Specimen Preparation
Model 463
463 型 Sikkens 划痕笔由硬金属刀刃和侧面支撑头和手柄形式的导轨组成。在型号 463 的标准版本中，刀刃宽度为 1 mm，矩形边缘。借助调整螺丝对齐刀刃，使其与支撑头对齐（参见图 2）。根据要求也可提供 0.5 mm 宽的硬金属刀刃。
目的和应用。刮针法用于在涂层测试板上产生确定的损伤（裂纹），以用于腐蚀测试，例如，根据DIN EN ISO 9227标准，使用ERICHSEN腐蚀测试仪器606和608型进行雾喷测试。这种方法为评估涂层下的腐蚀程度或影响及其对附着力的影响提供了一个标准。涂层下的横向损伤的长度可作为腐蚀保护系数的衡量标准。
设计和功能。Sikkens的463型划痕测针由一个硬质合金切割刀片组成，由一个支撑旋钮和一个手柄引导。在463型的标准版本中，切割刀片的宽度为1毫米，边缘呈矩形。它可以在水平方向上通过使用锁紧螺钉提高或降低切割刀片进行调整。根据要求，还可以提供0.5毫米的硬质合金切割刀片。
测试的执行。测试板在整个金属板的宽度上准备了一条或几条直的划痕，其方式是与金属板的窄边平行，并穿透到基材上。在某些情况下，可能需要一个圣安德鲁十字形的划痕。
