Schematic of HVOF High-Velocity Oxy-Fuel Coating
Characteristics
-
01
Fuel (propane, kerosene, etc.) is combusted under high pressure in a specially designed chamber.
-
02
Powder-form coating materials are transferred into the flame through a delivery system and melted by thermal energy of about 3000℃.
-
03
The molten material is sprayed onto the substrate at high speeds of 700m/sec to form the coating film.
-
04
Coating is possible while maintaining the substrate surface at a low temperature without thermal deformation of the substrate.
-
05
A coating method allows carbides such as WC, Cr3C2, nickel, nickel alloys, and non-metals to have high density and adhesion.
