METHOD OF PREVENTING OXIDATION OF METALS IN THERMAL SPRAYING |
| 摘要 |
The invention relates to a method for preventing the oxidation of metals in thermal spraying by coating the metallic powders to be used with nanocarbides, to a coating achieved using the method as well as to a method for treating the metal powder with nanocarbides. The methods according to the invention are suitable for all metal powders used in thermal spraying and, as the invention enables the use of cheaper materials, they are economically extremely advantageous. |

1. A method for preventing the oxidation of metals in thermal spraying, comprising
attaching nanocarbides to the surface of metallic powder particles to be used in thermal spraying, followed by spraying the coated metallic powder by thermal spraying into a metal coating on the surface of a body, whereby the nanocarbides provide a reduction reaction of the carbides on the surface of the metal powder particles during the molten state of the spraying, so that the surface of the molten metal drop is not allowed to oxidize. |
