Advantages and disadvantages of powder metallurgy process?

Powder metallurgy mainly uses metal powder as raw material, and makes it into the shape we need through certain processing technology. This processing technology is very similar to the production of ceramics. Therefore, a series of powder metallurgy technologies can also be used for the preparation and production of ceramic materials. This article will specifically introduce the relevant knowledge of powder metallurgy technology, and understand the advantages and disadvantages of powder metallurgy technology. It is provided by ABCDprecision.

What are the advantages and disadvantages of powder metallurgy technology

一、 Advantages of powder metallurgy process

1. Special materials can be processed. The method of material powder metallurgy can produce refractory metals, compounds, false alloys and porous materials.

2. Save metal and reduce cost. Because powder metallurgy can be pressed into final size compacts, there is no need to use machining. The loss of metal produced by this method is only 1-5%, while the general processing will consume 80% of the metal.

3. Prepare high-purity materials. The powder metallurgy process does not melt materials in the material production process, so it will not be mixed with impurities brought by other substances. The sintering is carried out in vacuum and reducing atmosphere, so there is no fear of oxidation and no material pollution. Therefore, the purity of the product is relatively high.

4. Correctness of material distribution. The powder metallurgy method can ensure the correctness and uniformity of the material composition in the proportion.

5. Mass production reduces costs. Powder metallurgy is suitable for the production of products with a large number of uniform shapes, such as gears and other expensive products, which can greatly reduce production costs.

二、 Disadvantages of powder metallurgy process

1. Powder metallurgy products have poor strength and toughness. As the internal pores of compacts made of powder cannot be completely eliminated, the strength and toughness of powder metallurgy products are inferior to those of castings and forgings with corresponding components.

2. Powder metallurgy cannot be made into large products. Since the fluidity of metal powder is worse than that of liquid metal, its shape and size will be limited to a certain extent, and its weight will not exceed 10kg.

3. The die cost is high. Because the cost of die manufacturing is too high, it is only suitable for mass production.

三、 Development of powder metallurgy products

1. High quality structural parts: the representative of powder metallurgy is iron base alloy, which will develop into high-volume precision products and high-quality structural parts.

2. High performance alloy: High performance alloy with uniform microstructure, difficult to process and completely dense made by powder metallurgy.

3. Mixed phase special alloy: powder metallurgy uses an enhanced densification process to produce special alloys that generally contain mixed phases.

4. Composite parts: composite parts with unique and unusual shape or composition.
