Adhesive Wear (Adhesive Wear) The two contact surfaces in relative motion produce solid-phase local welding or adhesive connection due to the attractive force between molecules, resulting in wear caused by the transfer of material from one surface to another surface, and Called adhesive wear.

Abrasive Wear: The two contact surfaces that move relative to each other are caused by the combination of micro-plowing, micro-cutting, and micro-cracking during the friction process of hard particles or micro-convex bodies on hard surfaces Scratches and surface materials fall off or separate out debris.

Fatigue Wear The two contact surfaces that roll or roll and slide against each other. Under the repeated action of alternating contact stress, due to fatigue of the surface material, micro cracks are generated and the abrasive or debris is separated and peeled off, resulting in pits. abrasion. Also called Pitting.

Corrosive wear (Corrosive Wear) metal surface in the friction process and the surrounding medium under the chemical and electrochemical reaction of the wear process.

Fretting wear caused by repeated oscillations of two contact surfaces with slight amplitude. Fretting wear is a kind of composite wear with both fatigue and corrosion.

Mild Wear The abrasive debris is very finely worn. Sometimes used to indicate wear under elastic contact.

Severe wear is the wear of larger fragments or particles. Sometimes used to indicate that the wear under plastic contact has been reached.

Normal wear (Normal Wear) design allowable wear

Material transfer (Pick-up or Transfer) The phenomenon of transferring material from one surface to another due to the strong adhesion of the sliding or rolling interface

Smearing The material on the surface of the friction pair is transferred and reapplied to one or both surfaces in a thin layer

Scratching (Scratching) is caused by local solid-phase "welding" or abrasion on the friction surface and causes tiny scratches or "plow marks" formed along the sliding direction.

Scoring is a serious scratch caused by the same reason as "scratch", also known as scratch

Scuffing solid surface "welding" of the two friction surfaces and the local damage, but no local surface fusion.

Seizure friction surface is severely adhered or transferred, so that the relative movement stops or can not move. Also known as bite sticky.

Selective Transfer (Selective Transfer) copper alloy has a special and extremely selective metal transfer effect on steel when it is rubbed in the boundary lubricants such as glycerin and triethanolamine that exclude copper oxidation. It is the phenomenon that copper is selectively transferred from the copper alloy to the steel and reversely transferred to the copper alloy. With the reduction of the friction coefficient, the wear is sharply reduced.

Oxidative wear (Oxidative Wear) wear when the friction surface interacts with oxygen to form a protective film.

Spalling: wear and tear that separates debris from the friction surface in the form of scales during fatigue wear

Erosive Wear (Erosive Wear) The fluid containing hard particles moves relative to the solid, causing the solid surface to be subjected to erosion. Also known as erosion (Erosion).

Fluid erosion (Fluid Erosion) due to the effect of liquid flow, air flow or air flow containing liquid beads

Cavitation Erosion (Cavitation Erosion) when the solid moves relative to the liquid, abrasion caused by the local high impact pressure or local high temperature when the bubbles in the liquid burst near the solid surface. Cavitation

Ploughing (Ploughing or Plowing) The relative movement of the softer surfaces of the two surfaces due to plastic deformation caused by plow marks. Plough

Wear Rate (Wear Rate) The ratio of the amount of wear to the travel or time of wear. There are usually three ways to express the wear rate: (1) the amount of material wear per unit sliding distance; (2) the amount of material wear per unit time; (3) the amount of material wear per revolution or per swing.

Wear resistance (Wear Resistance) The ability of materials to resist wear under certain friction conditions is evaluated by the reciprocal of the wear rate
