技術(shù)特點(diǎn)

良好的耐磨性耐疲勞性能(Good wear resistance and fatigue resistance.)

QPQ技術(shù)能極大地提高各種黑色金屬零件表面的硬度和耐磨性,降低摩擦系數(shù)。產(chǎn)品經(jīng)過QPQ處理后,耐磨性比常規(guī)淬火、高頻淬火高20倍以上,比滲碳淬火高14倍以上,比鍍硬鉻和離子化高2倍以上。

疲勞試驗(yàn)表明:該工藝可使中碳鋼的疲勞強(qiáng)度提高40%以上,比離子氮化,氣體氮化效果均好。該工藝特別適合于形狀復(fù)雜的零件,解決技術(shù)關(guān)鍵,讓變形難題迎刃而解。

QPQ technology can greatly improve the surface hardness and wear resistance of various ferrous metal parts, and reduce the friction coefficient. After QPQ treatment, the wear resistance of the product is 20 times higher than that of conventional quenching and high frequency quenching, 14 times higher than that of carburizing quenching, and 2 times higher than that of hard chromium plating and ionization.

The fatigue test shows that the process can increase the fatigue strength of medium carbon steel by more than 40%, which is better than ion nitriding and gas nitriding. This technology is especially suitable for the parts with complex shape. It solves the key technology and solves the deformation problem.

良好的抗腐蝕性能（Good corrosion resistance）

對45鋼在不同工藝處理的樣品按ASTMBI17標(biāo)準(zhǔn)進(jìn)行了連續(xù)噴霧試驗(yàn),結(jié)果表明:經(jīng)過QPQ處理的樣品抗腐蝕性是發(fā)黑處理的16倍,是鍍鋅處理的6倍以上,是鍍鉻處理的3倍以上,是鍍鎳鉻處理的2倍。

Continuous spraying tests were carried out on 45 steel in different processing samples according to ASTMBI17 standard. The results showed that the corrosion resistance of samples treated by QPQ was 16 times that of blackening, 6 times higher than that of zinc plating, 3 times more than that of chrome plating, and 2 times that of nickel chromium plating.

產(chǎn)品處理以后變形小（The product is less deformed after processing）

工件經(jīng)QPQ處理處理之后幾乎沒有變形產(chǎn)生,可有效的解決常規(guī)熱處理方法難以解決的硬化變形難題。目前,QPQ技術(shù)在眾多得軸類零件、細(xì)長桿件上應(yīng)用得非常成功,有效的解決了一直以來存在的熱處理硬化和產(chǎn)品變形的矛盾。

After QPQ treatment, there is almost no deformation, which can effectively solve the problem of hardening deformation which is difficult to be solved by conventional heat treatment. At present, QPQ technology has been successfully applied to many shaft parts and slender members, effectively solving the contradiction between heat treatment hardening and product deformation.

可以代替多道熱處理工序和防腐蝕處理工序,時(shí)間周期短（It can replace the multi-heat treatment process andanti-corrosion treatment process with a short time cycle）

工件經(jīng)QPQ處理后,在提高其硬度和耐磨性的基礎(chǔ)上同時(shí)提高其抗腐蝕能力,并且形成黑色、漂亮的外觀,可以代替常規(guī)的淬火一回火一發(fā)黑(鍍鉻)等多道工序,縮短生產(chǎn)周期,降低生產(chǎn)成本。大量的生產(chǎn)數(shù)據(jù)表明,QPQ處理與滲碳淬火相比可以節(jié)能50%,比鍍硬鉻節(jié)約成本30%,性價(jià)比高。

After QPQ treatment, on the basis of improving the hardness and wear resistance of the workpiece, the corrosion resistance of the workpiece is improved at the same time, and a black and beautiful appearance is formed, which can replace the conventional quenching tempering blackening (chrome plating) and other processes, shorten the production cycle and reduce the production cost. A large number of production data show that QPQ treatment can save 50% energy compared with carburizing and quenching, 30% cost compared with hard chromium plating, and has high cost performance ratio.

QPQ技術(shù)適用材料的范圍廣泛（QPQ technology applies to a wide range of materials）

QPQ技術(shù)適用于碳鋼、合金結(jié)構(gòu)鋼、各類不銹鋼、工模具鋼、鑄鐵及鐵基粉末冶金等材料。該技術(shù)可代替多種熱處理工藝和防腐蝕工藝,如表面淬火、薄層滲碳、氣體氮化、離子氮化、鍍鉻、鍍鎳、鍍鋅、發(fā)黑等工藝。

QPQ technology is suitable for carbon steel, alloy structural steel, all kinds of stainless steel, die steel, cast iron, iron-based powder metallurgy and other materials. This technology can replace many kinds of heat treatment and anti-corrosion processes, such as surface quenching, thin layer carburizing, gas nitriding, ion nitriding, chromium plating, nickel plating, zinc plating, blackening and so on.
