感应热处理的零件与一般热处理的零件相比,可得到更细密的组织、较高的硬度和更理想的压应力分布,因而具有较高的耐磨性和静载、动载强度。此外,由于感应热处理可取代一部分渗碳和调质工艺,因而又具有节能、快速和无污染等优点,符合可靠(sure)、安全(safe)、节约(saving)的三 S 标准,及低温(cool)、干净(clean)、安静(calm)的三 C 标准。鉴于此,其发展势头五十年来有增无减。从美国1979年公布的一份资料(见表1)来看,八十年代,感应热处理仍然是富有成效的先进热处理工艺之一。据专家们预测,到本世纪末,
Induction heat treatment of parts compared with the general heat treatment, can be more dense tissue, higher hardness and more ideal compressive stress distribution, which has high wear resistance and static load, dynamic load strength. In addition, since induction heat treatment replaces a part of carburizing and quenching processes, it also has the advantages of energy saving, quickness and no pollution, meets the S standards of safe, safe, and low temperature cool, clean, calm three C standard. In view of this, the momentum of its development has been increasing for 50 years. According to a report released by the United States in 1979 (see Table 1), induction heat treatment was still one of the fruitful and advanced heat treatment processes in the 1980s. According to the experts’ prediction, by the end of this century,
