Wear corrosion is due to the medium velocity, relative velocity or medium and the metal member, causing the metal local surface subjected to severe corrosion damage, referred to as abrasion.
The liquid medium can be a gas, liquid, or a liquid containing solid particles, bubbles, etc.. Most of the metals and alloys are bound to suffer from this kind of corrosion damage.
The friction surface has material loss phenomenon called wear corrosion environment, referred to as abrasion.
Wear corrosion resistance refers to the accelerated corrosion damage of metal under the common action of wear and corrosion. The wear corrosion is different from the simple wear. The metal is dissolved in the form of metal ion instead of powder form. The main form of corrosion wear is micro vibration corrosion, turbulent corrosion and cavitation corrosion.
This kind of failure often wear corrosion current components in the pump, the valve over (pump body, impeller, seal ring, the inner wall of the pipeline and the surface), served in the corrosion medium (such as dynamic friction sealing surface and bearing parts), wear and tear caused by the flowing medium corrosion damage can be gas, liquid or solid particle and bubble liquid, the liquid solid two phase flow damage is particularly serious corrosion and wear associated with fluid motion, cavitation corrosion and erosion corrosion occurred in the friction surface corrosion wear and fretting corrosion etc..
Oxidative wear
Two, special medium corrosive wear
Three, cavitation erosion and wear
Four, fretting wear: mechanical fretting corrosion test, electromagnetic fretting corrosion test
