Stainless steel "target=_blank> stainless steel, cobalt, chrome alloy and other surface passivation film is destroyed in the end face friction, under the condition of anoxic, the new film is difficult to generate, which makes the galvanic corrosion intensified.

Second, stress corrosion cracks. Under the action of corrosion and tensile stress, the metal firstly produces cracks in the weak area, and then develops into the depth, causing cracking, called stress corrosion cracking. The hardfacing alloy and the sealing ring such as cast iron, tungsten carbide and titanium carbide are used. Stress corrosion cracking is prone to occur. The seal ring cracks are generally radially divergent and may be one or more. These cracks communicate the entire sealing end face, accelerating the wear of the end face and increasing the amount of leakage.
