Heat treating technology development closely connected with three large scale technology andequipment importing is reviewed, and the fbatures of hcat treating specialization and large scale production areanalyzed. Main tcchnical progresses ofgas carbonitriding instead ofliquid cyaniding, improvement ofcontrol accuracyin gear carburizing, improvement of carburizing layer unitbrmity by preoxidation, increment of raw gas purity incontrolled atmosphere use of fbrging wastc heat cooling control for normalizing,...

回顾我国汽车工业热处理技术发展与3次大规模技术引进密切相关，分析了汽车工业热处理技术发展专业化，规模生产的特点，列举了10年来在气体碳氮共渗取代液体氰化；齿轮渗碳控制精度提高；采用预氧化工艺提高渗碳层均匀性；解决可控气氛中原料气纯度以及锻造余热控冷正火和等温正火技术的应用等方面嵢〉玫闹饕删停岢龈咝＝⑷却砩璞缸ㄒ档冉ㄒ椤

This can be done carburizing, cyaniding, nitriding, carbonitriding, induction hardening, and flame hardening.

这可以通过渗碳剂、氰化、渗氮、碳氮共渗、感应淬火、火焰淬火来完成。

Cyaniding Cyaniding, or liquid carbonitriding as it is sometimes called, is also a process that combines the absorption of carbon and nitrogen to obtain surface hardness in low-carbon steels that do not respond to ordinary heat treatment.

氰化 氰化，有时称为液体碳氮共渗，也是一种结合了吸收碳和氮来获得表面硬度的工艺，它主要用于不适合通常热处理的低碳钢。

Carbonitriding Carbonitriding, sometimes known as dry cyaniding or nicarbing, is a case-hardening process in which the steel is held at a temperature above the critical range in a gaseous atmosphere from which it absorbs carbon and nitrogen.

碳氮共渗碳氮共渗，有时也称为干法氰化或渗碳氮化，是一种表面硬化工艺。通过把钢放在高于临界温度的气体中，让它吸收碳和氮。

Earbonitriding Earbonitriding, sometimes known as dry cyaniding or nicarbing, is a case-hardening process in which the steel is held at a temperature above the critical range in a gaseous atmosphere from which it absorbs carbon and nitrogen.

Carbonitriding, sometimes known as dry cyaniding or nicarbing, is a case-hardening process in which the steel is held at a temperture above the critical range in a gaseous atmosphere from which it absorbs carbon and nitrogen.

碳氮共渗碳氮共渗，有时称为干氰化或nicarbing ，就是一个例子硬化过程中，钢铁是在温度高于临界各种气体的气氛它吸收碳和氮。

One, use rangeNitrogen of the shallow-layer cementite that is used at bearing, chain, bearing pin, fastener, small-sized mechanical spare parts, carbon in all ooze, brightness quenchs.

一、应用范围用于轴承、链条、销轴、紧固件、小型机械零件的浅层渗碳、碳氮共渗、光亮淬火。

Meanwhile, it also presents that the Heat treatment cementation using purified natural gas, Methyl alcohol; methanol can not only improve the quality of products, but also enhance the carburizing speed, reduce the gas consumption and extend the lifespan of equipment spare parts and so on.

同时，提出了热处理渗碳采用净化后的天然气、氨水、甲醇不但可提高产品质量，而且还具有提高渗碳和碳氮共渗速度、降低气源消耗和延长设备备件使用寿命等功效。
