Embodiment 1

[0036] In this embodiment, the substrate material is 304 stainless steel, and the surface of the substrate is an amorphous VAlTiCrSi high-entropy alloy thin film.

[0037] The preparation method of this VAlTiCrSi high-entropy alloy thin film is as follows:

[0038] Using magnetron sputtering technology to prepare a VAlTiCrSi high-entropy alloy film on the surface of the substrate mainly includes the following steps:

[0039] (1) if figure 1 As shown, select V target, Al target, Ti target, Cr target, and Si target, and stack and arrange each target with a thickness of 10 mm in the order of V-Al-Ti-Cr-Si in the vertical direction from top to bottom to form One target period; then, including 12 said target periods in the vertical direction, forming a composite target.

[0040] (2) Perform mechanical grinding and polishing on the surface of the substrate, ultrasonically clean it three times with petroleum ether, acetone and alcohol, and then dry it with flowing nitrogen; then, p...

Abstract

The invention provides a VAlTiCrSi high-entropy alloy film. The film contains 14-15% of V, 12-13% of Al, 12-13% of Ti, 29-30% of Cr, and 30-31% of Si, and is deposited on the surface of the substrate by magnetron sputtering technology. Obtained in an amorphous structure. The film has high hardness and excellent corrosion resistance, and can be used for substrate protection in seawater and other environments.

Description

technical field [0001] The invention belongs to the technical field of surface treatment, and in particular relates to a VAlTiCrSi high-entropy alloy thin film and its application in seawater environment. Background technique [0002] With the formulation and implementation of the marine development strategy, marine defense has become the top priority of modern national security. Advanced marine equipment is an important guarantee for strengthening the marine defense force and a necessary support for the development of the marine economy. However, due to the particularity of the marine environment, the damage of marine equipment components is much higher than that of the land environment, and its service life is greatly reduced, especially when the underwater operation robot, seawater hydraulic transmission system, and seawater pump work in the seawater environment. in the equipment. [0003] To solve the problem of marine corrosion, traditional marine materials mostly use...
