VANADIS 6Surface treatmentSome cold work tool steels are given a surfacetreatment in order to reduce friction and increasewear resistance. The most commonly used treatmentsare nitriding and surface coating with wearresistant layers produced via PVD or CVD.The high hardness and toughness together with agood dimensional stability makes VANADIS 6ideal as a substrate steel for various surface coatings.NITRIDING AND NITROCARBURIZINGNitriding and nitrocarburizing result in a hardsurface layer which is very resistant to wear andgalling.The surface hardness after nitriding is approximately1250 HV 0,2 kg . The thickness of the layershould be chosen carefully, considering the highalloying elements, to suit the application in question.PVDPhysical vapour deposition, PVD, is a method ofapplying a wear-resistant coating at temperaturesbetween 200–500°C (390–930°F).CVDChemical vapour deposition, CVD, is used for applyingwear-resistant surface coatings at a temperatureof around 1000°C (1830°F). It is recommendedthat the tools should be separately hardenedand tempered in a vacuum furnace after surfacetreatment.Blanked parts. Punch in VANADIS 6,die in VANADIS 10.8
