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. ˮƽÓÐÏÞ£¬½ö¹©²Î¿¼ |
