1、序言有一系列钢材,但也有其它材料可用于制造块规,可是,根据多年的试验研究和经验,一般称为轴承钢的,那种含1%C 和1.5Cr 并含少量V 或Mo 添加物的钢材被认为是最合适的材料。许多研究人员都以尺寸稳定性和耐磨损性为着眼点对块规和高级精密仪器零件的热处理最佳化进行了试验研究。虽然如此,这个问题在当前还是具有重要意义的,这是因为随着技术的发展对量具的要求也提高了,例如美国有一些工业部门在最近几年内,将块规的允
1. Introduction There is a series of steels, but there are other materials that can be used to make block gauges, however, based on years of experimental research and experience commonly referred to as bearing steels, those containing 1% C and 1.5 Cr with minor amounts of V or Mo addition Material steel is considered the most suitable material. Many researchers have studied the optimization of heat treatment of block gauges and high precision instrumentation components with the focus on dimensional stability and wear resistance. Nevertheless, this issue is still of great significance at present, because the demand for gauges has been raised with the development of technology. For example, some industrial departments in the United States, in recent years,
