Classification of adhesive wear in mechanical seal applications:

(1) Smearing a phenomenon in which the material on one surface (usually a material that will soften or melt) migrates and is reapplied to one or two surfaces in a thin layer. For example, the material of the copper ring of the mechanical seal is coated on the surface of the steel ring.

(2) Scratching is caused by local solid phase welding on the surface, which is caused by fine scratches along the sliding direction.

Phenomena.

(3) Scoring is a phenomenon in which serious scratches are formed along the sliding direction caused by the local solid phase welding of the clothes curve.

(4) Scuffing has local damage caused by solid phase welding between the two sliding surfaces, but local fusion welding has not yet occurred.

(5) Seizure is caused by the friction of the interface causing the surface to be welded and the relative movement of the surface stops. This surface welding is caused by the adhesion between solid surfaces. When seizure occurs, the strength of the bonding point is quite high, and the instantaneous flash temperature on the surface is also quite high. Therefore, the adhesion area is large, and the strength of the bonding point is quite high. The bonding point cannot be cut off from the substrate, so that the relative movement is forced to stop.　　382.html,
