硬度的概念

简单来说,铁钉子可以钉入木头是因为铁比木头硬,将另一物体向某一物体表面压入时,该物体的抵抗能力就是硬度。归结到定义就是材料通过永久塑性变形抵抗外加载荷的强度性能。


硬度测试的分类

科学家根据硬度的原理将测试分为两大类:划痕硬度和压入硬度。在之前文章中所讲的布氏、洛氏、维氏等硬度是压入硬度;划痕硬度,则是用不同硬度的铅笔划待测物体表面,进而测试出产品的硬度值。

根据GB/T 6739-2006 色漆和清漆 铅笔法测定漆膜硬度的标准要求,规定了用已知硬度的铅笔,测定涂层表面相对硬度的方法。铅笔的硬度,H(hardness)表示,B=BLACK(黑度),H=HARD(硬度),B数越多铅笔就越黑越软,H数越多就越硬颜色越浅。
