QPQ

QPQ processing technology, which is the abbreviation of Quen ch -Polish-Quench. It refers to placing black metal parts in two salt baths with different properties, and forming a composite layer through the infiltration of multiple elements into the metal surface, thereby achieving the goal of surface modification of the parts. It has not undergone quenching, but has achieved the effect of surface quenching, so it is called QPQ at home and abroad. QPQ treatment is a composite treatment technology that combines heat treatment and
anti-corrosion treatment in one go. The treatment temperatue is low, the time is short, and it can simultaneously improve the surface
hardness, wear resistance, and corrosion resistance of parts, reduce friction coefficient, reduce deformation, and be pollution-free. It has
the advantages of optimizing processing procedures, shortening production cycles, and reducing production costs, and has been
recognized and praised by many manufacturers. Famous multinational companies such as GE in the United States, GM, Volkswagen in Germany, Mercedes Benz, Toyota in Japan, and Honda have all adopted it extensively. This technology is considered by the heat treatment industry at home and abroad as a great progress in the field of metal surface strengthening technology, and is called a revolutionary new technology in the field of metallurgy.
