Abstract

The invention provides a powder metallurgy dissolving and infiltrating combination method, and relates to the field of powder metallurgy. The powder metallurgy dissolving and infiltrating combinationmethod comprises the following steps that S1, a raw material is prepared, specifically, a powder metallurgy material is selected according to a machined part, and then the material is put into a grinding machine to be ground; S2, workblank molding is carried out, specifically, metallurgical powder raw materials are placed in a forming mold, and a compression molding machine is used for pressing and forming a workblank; S3, sintering is carried out, specifically, the formed workblank obtained in the S2 is put into a sintering furnace to be sintered; S4, dissolving and infiltrating machining combination is conducted, specifically, the workblank subjected to heat treatment is put into a dissolving and infiltrating furnace to be combined with a dissolving and infiltrating agent to be subjectedto dissolving and infiltrating treatment. By means of a reasonable dissolving and infiltrating machining technology, the dissolving and infiltrating efficiency of parts is higher during dissolving and infiltrating machining, the technology is easy to machine and operate, the time needed in the machining process can be saved, and meanwhile rapid production of the parts is facilitated.

Description

technical field [0001] The invention relates to the technical field of powder metallurgy, in particular to a powder metallurgy dissolution and infiltration bonding 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. [0003] The processing of gears, bearings and rotating shafts by powder metallurgy is extremel...
