| Abstract: |
| High Velocity Air Arc Spray (HVAS) and High Velocity Oxygen/Air Fuel spray (HVO/AF) were successfully developing according to air dynamics and principle of rocket engines, which can spray corrosion-resistance, wear-resistance, electric and electric-insulated coatings with good performance. The two high velocity thermal spray technologies can be used for remanufacturing of mechanical parts with high quality, high efficiency, energy saving, material saving and environmental protection, extending the service life. Wasted parts were reused with good economic benefit. HVAS can spray metal, alloy and composite coatings with high bonding strength and low porosity, which was widely used in long life corrosion resistance and wear resistance. HVO/AF has the functions both of HVOF and HVAF, which can meet the requirements of many materials through adjusting the flame velocity and temperature. HVO/AF is the best technique for spraying of carbide coatings with well mechanical and wear resistant performance, which will be widely used in surface hardening of parts. |
