Increase the wear resistance of stainless steel through nitriding solutions. The thin film plasma nitriding equipment use vacuum process for modification of surfaces. We specialize in pulse plasma ion nitriding in the United States to rig stiff apps.The micro frames and properties of commercial plasma nitriding are strongly affected by bias volts. At different bias volt and by high freq and low volt, for pure iron commercial nitriding processes the layers show best wear and corrosion resistance.
