delamination wear 是什么意思？

机理是什么？

delamination wear：剥层磨损，以下是英文解释：
Delamination wear is an extension of the surface fatigue wear case with the surface fatigue applying over a larger surface area. Whereas the surface fatigue case reacted to damage caused by solid contamination interfering with the surface lubrication, delamination does not require outside influences. Surfaces in constant contact with each other due to incorrect or inefficient lubrication will stress harden and case sub-surface deformation which would ultimately result in cracking. Further adhesive wear could eventually lift flat fragments from the surfaces affected. Microscopically the particles will appear as flake-like in shape with striations over the surface due to the adhesive wear.
