水钉的作用，使土钉体外表面与土体界面接触粘结力与摩擦阻力显著降低。
By action of water to nail, Bond between soil and nail a was obviously reduced.
由于蠕变和应力松弛的影响，粘结层应变不可逆地增加，使TGO层的界面形貌出现起伏。
Impacted by creep and stress relaxation, the strain of bond coat layer increases irreversibly, and the TGO layer convolutes .
涂层剥落后，切削区产生的瞬时热量聚集使基体粘结相软化，从而导致硬质相颗粒脱落和基体的剧烈磨损。
After the coating broke off, the instantaneous heat builds up and softens the substrate's bonding phase, which results in breaking off of hard phase particles and sharp wear of substrate.
