一、硬质合金在近代工业上的应用随着机器制造工业的发展,对寻求高强度的金属材料,就显得特别需要了。在很大程度上,硬质合金材料的机械-物理性能大大超过了其他工程材料,因而它已成为近代机器制造工业上广泛应用的重要材料之一。硬质合金的特点是具有高的硬度、耐热性及耐磨性,故首先被广泛应用在机器制造工业上来制造各种车、鲍、鉆、銑、鏜等金属切削刀具。这些刀具一般都由两部分组成,一部分是用一般材料制成的刀具体(如鋃齿铣刀的刀盘体、普通切刀的
First, the application of cemented carbide in modern industry With the development of the machine-building industry, it is particularly necessary to seek high-strength metal materials. For the most part, the mechanical-physical properties of cemented carbide materials surpass those of other engineering materials, so it has become one of the most important materials widely used in modern machinery manufacturing industry. Carbide is characterized by high hardness, heat resistance and wear resistance, it is first widely used in the machinery manufacturing industry to create all kinds of cars, abalone, drilling, milling, boring and other metal cutting tools. These knives are generally composed of two parts, one part is made of general-purpose tool body (such as the cutter body cutter body, the common cutter
