Quantitative evaluation of scratch-induced damages on polymeric and coating materials
摘要
<p>Provided is a method for quantitative evaluation of mar- and scratch-induced surface damage on polymeric and coating materials. The method for quantitative evaluation of scratch-induced damage on polymeric and coating materials includes: preparing a test specimen of polymeric and coating materials; inducing a scratch damage on the surface of the test specimen; representing the scratch damage formed on the test specimen as corresponding color coordinates; and calculating a quantitated scratch damage index from a combination of a load applied to the surface of the test specimen and the color coordinates corresponding to the scratch damage.
