What are the factors that affect the corrosion resistance of vacuum components?

The metal element that affects the corrosion resistance of vacuum components is chromium. When the chromium content in the vacuum components reaches 10.5%, its atmospheric corrosion resistance increases significantly. This value is also a bottleneck, even if the chromium content is higher than 10.5%, the corrosion resistance does not increase significantly. The reason why chromium can affect the corrosion resistance of vacuum components is that when steel is alloyed with chromium, a tightly adhered chromium-rich oxide protective surface is formed on the surface of vacuum components, which can prevent further oxidation of vacuum components. . Even if this protective layer is damaged, it can repair itself and play a protective role again. Therefore, the vacuum components we use are usually added with chromium, so that the content reaches 10.5%, to achieve corrosion resistance.
