| 摘要 |
The invention provides a method of treating an artifact to combat unauthorized tampering with the identity thereof. The method comprises forming a coating on at least part of a surface of the artifact, to provide the artifact with an identification mark which comprises said coating. Forming the coating is by means of thermal spray-coating. The method can be used to coat a pre-formed identification mark on the surface, or to apply an identification mark to the surface, the mark being an engine number, chassis number, or the like. The method acts to render vehicle or aircraft theft, and forgery of parts thereof, more difficult.
