Term explanation: What is wear corrosion (abrasion)? Under the impact of high-speed fluids, the destructive effects of both wear and corrosion on metal surfaces are referred to as wear corrosion. ====================================== Promotion event: Petrochemical sector – “Creative Ideas for Energy Savings” campaign (the second phase is currently in progress). http://bbs.hcbbs.com/thread-1666758-1-1.html (Source: Haichuan Chemical Industry Forum) 2017 Coal Chemical Industry – “My Technical Upgrades”. http://bbs.hcbbs.com/thread-1786290-1-1.html (Source: Haichuan Chemical Industry Forum)
It refers to the phenomenon of material loss that occurs when, during relative sliding between the mating surfaces of a friction pair, the surface material undergoes chemical or electrochemical reactions with the surrounding medium, along with mechanical effects.
The destructive phenomenon in which fluid flow, under high-speed impact, causes both wear and corrosion on a metal surface is known as wear corrosion
It refers to the wear phenomenon in which, in a corrosive medium, chemical or electrochemical reactions occur between the friction surface and the medium, resulting in material loss
Corrosive wear refers to the phenomenon of material loss that occurs when, during relative sliding between the mating surfaces of a friction pair, the surface material undergoes chemical or electrochemical reactions with the surrounding medium, along with mechanical action. Corrosive wear is usually a mild form of wear, but under certain conditions it can also turn into severe wear. Common forms of corrosion wear include oxidative wear and corrosion wear caused by specific media.
Due to the relative movement between the corrosive medium and the metal surface. It causes accelerated degradation and wear of metals. It generally acts in conjunction with mechanical wear to cause corrosive damage that results in pits, grooves, and ripples on the metal surface.
Wear caused by the direct impact on container components when a medium containing solid particles flows within the container.
The relative movement between the corrosive medium and the metal surface causes accelerated degradation and abrasion of the metal.
The loss of material from the friction surface in corrosive environments is known as wear corrosion
Under normal conditions, this does not happen; however, if the protective layer is damaged due to prolonged exposure or abnormal conditions, corrosion will occur.
