The three major antirust treatment methods of powder metallurgy are very useful! The processing technology of powder metallurgy is an amazing processing technology for Xiaobian. Through the processing of powder metallurgy, it can be made into metal materials, composite materials and various types of products. So what exactly is it for anti-rust treatment, don't worry, take a look with the editor!
1: Use anti-rust oil. Anti-rust paper for anti-rust treatment
After the processing of powder metallurgy parts is completed, apply appropriate anti-rust oil and carry out anti-rust paper packaging for anti-rust. In order to avoid rusting of the product during transportation and storage, it must be kept in a sealed state and not damp. The use of anti-rust oil has certain requirements for storage and transportation! To ensure the anti-rust effect, the workpiece will not rust!
2: Passivation, coating treatment
Passivation and coating treatment, rust prevention is still required during transportation, and coating has an impact on later assembly use. The anti-rust effect of this method is general, and the anti-rust time is not very long. If the anti-rust requirements are strict, it is possible to apply anti-rust oil for anti-rust!
3: Use antioxidants
Anti-rust treatment methods for iron-based powder metallurgy products and other surfaces can use antioxidants. After use, stir or shake the uniform solution before use, immerse or spray on the metal surface to dry (dry).
