对于高强度齿轮的需要增长时,制造厂家越来越趋向于渗碳——但是设计者及热处理工作者并不总是都有共同的语言。因为变速箱设计者设法制造出较高功率容量而又体积较小、更经济的标准部件,所以他们就更加信赖渗碳齿轮,以获得较高强度和耐用度。在整个工业中,渗碳正在代替简单的淬火与回火、感应淬火和火焰淬火。渗碳钢象8620、4620、4320、4820、9310和3310正在代替以往的主要的材料象1045,4140和4340。假如工程师设计一种大批量生产的零件,并且可以使用到适当的试验装置上,对于一个
As the need for high-strength gears grows, manufacturers tend to carburize more and more - but designers and heat-treating workers do not always have a common language. Because gearbox designers are trying to create smaller and more economical standard parts of higher power capacity, they are placing greater emphasis on carburized gears for greater strength and durability. Throughout the industry, carburizing is replacing simple quenching and tempering, induction hardening and flame hardening. Carburizing steels like the 8620, 4620, 4320, 4820, 9310 and 3310 are replacing the main materials of the past like 1045, 4140 and 4340. If an engineer designs a mass-produced part that can be used on a suitable test rig,
