良好的耐磨性耐疲劳性能(Good wear resistance and fatigue resistance.)
QPQ技术能极大地提高各种黑色金属零件表面的硬度和耐磨性,降低摩擦系数。产品经过QPQ处理后,耐磨性比常规淬火、高频淬火高20倍以上,比渗碳淬火高14倍以上,比镀硬铬和离子化高2倍以上。
疲劳试验表明:该工艺可使中碳钢的疲劳强度提高40%以上,比离子氮化,气体氮化效果均好。该工艺特别适合于形状复杂的零件,解决技术关键,让变形难题迎刃而解。
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.
