QPQ 技術(shù)是表面強化技術(shù)領(lǐng)域內(nèi)具有革命
性的新技術(shù)，它是將金屬工件放入兩種不同性
質(zhì)的鹽浴中，在金屬表面滲入多種元素，同時
使工件耐磨性能和抗腐蝕性能成倍增加，此外
該技術(shù)還具有工件微變形、無公害等優(yōu)點。
成都工具研究所有限公司表面技術(shù)部歷經(jīng)長
期試驗，于上世紀(jì) 80 年代末期成功研發(fā)出成分
獨特的鹽浴配方，一舉打破國外公司對 QPQ 技
術(shù)的獨家壟斷。該配方不僅更具環(huán)保性，技術(shù)水
平達(dá)到國際領(lǐng)先，還大幅降低了生產(chǎn)成本，相比
國外同類技術(shù)擁有明顯的成本優(yōu)勢。憑借優(yōu)越的
性能、穩(wěn)定的質(zhì)量與適中的價格，該技術(shù)深受廣
大用戶青睞，并先后斬獲聯(lián)合國發(fā)明創(chuàng)新獎、國

項殊榮，同時被認(rèn)定為國家級新產(chǎn)品，入選“九五”
期間國家級重點推廣科技項目。
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,

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
machiner y, chemical machiner y, firearms, machine tools,

The batch application nitriding temperature
range of conventional QPQ technology is
(500-580 ℃ ). Carbon steel and alloy steel
can obtain 10-20 μm compound layer
and 0.1-0.3mm diffusion layer after
conventional QPQ treatment, and the
surface hardness, wear resistance and
corrosion resistance can be significantly
improved. The diffusion layer of 5-100 μ

treatment of stainless steel materials,
and the surface hardness can reach over

widely used in automobile, engineering
machinery, petroleum machinery and
other industries.

Deep QPQ
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
photos of 45 steel treated by ordinary QPQ technology
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
treatment.

根據(jù)滑動磨損實驗的結(jié)果，QPQ 處理后，中碳鋼的
耐磨性可達(dá)到常規(guī)淬火的 30 倍，低碳鋼滲碳淬火的 14
倍，離子氮化的 2.8 倍，鍍硬鉻的 2.1 倍。滾動磨損實驗
的結(jié)果大體相似。QPQ 處理后中碳鋼的疲勞強度可以提
高 40% 以上。（見圖 1）
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 chromium plating.
Resistance to fatigue of medium carbon steel can be increased by
more than 40% (Figure.1). The result of rolling wear experiment is
generally similar to slid-wear testing.
中碳鋼經(jīng) QPQ 處理后，在鹽霧中的抗蝕性為鍍硬鉻
的 70 倍，鍍裝飾鉻的 35 倍，比 1Crl8Ni9Ti 不銹鋼還高 5 倍。
工件大氣存放實驗和硫酸銅浸蝕實驗都表明，經(jīng) QPQ 技
術(shù)處理后鋼件具有極高的抗蝕性。（見圖 2）
極高的耐磨性、良好的耐疲勞性

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 work-piece atmosphere storage
experiment and copper sulfate erosion experiment show that
steel parts are of high corrosion resistance by QPQ treatment
(Figure.2).
