Abstract

The invention belongs to the technical field of preparation, and discloses an ultralimit ferroalloy and a preparation method thereof. The ultralimit ferroalloy comprises a ferroalloy 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 the ferroalloy matrix in sequence; the composite bonding layer comprises a bonding layer deposited on the surface of an aluminium alloy matrix, and a precious metal layer deposited on the surface of the binding layer; and the composite ceramic layer comprises a ceramic layer A and a ceramic layer B. According to the ultralimit ferroalloy, through deposition of a plurality of coatings on the surface of the ferroalloy matrix,the service temperature of the ultralimit ferroalloy can be increased to 100 DEGC-500 DEGC higher than the melting point of the original ferroalloy matrix, so that the application of the ferroalloy in ultralimit environment is achieved. The ultralimit ferroalloy provided by the invention has excellent high-temperature mechanical and chemical stability, and can be used under the condition of exceeding the melting point of the ferroalloy matrix; and the application range is expanded.

Description

technical field [0001] The invention belongs to the technical field of ferroalloy material preparation, and in particular relates to an ultra-limit ferroalloy and a preparation method thereof. Background technique [0002] As an important metal material today, ferroalloy is the most important and most important metal material used in engineering technology.
