○○○○○○○○○○○○○○○○○○−○○−○−PUNCH Industry treats the components for pressing die by using the Physical Vapor Deposition （PVD） method which includes TiCN（Titanium carbonitride）,TiN（Titanium nitride）,CrN （Chromium nitride）,DLC（Diamond like carbon）,CMTi（Multi-layer composite film）.Physical Vapor Deposition（PVD）method has the advantage of low temperature treatment which enables base material to be coated without hardness degradation or thermal deformation. There is no need to control sizes with consideration of the thickness of coated layer which has been standardized to the unit of μm.Types and features of coating treatmentThe features and available materials for our coating treatments which based on physical vapor deposition （PVD）method are shown in table 1.Features of Coating TreatmentsFcoating（Composite surface treatment）Color：dark greyColor：dark greyColor：gold72Coating methodTypes of coatingThe material for highーtemperature tempering may not be included in this table.The hardness is for coating layer itself. When use the Vickers Hardness Test（Test load 50g）for measuring thehardness of base material, values in（ ）are the norms. The coating methods which can be used as norms are：TiCN（Titanium carbonitride）,TiN（Titanium nitride）,CrN （Chromium nitride）. The coating treatments （TiC Titanium carbonization, est.） which use the chemical vapor deposition （CVD） method are available either. But the high temperature coating treatment could deform the shape of product. Please enquire us while ordering. For the details, refer to the introduction on the right page. Fcoating is one of the conventional PVD（Physical vapor deposition）methods. Fcoating significantly improved the adhesive of coated film and impact resistance, and enhanced the durability of coating layer. The Fcoating is a new kind of composite surface treatment The base material of the product is strengthened by physical vapor deposition（PVD） method, which raising the adhesive performance of the TiCN film. The Fcoating could bring the excellent operational performance in punching high tensile material and stainless steel.Deatails P.1108TiCN（Titanium carbonitride）The coating layer has the feature of both high hardness of TiC（Titanium carbonization）and toughness of（Titanium nitride）, which they are inversely proportional to each other, so the relationship of hardness and toughness is depend on content ratio of C（Carbon）and N（Nitrogen）. PUNCH Industry can set the proportion of C and N according to specific purposes, and enhance the TiCN coating layer’s performance, which TiC or TiN can not reach. The surface hardness could reach 3000HV which is higher than TiC and also the coating layer has the effectiveness of multi-layer composite film. TiCN has been widely used in the punching operations which require higher hardness and lower friction coefficient, such as cutting tools （For processing the materials such as SUS）, ejector punches, and forming mold. Deatails P.1112Because of the large range of coating temperature, TiN has been widely applied as a kind of typical PVD method. The toughness of TiN is higher than TiC, and the blade sharpness will not be reduced. So, this treatment has been widely applied for cutting tools. Low treating temperature will not lower the hardness of base material and also its shape will not be deformed. This treatment is particularly suitable for the base material which its quenching temperature is higher than treating temperature. Product surface hardness could exceed 2200HV after this treatment which been generally applied for cutting tools, components for automobile driving systems, pressing die, plastic molds and die-casting molds.Thickness of Hardness of layerlayer【HV】2700Allowable temperatureFriction coefficientSKD11Available materialSKH51P/M high-speed steelCemented carbides【μm】【℃】Table 1 The features and available materials of coating treatmentF coatingComposite surface treatmentTiCN Titanium carbonitrideTiNTitanium nitrideCrNChromium nitrideDLCDiamond Like CarbonTitanium multiーstoreyCMTiPhysical Vapor Deposition （PVD） TiN（Titanium nitride）2〜3（1800）400（1800）400（1600）400（1400）70030027002〜324002〜320002〜42〜440002〜325000.60.60.60.50.10.4580Special Coating Treatment
