Application status of powder metallurgy in ceramic materials

Ceramic materials are mainly divided into ordinary ceramics and special ceramics according to different properties. Ordinary ceramics are ceramic materials made of clay and other materials sintered by traditional methods, which are generally brittle and fragile. Special ceramics are ceramic materials made of artificial compounds, such as oxides, nitrides, carbides and borides.

The difference between powder metallurgy process and casting process

The powder metallurgy process and the casting process are completely different. The powder metallurgy process is a sintering process, which is sintered through a sintering furnace and then finished. The casting process is a smelting process followed by pouring.

2024 powder metallurgy products process is what kind?

The process flow of powder metallurgy products is pulverized, molded, sintered and post-processed. The process flow of powder metallurgy products is as follows: 1. Preparation of raw material powder. At present, the milling methods can be divided into two categories: mechanical method and physical chemical method. Mechanical crushing and atomization methods are mechanical methods; physical and chemical methods are divided into: electrochemical corrosion method, reduction method, chemical method, reduction-chemical method, vapor deposition method, liquid phase deposition method and electrolysis method.

Comparison of advantages and disadvantages of powder metallurgy and foundry casting

Powder metallurgy is similar to the scope of foundry, foundry is strictly modeling casting, usually including sand casting and shell film casting. Generally speaking, the tensile properties of foundry castings and traditional powder metallurgy parts are the same as metal injection molded parts. The mechanical properties of powder metallurgy parts, especially the impact energy, are higher than those of foundry castings. The choice of which process often depends on the size of the part, and large parts should be manufactured by foundry casting.
