Tooth Plate Rough PM Sintered Parts
I believe everyone knows that powder metallurgy can only be manufactured through a series of processes such as powder production, pressing, sintering, and post-processing. Among them, powder metallurgy sintering is a high-temperature treatment process that further combines compacts or loose powder bodies, and Tooth plate rough PM sintered parts to improve strength and other properties. However, due to different requirements, powder metallurgy sintering methods are also divided into many types.

I believe everyone knows that powder metallurgy can only be manufactured through a series of processes such as powder production, pressing, sintering, and post-processing. Among them, powder metallurgy sintering is a high-temperature treatment process that further combines compacts or loose powder bodies, and Tooth plate rough PM sintered parts to improve strength and other properties. However, due to different requirements, powder metallurgy sintering methods are also divided into many types.
Powder metallurgy sintering method
1. Liquid phase sintering
If there are more than two components in the powder compact, sintering may be carried out above the melting point of a certain component, so a small amount of liquid phase appears in the powder compact during sintering.
2. Pressure sintering
During sintering, pressure is applied to the powder body to facilitate its densification process. Pressure sintering is sometimes synonymous with hot pressing. Hot pressing is a process that combines powder forming and sintering to directly obtain products.
3. Activation sintering
Some physical or chemical measures are adopted in the sintering process so that the sintering temperature is greatly reduced, the sintering time is significantly shortened, and the performance of the sintered body is improved and enhanced.
4. Electric spark sintering
The powder body is fed with direct current and pulse power during forming and pressing so that an arc is generated between the powder particles and sintered; during sintering, pressure is gradually applied to the workpiece, and the two processes of forming and sintering are combined together.
The content introduced above is the four common powder metallurgy sintering methods. Through these sintering methods, the powder metallurgy sintering process can be effectively completed. Because, in the powder metallurgy sintering process, the powder particles have to undergo physical and chemical processes such as mutual flow, diffusion, melting, and recrystallization, so that the powder body is further compacted and some or all of the pores are eliminated.
