Abstract

The invention provides a powder metallurgy dissolution and bonding method, which relates to the field of powder metallurgy. The infiltration bonding method of powder metallurgy includes the following steps: S1. Raw material preparation: select powder metallurgy materials according to the processed parts, and then put the materials into the grinder for grinding treatment, S2. Blank forming: use the metallurgical powder raw materials in S1 Placed in a forming mold, and then pressed and formed using a press molding machine, S3. Sintering treatment: put the formed blank obtained in S2 into the interior of the sintering furnace for sintering treatment, S4. Infiltration processing combination: heat treatment The blank is put into the interior of the infiltration furnace and combined with the infiltration agent for infiltration treatment. Through reasonable infiltration processing technology, the infiltration efficiency of parts is higher during infiltration processing, and the processing operation of this process is simple, which can save the time required in the processing process and is conducive to the rapid production of parts.

Description

A kind of powder metallurgy solution infiltration bonding method technical field [0001] The present invention relates to the technical field of powder metallurgy, in particular to a method for infiltration and infiltration of powder metallurgy. Background technique Powder metallurgy is to prepare metal powder or use metal powder (or mixture of metal powder and non-metal powder) as It is a process technology for manufacturing metal materials, composite materials and various types of products after forming and sintering as raw materials. powder metallurgy The gold method is similar to the production of ceramics, and both belong to the powder sintering technology. Therefore, a series of new powder metallurgy technologies are also available. for the preparation of ceramic materials. Due to the advantages of powder metallurgy technology, it has become the key to solving the problem of new materials. plays an important role in the development of [0003] The processing o...
