Can applying anti-rust oil to valve parts forgings prevent them from oxidation?

Applying anti rust oil can indeed effectively prevent valve parts forgings from being oxidized, especially during storage. Rust proof oil forms a protective film on the surface of metals to isolate oxygen and moisture in the air, preventing metal oxidation reactions. Here are several specific aspects to explain how rust proof oil prevents oxidation of valve parts forgings:

1. Isolate oxygen from the air: Oxidation reaction is the process by which metals react with oxygen in the air to produce oxides (such as rust). The oil film formed by rust proof oil completely covers the metal surface, reducing the contact between oxygen and metal and preventing oxidation reactions from occurring.
2. Moisture isolation: Moisture or moisture is an important factor in accelerating oxidation. The coating of anti rust oil can effectively isolate moisture in the air, prevent moisture from contacting the metal surface, thereby avoiding the corrosive effect of moisture on the metal and reducing the risk of rust.
3. Preventing contact with salt spray and chemical gases: For valve parts exposed to marine environments or chemical media, the coating of rust proof oil can effectively isolate the contact between corrosive gases such as salt spray and acid spray and metal surfaces. These corrosive substances are one of the main factors accelerating metal oxidation.
4. Reduce the impact of surface microcracks and pores: Small cracks and pores on metal surfaces are prone to oxidation, and rust preventive oil can fill these small defects to form a uniform protective film, thereby reducing the risk of oxide accumulation.
5. Delaying the occurrence of surface corrosion: Anti rust oil not only prevents oxidation, but also reduces the adhesion of surface pollutants such as dust, impurities, etc. These pollutants may accelerate local corrosion, and the coating of anti rust oil helps prevent these substances from damaging the metal surface.
6. Prevent condensation caused by temperature difference: When the temperature fluctuates greatly, condensation may occur on the metal surface, and water droplets may adhere to the surface, accelerating the oxidation process. Rust proof oil can prevent moisture from condensing on metal surfaces to a certain extent, further reducing the possibility of oxidation.
