Tungsten Carbide Spraying and Coating Process
What is the hardness of tungsten carbide thermal spray coatings? Theoretically, tungsten carbide thermal spray coatings can achieve a hardness of 65 to 70 HRC—this represents the theoretical hardness attainable by domestic thermal spraying technologies. When applying tungsten carbide coatings to sealing surfaces, the process also increases the difficulty of subsequent grinding and lapping operations; therefore, it is recommended to use diamond abrasive paste for grinding. If the sealing surface is a hard seal, repeated opening and closing may affect the integrity of the tungsten carbide coating—this should be taken into account. I. Common Coating Types, Their Properties, and Application Ranges Coating Material | CrN (Chromium Nitride) | TiN (Titanium Nitride) | TiCN (Titanium Carbonitride) | TiAlN + WC (Tungsten Carbide) | Carbon Film Hardness (HV) | 1700 | 2200 | 3000 | 3000 | 1700 Friction Coefficient | 0.5 | 0.4 | 0.4 | 0.1 | <0.1 Residual Stress (MPa) | -1.5 | -2.5 | -4.0 | -1.7 | N/A Processing Temperature (°C) | 400 | 450 | 450 | 450 | 450 Oxidation Resistance Temperature (°C) | 700 | 600 | 750 | 850 | 850 Coating Thickness (μm) | 1–6 | 1–4 | 1–4 | 1–4 | 1–4 Coating Color | Silver-white | Golden-yellow | Gray | Dark gray-black | N/A Coating Structure | Single-layer film | Single-layer film | Multi-layer film | Multi-layer film | N/A Features: - Good adhesion, oxidation resistance, and corrosion resistance. - Widest application range. - High hardness, excellent wear resistance, and good toughness. - Combines the properties of TiAlN and WC/C, ensuring superior machining quality. - Suitable for cutting copper-based metals, forming tools, molds, and parts. Offers better wear resistance than traditional chrome plating and effectively prevents sticking and adhesion during plastic injection molding, die casting, and powder sintering processes. - Applicable to turning and milling inserts, drill bits, milling cutters, taps, gear-cutting tools, punches, forming dies, stamping dies, injection and die-casting mold components, wear-resistant parts, mechanical components, and decorative items. - An excellent choice for cutting ferrous metals, plastic molding dies, and wear-resistant workpieces. - Ideal for cutting, forming, and punching tools that require high-speed cutting, high feed rates, and frequently experience impact at the cutting and forming edges. Offers greater wear resistance and higher temperature stability than TiN. However, attention must be paid to the material and surface condition of the substrate being coated. - Suitable for high-speed cutting of high-hardness materials. Tools made from high-speed steel and tungsten steel coated with this film effectively protect cutting edges from wear and ensure smooth chip evacuation, enhancing the efficiency and performance of drilling, tapping, and dry cutting of steels and aluminum alloys. Coating Material | TiC (Titanium Carbide) | Tungsten Carbide (WC) | WC/C (Carbon-Tungsten Composite) | TiAlN (Titanium Aluminum Nitride) | DLC (Diamond-Like Carbon) Hardness (HV) | >3500 + 1000 (microhardness at 50g load) | 3000–3500 | 2500 (microhardness at 50g load) | >0.1 (TiConTiC) | 0.1 | 0.4 | 0.1–0.2 Friction Coefficient | N/A | N/A | N/A | N/A | N/A Residual Stress (MPa) | -1.0 | -1.5 | N/A | N/A | N/A Processing Temperature (°C) | 250 | 450 | N/A | N/A | N/A Oxidation Resistance Temperature (°C) | 300 | 800 | 350 | N/A | N/A Coating Thickness (μm) | 1–4 | 1–5 | N/A | N/A | N/A Coating Color | Gray | Dark gray-black | Dark purple-gray | N/A | N/A Materials—Equipment—Processes—Solutions We have accumulated extensive experience in coating applications and are now successfully replicating these case studies. We will guide you through the entire coating manufacturing transition process, ensuring: - Rapid production start-up; - A reliable supply solution covering materials, equipment, and processes comprehensively; - Coating trials conducted either on-site at your facility or at our technical center; - Consistent coating quality and efficiency.
