一、350/6拉丝机卷筒硼化处理 (一)硼化处理概述硼化是化学热处理方法之一。早在十九世纪末期就已经被认识并对此进行了尝试,但后来发展缓慢,落后于渗碳、氧化,主要因为国内、外硼化工艺本身还不够完善,对于其应用规律尚不清楚。近十几年来,随着科学的发展,渗硼工艺技术已较为成熟,因而获得广泛应用。按硼化时所用的介质不同,渗硼分为液体法、固体法和气体法三种。渗硼是借助热化学
A, 350/6 wire drawing machine boronization (a) Overview of boronization Boronization is one of the chemical heat treatment methods. As early as the end of the nineteenth century, it was known and tried. However, its slow development lagged carburizing and oxidation at the end of the nineteenth century. The main reason is that the domestic and external boronization process is not yet perfect, and its application law is not yet clear. In recent ten years, with the development of science, boronizing technology has been relatively mature, which has been widely used. Boron by the different media used, boron is divided into liquid law, solid and gas law three. Boronizing is by means of thermochemistry
