Abstract

The invention belongs to the technical field of nickel alloy metal materials, and discloses an ultralimit nickel alloy and a preparation method thereof. The ultralimit nickel alloy comprises a nickelalloy matrix, and a composite bonding layer, a composite ceramic layer, a reflecting layer, a reverse refraction layer, an insulating layer and a foam carbon layer are deposited on the surface of thenickel alloy matrix in sequence. The preparation method of the ultralimit nickel alloy comprises the step that the composite bonding layer, the composite ceramic layer, the reflecting layer, the reverse refraction layer, the insulating layer and the foam carbon layer are deposited on the surface of the nickel alloy matrix in sequence, so that the ultralimit nickel alloy is formed. According to theultralimit nickel alloy and the preparation method, the problem that existing nickel alloy can not be used at ultralimit temperature is solved.

Description

technical field [0001] The invention belongs to the field of nickel alloy materials, and in particular relates to an ultra-limit nickel alloy and a preparation method thereof. Background technique [0002] Nickel alloy refers to the alloy composed of nickel as the matrix and adding other elements. Nickel has good mechanical, physical and chemical properties, and nickel alloys formed by adding suitable elements to nickel have strong oxidation resistance, corrosion resistance, high temperature strength, and can improve some physical properties, so nickel alloys are widely used in energy Development, chemical industry, electronics, navigation, aviation and aerospace fields. Nickel alloys have played an irreplaceable role in the aerospace field due to their strong comprehensive properties such as strength, hardness, shock resistance, corrosion resistance, oxidation resistance, high temperature strength and certain physical properties. [0003] When nickel alloys are used in th...
