随着对强化重载齿轮需要量的增长,制造厂日益将注意力转向渗碳。但设计师和热处理工作者在这方面往往没有共同语言。作为设计师,总是力求使用较小而又经济的零部件来获得较高的承载能力。为此,他们更加信赖渗碳齿轮,以使得到更高的强度和耐久性。工业上,渗碳正在代替简单的淬火和回火、感应淬火及火焰淬火,并且正以8620、4620、4320、4820、9310和3310等渗碳钢代替旧的代用钢,如1045、4140、 As demand for hardened heavy-duty gear grows, manufacturers increasingly turn their attention to carburizing. But designers and heat-treatment workers often have no common language in this regard. As a designer, always try to use smaller and economical parts to get higher carrying capacity. To this end, they rely more on carburizing gears to achieve higher strength and durability. In industry, carburizing is replacing simple quenching and tempering, induction hardening and flame hardening, and is replacing the old alternative steels with 8620, 4620, 4320, 4820, 9310 and 3310 iso-carburized steels such as 1045, 4140,
