工件大气存放实验和硫酸铜浸蚀实验都表明,经QPQ技术处理后钢件具有极高的抗蚀性(图2)。 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 ste...
16小时前 表面QPQ处理(QuenchPost-QuenchingHeatTreatment)技术,作为一种重要的金属材料热处理方法,在现代工业制造领域中有着广泛的应用。 首先,从应用范围来看,表面QPQ处理的涉及的行业十分多样,包括但不限于机械制造、电子科技以及医疗健康等。在机械制造行业中,许多需要承受重载或恶劣环境的零...
A further improvement of the corrosion resistance can be obtained by a following intermediate's treatment (foremen) (QP), or by an intermediate's treatment (foremen) with a repeated treatment in the AB1 bath (QPQ). QPQ means Quench polish Quench and contains thus the TENIFER-Behandlung in ...
