一、前言某物体的硬度,可以表示为该物体对在外力作用下的另一物体所呈现的抵抗能力的大小。具体是,由于该物体的性质、形状与大小、发生变形的程度、抵抗能力的测定方法与表示方法而显示为不同的值。硬度的试验方法是多种多样的。在对岩石进行多种的试验中,将重点与机械钻探密切相关的研究结果整理如下,作为资料提供。在这里,对(1)压入硬度,(2)回跳硬度,(3)刻划硬度,(4)磨耗硬度进行分类解释。
I. INTRODUCTION The hardness of an object can be expressed as the resistance of the object to another object under the action of an external force. Specifically, it shows a different value due to the nature, shape and size of the object, the degree of deformation, and the method of measuring and displaying the resistance. The hardness test methods are varied. In a variety of tests on rocks, the results of studies closely related to mechanical drilling are summarized below and provided as data. Here, (1) press into the hardness, (2) rebound hardness, (3) engraving hardness, (4) wear hardness classification explained.
