摘　　要：油漆喷涂作为一种金属材料的表面防腐处理工艺,由于其优秀的防腐/防老化性能、低廉的成本以及工艺简单,在日常生活和工业生产领域得到广泛应用。在一些恶劣的应用场景中,当表面油漆受到划痕、碰撞、摩擦和外部物体的冲击等物理影响时,可能会导致开裂、脱落等损坏,暴露底层金属基材,失去对基材的保护作用,降低产品的使用寿命。在油漆等表面处理的抗划痕检测标准中,测试后是否暴露基材的评价方法主要基于标准光源下的目视观察。在实践中,通过肉眼进行主观判断是非常困难的,也可能引起争议和质疑。本文以油漆喷涂金属件表面耐刮擦试验后的结果评价方法为出发点,详述了耐刮擦试验后对结果评价方法的选择和介绍,并对这些方法进行分析和探讨。As a surface anti-corrosion treatment process for metal materials,painting has the most extensive applications in today's social life and production due to its excellent anti-corrosion/aging performance,low cost,and simple process.In some harsh application scenarios,when the surface paint is subjected to physical effects such as scratches,collisions,friction,and impacts from external objects,it may cause cracking,detachment,and other damage to the surface paint,exposing the underlying metal substrate and losing its protective effect on the substrate,reducing the product's service life.In the testing standards for scratch and scratch resistance of surface treatments such as painting,the evaluation methods for whether it is exposed substrate after testing are mostly based on visual observation under standard light sources.In actual practice,subjective judgment through the naked eye is very difficult,and may also cause controversy and questioning.This article takes the evaluation methods of the results after the scratch resistance test on the surface of painted metal parts as the starting point,elaborates on the selection and introduction of the evaluation methods for the results after the scratch resistance test,and analyzes these methods.
