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.
