Estimating the term…
The invention discloses an AlCrVTiSiON nano-gradient coating with surface pre-oxidation and a preparation method thereof, belonging to the technical field of coatings. The AlCrVTiSiON nano gradient coating is prepared by arc ion plating technology, wherein the target materials are selected from metal Cr target, V target, AlCrSi target and AlTiSi target. In order to further improve the heat resistance of the coating and increase the cutting amount during service, the AlCrVTiSiON nano-gradient coating with O element content increasing from inside to outside was formed. The prepared coating has good heat resistance, which is suitable for high-speed cutting and improves processing efficiency.
A pre-oxidized AlCrVTiSiON nano-gradient coating, wherein the nano-gradient coating is deposited on a metal or silicon substrate, and the content of oxygen gradually increases from the inside to the outside, and wherein the coating surface is a protective layer of AlCrVTiSiON oxide.
