WR SVCC SYSTEM is a thermal spraying process that produces high density coatings of less than 1% porosity. The Results are very close to HVOF Process ar even better.The oxide levels is also less than 4%.
In this process, the high electric arc energy from the two consumable wires heats gas inside a small vessel which is pressurized due to both ionization and the hot expanding gas, a jet stream exits a small port in front of which the wires are positioned and then melted, atomized, and propelled to the substrate. Controlling the arc gap is another essential part of the process. WR SVCC SYSTEM has mastered means to maintain an exact arc gap to allow nano scale particles to develop during atomization. Without this arc gap control the wires will actually interfere with the atomization process and cause a mix of large and small particles and therefore increase porosity.
