Abstract:
1. A method of depositing oxidation-resistant nano thin film on heat-dissipation unit, comprising the following steps: providing a heat-dissipation unit; forming at least one nano thickness coating on a surface of the heat-dissipation unit under vacuum; wherein the at least one nano thickness coating has a thickness of 1 nm to 100 nm, supplying a reduction gas into a high-temperature environment having a temperature ranging between 600° C. and 1000° C. to perform a heat treatment and a reduction process and thereafter a diffusion reaction and a reduction-oxidation reaction occurs between the reduction gas and the heat-dissipation unit and the nano thickness coating on the surface of the heat-dissipation unit wherein the reduction as is selected from the group consisting of H forming a nano thickness thin film of a metal compound selected from the group consisting of nitride, carbide, sulfide and oxide on the heat-dissipation unit by completing the heat treatment, the reduction process, the diffusion reaction, and the reduction-oxidation reaction.
