TENIFER/QPQ HEF PATENT Nitro-carburation treatments associate thermochemical diffusion in salt baths with a passivation and a finish treatment. It makes possible to combine corrosion, wear and fatigue resistance properties on steel and cast iron. This treatment is combined with mechanic cleaning operations/polishing as par t of QPQ in order to lower the sur face roughness. Treatment parameters: TENIFER treatment temperature is set between 500 and 630°C and treatment time varies between 30 and 210 minutes. Remarks: The installed equipment allows the treatment of parts until a diameter of 1300 mm and a height of 2300 mm. Precautions to be taken: Schedule 3-hour thermal stress relieving at a 20°C higher temperature than the treatment temperature before final machining. Applications examples: • Gears • Camshafts • Slides • Bearings • Turbine liners • Tumbler • Racks • Cutting tool • Crankshaft • Hydraulic cylinder • Rockets • Wheel hub •Connecting rods, cardan • Articulation pins • Molds for aluminum alloys flows • Pistons…
