QPQ carbonitriding, QPQ nitriding, QPQ carburizing, QPQ heat treatment

"QPQ" is the English "Quench-P0lish-Quench" acronym. Intended for a polishing a quench hardening. It was made after the salt bath process, in order to reduce the roughness of the surface can be polished to a surface of the workpiece, and then make a oxidation in a salt bath, this high precision parts and surface roughness of the workpiece It is very necessary. In domestic call it QPQ salt bath processing technology. QPQ salt bath processing technology, can greatly improve the wear resistance, corrosion resistance of the metal surface, and almost no deformation of the workpiece is a new metal surface modification technology to strengthen. This technology enables nitriding process and the oxidation process of the composite; composite nitride and oxide; wear resistance and corrosion resistance of the composite; composite heat treatment technology and preservative technology. QPQ salt bath processing technology in the 1970s, invented by the German company, after decades of continuous development of improved, more and more wide range of applications, in a foreign country is considered to be significant progress metal surface hardening technology in the field, the It is called a new metallurgical processes. Currently, QPQ salt bath processing technology in China has also been widely promoted, particularly in the automobile, motorcycle, shaft products, electronic components, textile machinery, machine tools, electrical switches, use the tool and die very prominent effect. Tengzhou is a professional metal surface heat treatment, metal surface hardening treatment of high-tech enterprises, always walk in the cutting edge of technology liquid salt bath nitriding. The company through the use of advanced German salt bath nitriding, hard nitriding, QPQ, SQP, NQPQ, OPO, strengthening black, stainless steel black, abrasion treatment processing technology, QPQ equipment, QPQ finished salt sales, QPQ complete technology transfer etc ...... can strengthen the metal surface to improve the surface hardness, effective solution to the metal parts corrosion, abrasion, fatigue, deformation and other issues. Widely used in auto parts, engineering machinery, mold manufacturing and a variety of wear-resistant parts, corrosion and other pieces Process easily deformable parts and other industries.
