China Suppliers Factory WC-12Ni HVOF/HVAF Thermal Spray Powder for Wet Environments and Superior Durability
Basic parameters
The chemical composition of DG.WC-Ni12 powder mainly includes nickel (Ni12), carbon (C5.3) and tungsten (W), and the remaining components are the balance of tungsten. The powder is produced using agglomeration sintering technology, and the particles formed have a good spherical shape and excellent fluidity. This fluidity enables the powder to be evenly distributed during the spraying process, ensuring the density and uniformity of the coating.
The hardness of the coating ranges from HV1000-1200, showing its excellent wear resistance. The bonding strength exceeds 70Mpa, ensuring good adhesion between the coating and the substrate. In addition, the deposition efficiency of DG.WC-Ni12 is between 40-50%, which means that the waste of materials can be effectively reduced and production efficiency improved during the spraying process.
Product performance
The coating of DG.WC-Ni12 powder has a variety of excellent properties. First of all, its high hardness and dense coating structure make it perform well in the face of grain wear and sliding wear, effectively extending the service life of the equipment. Compared with traditional WC-Co spray powder, DG.WC-Ni12 has superior corrosion resistance and is especially suitable for the chemical industry and marine environment.
The maximum working environment temperature of the coating can reach 500°C, and it has non-magnetic characteristics, which makes it more widely used in high temperatures and special environments. The corrosion resistance of the coating is more outstanding than that of WC-10Ni powder, and the increase in nickel content further improves its corrosion resistance. This characteristic makes DG.WC-Ni12 an ideal choice for key components such as offshore oil exploration equipment, offshore heavy industry, and various types of ball valves and valves.
Application Areas
DG.WC-Ni12 powder has a wide range of applications, especially in the chemical industry. Due to its excellent wear resistance and corrosion resistance, it has become the first choice material for many equipment. In marine engineering, equipment often faces harsh environmental conditions. The high temperature tolerance and non-magnetic characteristics of DG.WC-Ni12 make it widely used in offshore oil exploration and heavy industry. In addition, with the development of industrial automation and intelligence, DG.WC-Ni12 has gradually been used in various high-end mechanical equipment and precision instruments.
Spraying process parameters
During the spraying process, it is crucial to select the appropriate spray gun and process parameters. Taking the Lijia kerosene type supersonic spray gun as an example, the powder particle size is selected from 15-45um, the barrel size is 4 inches, the kerosene consumption is 24L/h, the oxygen flow is 900L/min, and the carrier gas flow is 8.5L/min. The powder speed is between 80-100g/min, and the spraying distance is 340-380mm. These parameters are for reference only. In actual operation, they need to be adjusted accordingly according to different equipment to achieve the best spraying effect.
In short, DG.WC-Ni12 thermal spray powder is becoming an important material in the field of surface treatment due to its excellent performance and wide application prospects. With the continuous advancement of technology and the continuous expansion of application fields, DG.WC-Ni12 will bring higher value and benefits to more industries.
