WebNov 25, 2024 · Generally, according to the different failure degree of coating, Lc can be defined as follows: Lc1 corresponds to the critical load of cohesive failure of the coating; … WebDuring the test the coefficient of friction µ was recorded. Applied loads were in the range between 10 N and 80 N. After the scratches were made, the tracks were examined with optical microscopy. A second critical load Lc2 was obtained from the scratch tests with constant load. Lc2 indicates complete coating removal inside the track.
