is simple, the tensile strength and the rigidity of the product are improved and the service life of the product is greatly prolonged.

Description

technical field

[0001] The invention relates to a powder metallurgy method. Background technique

[0002] Powder metallurgy is a process technology for producing metal powder or using metal powder (or a mixture of metal powder and non-metal powder) as raw material, forming and sintering to manufacture metal materials, composite materials and various types of products. The powder metallurgy method has similarities with the production of ceramics, and both belong to the powder sintering technology. Therefore, a series of new powder metallurgy technologies can also be used for the preparation of ceramic materials. Due to the advantages of powder metallurgy technology, it has become the key to solve the problems of new materials and plays a pivotal role in the development of new materials. Powder metallurgy includes powder making and products. Among them, milling is mainly a metallurgical process, which is consistent with the literal meaning. However, powder metallurgy produc...
