As we all know, titanium plate is a kind of highly corrosion-resistant metal materials, then how to produce the corrosion resistance of titanium plate? In the mysterious world of titanium, let us come to solve its mystery. Titanium is highly resistant to corrosion, so it is generally thought that it is a noble metal, but on the contrary, titanium is actually a very active metal,it has low equilibrium potential, in the medium, its thermodynamic corrosion tendency is big, but in a lot of media, titanium is very stable, such as in the oxidation, neutral weak and reduction medium. This is because titanium rods have a great affinity to oxygen, in the air or oxygen containing medium, titanium surface will generate a layer of dense, strong adhesion, large inert oxide film, it can protect the titanium substrate from corroding. Even if due to the mechanical wear and tear, it will soon be self-healing or re form oxide film. This point shows that titanium is a kind of metal with a strong passivation tendency, the medium temperature is at 315 degrees below, titanium oxide film has always maintained this characteristic.
