[求助] 3句话,实在翻译不下去了,求帮忙,谢谢虫友

1 在接触应力作用下,速度增加容易在缺陷处萌生裂纹或加快已存在裂纹的扩展,导致涂层出现层片剥落
2 速度较低时,涂层表面某些层间结合较差的薄弱区域由于“粘着效应”而剥落,涂层表面的“转移膜”较好的保护了涂层本身,层片剥落不明显,磨损量较小。
3 随着速度的增加,涂层内部裂纹的形成速度和扩展速度随之增加,当这些裂纹汇合后,涂层成片状剥落下来,并且这种剥落会诱发周围涂层的剥落,磨损量较大

With the effect of contact stress, the increasing  speed produces  initiation crack or speeds up the expansion of the existing crack  in defect ,which will lead to a coating layer peeling off.
At low speeds, some poor interlayer combined with the weak area of coating surface will peel off due to the "sticky effect", and "the transfer film" on the  coating  surface  protects the coating itself well, so that the layer peeling is not obvious and makes small wear
With the increasing speed, the  formation and the extension speed of coating internal crack    increases,  after the crack converges, coating is peeling off with the slice shape, which can induce the peeling coating spalling in surrounding, and the wear volume is bigger.
水平有限,仅供参考
