还在为工件表面处理的问题发愁吗？看看这里。

 

QPQ是什么？ What is QPQ？

 

“QPQ”是英文“Quench—Polish-Quench”的缩写。原意为淬火一抛光一淬火。QPQ技术是冶金学领域内带有革命的新技术，它是在两种不同性质的盐浴中使金属表面渗入多种元素，同时使其耐磨性和抗蚀性比常规热处理和表面防腐技术成倍的提高。

 

QPQ is“Quench-Polish-Quench”for short in English. QPQ technology is a new revolution technology in the field of metallurgy. It seeps a variety of metal elements to the surface in the two different nature of the bath. By QPQ treatment, the wear resistance and anti-corrosion resistance of workpiece are exponentially increased than conventional heat treatment.

 

经QPQ处理后有什么不一样? What is the Distinguishing Feature of QPQ?

 

1. 极高的耐磨性、良好的耐疲劳性 Extremely high wear resistance and good fatigue resistance

 

根据滑动磨损实验的结果，QPQ处理后，中碳钢的耐磨性可达到常规淬火的30倍，低碳钢的耐磨性是渗碳淬火处理的14倍，是离子氮化处理的2.8倍，是镀硬铬处理的2.1倍。QPQ处理后中碳钢的疲劳度可以提高40%以上（图1）。滚动磨损实验的结果大体相似。

 

According to the result of slid-wear testing, the wear resistance of medium carbon steel with QPQ treatment is 30 times than conventional quenching. The wear resistance of low carbon steel with QPQ treatment is 14 times than cemented quenching, is 2.8 times than ion nitriding, and is 2.1 times than plating hard chromium. Resistance to fatigue of medium carbon steel can be increased by more than 40%（pic.1）. The results of rolling wear experiment is generally similar to slid-wear testing.

 

2. 极好的抗蚀性 Excellent corrosion resistance

 

中碳钢经QPQ处理后，在盐雾中的抗蚀性为镀硬铬的70倍，镀装饰铬的35倍，比1Crl8Ni9Ti不锈钢还高5倍。工件大气存放实验和硫酸铜浸蚀实验都表明，经QPQ技术处理后钢件具有极高的抗蚀性（图2）。

 

The corrosion resistance of carbon steel, by QPQ treatment, is 70 times than hard chromium plating in salt fog，is 35 times than decorative chromium plating, and is 5 times than that of 1Cr18Ni9Ti stainless steel. Both workpiece atmosphere storage experiment and copper sulfate erosion experiment show that steel parts are of high corrosion resistance by QPQ treatment(Pic.2).

 

 

3. 极小的变形 Minimal Deformation

 

QPQ处理后工件几乎不变形，是变形最小的硬化技术。可以解决常规硬化方法无法解决的硬化变形难题。可以替代淬火（高频淬火，渗碳淬火）——回火——发黑（镀铬）等多道热处理和防腐工序。采用QPQ技术可大大缩短生产周期，降低生产成本。

 

QPQ is minimal deformation hardening technology, which makes no deformation for the work pieces . It is used to solve the deformation problem which cannot be solved by conventional methods . As well as it can replace quenching (high-frequency quenching, carburizing quenching) - tempered - black (chrome plated) processings. QPQ technology can greatly shorten the production time and reduce the cost of production.

 

4. 无公害化水平高，不污染环境 Non-environmental Pollution

 

经有关环保部门监测鉴定，各种有害物质排放量均远低于国家排放标准允许值。

 

Identified by environmental protection departments, all kinds of harmful substances emissions are lower than the national standard.

 

第二代QPQ技术 The Second Generation QPQ Technology

 

我公司的第二代QPQ技术使碳钢化合物层厚度可达到30μm以上，达到了国内领先水平。利用电流催渗加快渗层的形成速度等方法，研究开发出的第三代QPQ技术（即超深层QPQ技术）可使碳钢化合物层厚度达到60μm以上。本技术是拥有完全自主知识产权的独创新技术，达到国际先进水平。

 

The second generation QPQ technology of CTRI enable carbon compound layer thickness reach to more than 30μm, which is the leading level in China. The third generation of QPQ technology(namely ultra deep layer QPQ Technology), makes the thickness of carbon steel compound layer reach to 60 μm or even more by accelerating the formation of permeation layer. It is a unique technology with full independent intellectual property rights in the international advanced level.
