QPQ 技术是表面强化技术领域内具有革命

性的新技术，它是将金属工件放入两种不同性

质的盐浴中，在金属表面渗入多种元素，同时

使工件耐磨性能和抗腐蚀性能成倍增加，此外

该技术还具有工件微变形、无公害等优点。

成都工具研究所有限公司表面技术部历经长

期试验，于上世纪 80 年代末期成功研发出成分

独特的盐浴配方，一举打破国外公司对 QPQ 技

术的独家垄断。该配方不仅更具环保性，技术水

平达到国际领先，还大幅降低了生产成本，相比

国外同类技术拥有明显的成本优势。凭借优越的

性能、稳定的质量与适中的价格，该技术深受广

大用户青睐，并先后斩获联合国发明创新奖、国

家科技进步二等奖、四川省科技进步一等奖等多

项殊荣，同时被认定为国家级新产品，入选“九五”

期间国家级重点推广科技项目。

QPQ technology is a revolutionary new technology in the field of

surface strengthening technology. It puts the metal workpiece into two

kinds of salt bath with different properties, and penetrates multiple

elements on the metal surface, at the same time, the wear-resistant

property and corrosion resistance of the workpiece are doubled. In

addition, the technology has the advantages of micro-deformation of

the workpiece, no public hazard, etc.

The Surface Technology Department of Chengdu Tool Research Institute

Co., Ltd. successfully developed the salt bath formula with unique

ingredients in the late 1980s after long-term tests, breaking the exclusive

monopoly of foreign companies on QPQ technology at one stroke.

The formula is not only more environmentally friendly, the technical

level reaches the international leading level, but also greatly reduces

the production cost, and has obvious cost advantages compared with

similar technologies abroad. With superior performance, stable quality

and moderate price, this technology is favored by users, and has

successively won the United Nations Invention and Innovation Award,

honors. Meanwhile, it is recognized as a national new product and

selected as a national key promotion science and technology project

during the \"Ninth Five-Year Plan\" period.

The QPQ treatment technology of Chengdu Tool Research Institute

Co., Ltd. can be subdivided into low-temperature QPQ technology,

conventional QPQ technology and deep QPQ technology according to

different operating temperatures. The three processes have different

focuses on application scenarios, permeability layer performance and

product characteristics, which can meet different demands.

Since the first technology transfer user realized mass production,

the cumulative service of this technology has been more than 30

years. At present, a number of QPQ technology production lines

have been built in China, covering more than 20 provinces, cities

and autonomous regions, widely used in automobiles, motorcycles,

locomotives, textile machinery, engineering machinery, petroleum

Technology

The batch application nitriding temperature

range of low-temperature QPQ technology is

(400 ℃ - 480 ℃ ). For carbon steel or alloy

steel materials with low tempering or

tempering temperature, the conventional

QPQ technology treatment will reduce the

core hardness and cannot meet the overall

performance of the parts, such as tensile

strength; For stainless steel materials, the

conventional QPQ technology treatment

will cause the corrosion resistance of the

product to decline; Low-temperature QPQ

technology is used to effectively ensure

the mechanical properties of the product.

At present, this technology is widely

used in military industry, Third Harbor

Engineering Co., Ltd. and mold industry.

Due to the shallow permeability layer

of conventional QPQ technology, the

application scope is greatly limited. In

order to solve this problem, the deep

QPQ technology has been successfully

developed after more than 10 years

of intensive test research. The batch

application of deep QPQ technology has

the nitriding temperature range of (590

℃ - 650 ℃ ), and the thickness of the

compound has increased from 15~20

microns of the original QPQ technology to

over 30~40 microns.

Figure 3 shows the difference between the metallographic

and deep QPQ technology. The test results show that the

thickness of compound layer is doubled after the deep QPQ

treatment, and all kinds of properties of the workpiece are

greatly improved.

Wear-resistance: the sliding wear resistance of 45 steel after deep QPQ treatment is 4 times of that of common QPQ

treatment, and the rolling wear test of workpiece has similar results.

Corrosion resistance: the weight loss test corrosion resistance of 45 steel after deep QPQ treatment is 12 times of that

of common QPQ treatment. In the salt spray test, the corrosion resistance is more than 1 time of that of common QP

Q treatment. If the deep QPQ technology is combined with the sealant, the salt spray test corrosion resistance can

reach more than 300h or even higher.

Impact toughness: impact toughness of 45 steel after deep QPQ treatment is 1.98 times of that of common QPQ
