How does the principle of corrosion resistance of titanium plate come about?

As we all know, titanium plate is a kind of metal material with great corrosion resistance? So how exactly is the corrosion resistance of titanium produced? In the mysterious titanium world, let us solve its mysteries one by one. Titanium plus tool corrosion resistance, so everyone usually thinks it is an inert metal, but on the contrary, Molybdenum Sputtering Target is actually a very active metal, its equilibrium potential is very low, and the thermodynamic corrosion tendency in the medium is large, but in fact, Titanium is very stable in many media. For example, Grade 7 Titanium Plate is corrosion-resistant in oxidizing, neutral, and weakly reducing media.

This is because the titanium rectangular rod has a great affinity with oxygen. In the air or in an oxygen-containing medium, a dense, strong adhesion and inert oxide film will form on the surface of the titanium, which protects the titanium matrix from corrosion. Even due to mechanical wear, it will quickly heal itself or regenerate an oxide film. This indicates that titanium is a metal with a strong tendency to passivation, and the titanium oxide film always maintains this characteristic when the medium temperature is below 315℃.
