Powder metallurgy has three major surface anti-rust treatment methods to help products rust . The process of powder metallurgy is a very magical process and technology. Through the process of powder metallurgy, metal materials, ceramic materials, composite materials and various complex types of products can be made. So what exactly does it do to prevent rusty? Please see the following three ways.
Metal injection molding is a branch of traditional powder metallurgy, which is more refined. Of course, it also applies to the following three anti-rust methods.
1: Use anti-rust oil and anti-rust paper for anti-rust treatment
After the processing of powder metallurgy parts, appropriate antirust oil shall be applied, and antirust paper shall be used for antirust packaging. During transportation and storage, the product shall be kept in a sealed state and free from moisture in order to avoid rusting. The usage of antirust oil has certain requirements for storage and transportation. Ensure the anti-rust effect, and the workpiece will not rust.
2: Passivation, coating treatment
For passivation and coating treatment, rust prevention is still required during transportation, and coating has an impact on later assembly and use. The antirust effect of this method is general, and the antirust time is not very long. If the antirust requirements are strict, it is possible to apply antirust oil for antirust.
3: Use antioxidants
The surface anti-rust treatment methods such as iron-based powder metallurgy products can use antioxidants. Before use, stir or shake the uniform solution, and then immerse or spray it on the metal surface to dry (dry).
