Problems solved by technology

[0003] However, there are problems such as low permeability, large density fluctuations, and difficult to clean residues during copper infiltration and sintering on the market, resulting in poor mechanical properties and wear resistance; in addition, the current penetrating agent is mainly in the powder state, and the powder is in the water atomization preparation process. Medium, easy to oxidize, high production cost, complicated process, which largely limits the development of high-end powder metallurgy preparation

Description

technical field [0001] The invention relates to the technical field of metallurgical copper infiltration, in particular to a method for preparing a high infiltration rate copper infiltration wire. Background technique [0002] Powder metallurgy iron-based products are widely used because of their high material utilization rate, high dimensional accuracy, and less processing steps. In powder metallurgy iron-based products, the wear resistance of powder metallurgy products can be significantly improved by copper infiltration process. Therefore, high-grade powder metallurgy iron-based products will be copper infiltrated when sintering the green body. [0003] However, there are problems such as low permeability, large density fluctuations, and difficult to clean residues during copper infiltration and sintering on the market, resulting in poor mechanical properties and wear resistance; in addition, the current penetrating agent is mainly in the powder state, and the powder is i...
