Mechanisms of blistering and chipping of a scratch-resistant coating

Scratch hardness as a quasi-intrinsic parameter to measure the scratch resistance of polymers

“…ductile ploughing or brittle machining), again they cannot easily provide quantitative evidence of the performance exhibited by different materials. In a similar way, studies focused on post-scratch analysis of the residual scratch grooves [21,[28][29][30], conducted using a variety of microscopy, diffractometry or spectroscopy techniques, can help in identifying the ongoing mechanisms. They can help to explain why a given material performs in a certain way; however, they do not offer a true measurement of the scratch resistance.…”

Stone-chipping and adhesion deterioration of automotive coating systems caused by outdoor weathering of underneath layers

“…layers of automotive coating system [10,[16][17][18][19][20]. In a domestic car manufacturer, preliminary investigations revealed that car bodies which had experienced outdoor deposition during their painting process had inferior chipping performance compared to those had regular painting process (no weathering exposure).…”
