Exploring the secrets of machining passivation technology: the "invisible armor" that protects metals

Application scenarios

1. Aerospace: Passivation is often used in key parts such as blades and landing gear of aircraft engines to improve their corrosion resistance and oxidation resistance in complex high-altitude environments to ensure flight safety.

2. Automobile manufacturing industry: Passivation treatment of engine parts, exhaust system parts, etc. of automobiles can enhance their corrosion resistance, extend their service life, and reduce failures and maintenance costs caused by corrosion.

3. Electronic and electrical industry: Passivation treatment of pins and circuit boards of electronic components can prevent rust and oxidation in humid or chemical environments, ensuring the performance stability and reliability of electronic equipment.

Function and significance

1. Improving corrosion resistance: This is the most important role of the passivation process, which can significantly extend the service life of metal parts and reduce equipment failures and replacement costs caused by corrosion.

2. Improving appearance quality: The passivated metal surface is usually smoother, more uniform, and has a consistent color, which can improve the appearance quality of the product and enhance the market competitiveness of the product.

3. Enhancing surface hardness: Some passivation processes can improve the hardness of the metal surface to a certain extent, thereby improving its wear resistance and scratch resistance, so that the parts can better maintain surface integrity during use.
