QUANTIZATION METHOD FOR SCRATCH-INDUCED SURFACE DAMAGE ON POLYMERIC AND COATING MATERIALS

摘要

PROBLEM TO BE SOLVED: To provide a method for quantitative evaluation of mar- and scratch-induced surface damage formed on polymeric and coating materials.

SOLUTION: A quantization method for scratch-induced surface damage on polymeric and coating materials includes the following steps: 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 surface of the test specimen by a corresponding color coordinate, and calculating a quantitated scratch damage index by combining the weight applied on the surface of the test specimen and the color coordinate corresponding to the scratch damage.
