Technology  introduction

    QPQ處理技術，它是Quench-Polish-Quench的縮寫形式。是指將黑色金屬零件放入兩種性質不同的鹽浴中，通過多種元素滲入金屬表面形成複合滲層，從而達到使零件表面改性的目的。它沒有經過淬火，但達到了表面淬火的效果，因此國內外稱之爲QPQ。QPQ處理是一種複合處理技術， 將熱處理與防腐蝕處理一次完成，處理溫度低，時間短，能同時提高零件表面硬度、耐磨性和抗蝕性，減少摩擦系數，變形小，無公害。具有優化加工工序，縮短生産周期，降低生産成本的優點，得到衆多廠家的認可和贊譽，像美國GE、GM公司、德國大衆、奔馳、日本豐田、本田等一些******的跨國公司，均大量采用。此技術被國內外熱處理行業認爲是金屬表面強化技術領域內的巨大進展，把它稱之爲一種冶金學領域內革命性新技術。

    QPQ treatment technology, which is the short form of Quench-polish -Polish-Quench. It means to put theblack metal parts into two kinds of salt bath with different properties, through various elements infiltration intothe metal surface to form composite infiltration layer, so as to achieve the purpose of surface modification ofthe parts. It has not been hardened, but the effect of surface quenching, so it is called QPQ at home andabroad. QPQ treatment is a kind of compound treatment technology. Heat treatment and anti-corrosiontreatment are completed at one time with low temperature and short time. It can improve the surfacehardness, wear resistance and corrosion resistance of the part at the same time, and reduce frictioncoefficient. It has the advantages of optimizing processing procedures, shortening production cycle andreducing production cost, which has been recognized and praised by many manufacturers, such as AmericanGE, GM, Volkswagen of Germany, mercedes-benz, Toyota of Japan, Honda and other famous multinationalcompanies, which have been largely adopted. This technology is regarded a great progress in the field ofmetal surface strengthening technology by the heat treatment industry at home and abroad. It is called as arevolutionary new technology in the field of metallurgy.
