					<description><![CDATA[<p>HIGH TEMPERATURE SCRATCH HARDNESS USING A TRIBOMETER Prepared by DUANJIE, PhD INTRODUCTION Hardness measures the resistance of materials to permanent or plastic deformation. Originally developed by a German mineralogist Friedrich Mohs in 1820, scratch hardness test determines the hardness of a material to scratches and abrasion due to friction from a sharp object1. The Mohs&#8217; [&#8230;]</p>

									<p>硬度衡量的是材料对永久或塑性变形的抵抗力。划痕硬度测试最初是由德国矿物学家弗里德里希-莫尔斯在1820年开发的，它确定了材料对尖锐物体的摩擦造成的划痕和磨损的硬度。<sup>1</sup>.莫氏标度是一个比较指数，而不是一个线性标度，因此，ASTM标准G171-03所述，开发了一个更准确和定性的划痕硬度测量方法。<sup>2</sup>.它测量金刚石测针产生的划痕的平均宽度并计算出划痕硬度数（HSP）。</p>								</div>

									想象一下，一个散装样品以恒定的速度均匀地被加热的情景。当散装材料加热并接近其熔点时，它将开始失去其刚性。如果在相同的目标力下进行周期性压痕（硬度测试），每次压痕的深度应该不断增加，因为样品正在变软（见图1）。这种情况一直持续到样品开始融化。在这一点上，每个压痕的深度将被观察到大幅增加。利用这个概念，材料的相变可以通过使用固定力振幅的动态振荡和测量其位移来观察，即动态机械分析（DMA）。
