2353 Quasi-One-Dimensional Analysis of High Velocity Oxy-Fuel Thermal Spray Gun : Effect of Nozzle Shape on Particle Behavior
Details
The gas velocity in the High-Velocity Oxy-Fuel (HVOF) process is highest in many types of thermal spraying process. Previous works show that the higher velocity of the coating particle seems to give high-quality coating. This paper analyzes the behavior of coating particle as well as the gas flow of inside the HVOF thermal spraying gun by using quasi-one-dimensional analysis. The effect of the nozzle shape on the particle velocity and temperature is examined.
