China WC-17Ni HVOF/HVAF Thermal Spray Powder Suppliers | High-Performance Factory Solutions for Wet Environments
Basic parameters
The chemical composition of DG.WC-Ni17 powder mainly includes nickel (Ni17), carbon (C4.8) and tungsten (W), and the remaining components are the remainder of tungsten. The powder is produced by agglomeration and sintering process, and the formed particles present a good spherical shape and have 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 HV950 to 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-Ni17 is between 40-50%, which means that it can effectively reduce material waste and improve production efficiency during the spraying process.
Product Performance
The coating of DG.WC-Ni17 powder has many excellent properties. First, its high hardness and dense coating structure make it perform well in the face of particle wear and sliding wear, which can effectively extend the service life of the equipment. Compared with traditional WC-Co spray powder, DG.WC-Ni17 is more superior in corrosion resistance and is particularly suitable for the chemical industry and marine environment.
The maximum working environment temperature of the coating can reach 500℃, and it has non-magnetic characteristics, which makes it more widely used in high temperature 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 feature makes DG.WC-Ni17 an ideal choice for key components such as offshore oil exploration equipment, offshore heavy industry, and various ball valves and valves.
Application Areas
DG.WC-Ni17 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 preferred material for many equipment. In marine engineering, equipment often faces harsh environmental conditions. The high temperature tolerance and non-magnetic characteristics of DG.WC-Ni17 make it widely used in offshore oil exploration and heavy industry. In addition, with the development of industrial automation and intelligence, DG.WC-Ni17 has gradually been used in various high-end mechanical equipment and precision instruments.
Spraying process parameters
In the spraying process, it is very important to choose the right spray gun and process parameters. Taking the Lijia kerosene supersonic spray gun as an example, the powder particle size is 15-45um, the barrel size is 4 inches, the kerosene consumption is 23L/h, the oxygen flow is 900L/min, the carrier gas flow is 8.5L/min, the powder feeding 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 according to different equipment to achieve the best spraying effect.
Summarize
DG.WC-Ni17 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-Ni17 will bring higher value and benefits to more industries. Whether in the fields of chemical industry, marine engineering or high-end machinery manufacturing, DG.WC-Ni17 will play its unique advantages and promote the development and progress of the industry.
