We, the well acknowledged salt bath nitriding and oxidizing process services provider, Friction Technologies bring you a variety of such services at affordable prices. Our salt bath nitriding & oxidizing process services are popular all around the world, as we always endeavor to cater to each requirement of customers by offering them all best possible services. The QPQ complex slat bath treatment, which mainly consists of nitriding and oxidizing processes, is a surface strengthening technology.

The process is extensively used in many sectors such as manufacturing, engineering and in the mechanical and automobile industry to increase surface wear resistance, to enhance fatigue strength and to improve the corrosion resistance of the treated components. After QPQ treatment, plain-carbon steel can be used instead of stainless steel, whilst the QPQ process can also substitute for anti-corrosion and anti oxidizing processes like blacking, phosphorescing chromium plating, etc.

The oxide layer generated by some techniques consists of magnetite and hematite. The magnetite film can improve the corrosion resistance greatly, but the hematite would decrease the corrosion resistance. However, in our test, the oxide layer of the QPQ treated specimens only made up of magnetite and the corrosion resistance is greatly improved. Relatively, little work has been done concerning the systematic investigations on the techniques of the oxidation process.
