Abstract

The invention provides a powder metallurgical formula and technology. The powder metallurgical formula comprises the following raw materials: 48-88 percent of atomized iron powder, 10-50 percent of reducing iron powder, 0.4-1.5 percent of graphite powder, 1-3.9 percent of electrolytic copper, 0.3-1.5 percent of micro powder paraffin, 0.1-0.9 percent of easily cut agent and 0.1-0.9 percent of enhancer. The powder metallurgical formula consists of the following steps of mixing, pressing, sintering, fining, deburring and steaming. According to the powder metallurgical formula and technology, the tensile strength and the hardness of a product are improved; and by optimization of the technical steps, the production efficiency is improved, and the waste of energy is reduced.

Description

technical field [0001] The invention relates to the field of powder metallurgy, in particular to a powder metallurgy formula and process. Background technique [0002] Powder metallurgy is a process technology for producing metal or using metal powder as raw material, forming and sintering to manufacture metal materials, composite materials and various types of products. 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. However, the existing powder metallurgy formula and process still have limitations, and the many process steps lead to waste of energy and low production efficiency. At the same time, the product also has the problem of low tensile strength and hardness. Contents of the invention [0003] The invention proposes a powder metallurgy formula, which solves the problem of low tensile strength and hardness of products in the prior art. ...
