Adhesive wear is a kind of wear caused by the transfer of materials from one surface to another surface due to the attraction between molecules to produce solid-phase local welding or adhesive connection between two contact surfaces that are in relative motion. called adhesive wear.

Abrasive wear (Abrasive Wear) The surface caused by the combined action of "micro-ploughing", "micro-cutting" and micro-cracking of hard particles or micro-convex bodies on a harder surface in the process of friction Scratches and surface material come off or separate out wear debris.

Fatigue wear (Fatigue Wear) Two contact surfaces that roll or roll and slide with each other. Under the repeated action of alternating contact stress, due to the fatigue of the surface material, microscopic cracks are generated, and abrasives or fragments are separated and peeled off, forming pits. wear. Also known as pitting (Pitting).

Corrosive wear is the wear process of the metal surface under the action of chemical and electrochemical reactions with the surrounding medium during the friction process.

Fretting is the wear caused by the repeated oscillation of the two contact surfaces with small amplitudes. Fretting wear is a composite wear in which driven fatigue and driven corrosion coexist.

Mild Wear is very fine wear. Sometimes used to indicate wear under elastic contact.

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

Normal wear (Normal Wear) Design allowable wear and tear

Material transfer (Pick-up or Transfer) The phenomenon in which material is transferred from one surface to another due to strong adhesion at the sliding or rolling interface

Smearing Transfer of material on one surface of the friction pair and re-applying in a thin layer to one or both surfaces

Scratching is the tiny scratches or "ploughs" formed along the sliding direction caused by the "welding" or wear of the local solid phase on the friction surface.

Scratching (Scoring) Severe scratches formed by the same cause as "scratch", also known as scratches

Scuffing The solid-phase "welding" of the two friction surfaces causes local damage, but no local surface fusion occurs.

Seizure: Severe adhesion or transfer of the friction surface, so that the relative movement stops or cannot be moved. Also called biting.

Selective Transfer is a special and extremely selective metal transfer effect of copper alloys on steel when they are rubbed in boundary lubricants such as glycerol and triethanolamine that exclude copper oxidation. It is the phenomenon of selective transfer of copper from copper alloys to steel and back to copper alloys, accompanied by a decrease in the coefficient of friction and a dramatic reduction in wear.

Oxidative wear is the wear when the friction surface interacts with oxygen to form a protective film.

Spalling is the wear in which wear debris is separated from the friction surface in the form of flakes during fatigue wear

Erosive wear is the wear caused by the movement of the fluid containing hard particles relative to the solid, causing the solid surface to be eroded. Also known as erosion (Erosion).

Fluid Erosion Wear due to the action of liquid flow, air flow or air flow containing liquid beads

Cavitation Erosion is the wear caused by local high impact pressure or local high temperature when the solid moves relative to the liquid due to the rupture of bubbles in the liquid near the surface of the solid. Also called cavitation

Ploughing or Plowing is a plough-mark-like failure formed by plastic deformation of the softer surface of the two surfaces in relative motion. plow crease

Wear Rate The ratio of the amount of wear to the stroke or time of wear. Generally, the wear rate can be expressed in three ways: (1) the material wear amount per unit sliding distance; (2) the material wear amount per unit time; (3) the material wear amount per revolution or per swing.

Wear Resistance (Wear Resistance) The ability of a material to resist wear under certain friction conditions, which is evaluated by the inverse of the wear rate
