Automotive paint susceptible to scratches makes it difficult and costly to maintain and repair. Different coating architectures of the primer, basecoat, and clearcoat have been developed to achieve the best scratch/mar resistance. Nanoscratch testing has been […]

]]> 根据ASTM D7187标准，油漆的抗划伤性和抗污性在其最终用途中起着至关重要的作用。易受划痕影响的汽车漆在维护和修理方面很困难，而且成本很高。为了达到最佳的抗刮伤/抗污能力，人们开发了不同的底漆、基底漆和清漆的涂层结构。 纳米划痕测试 已经开发出一种标准的测试方法，用于测量油漆涂层的划痕/破坏行为的机械方面，如ASTM D7187中所述。.在划痕试验中，不同的基本变形机制，即弹性变形、塑性变形和断裂，在不同的载荷下发生。它提供了对油漆涂层的抗塑性和抗断裂性的定量评估。
