Composite electroforming preparing process for nano silicon carbide particle reinforced nickel base composite material

Abstract

The composite electroforming process of preparing nanometer silicon carbide particle reinforced nickel base composite material has electrolytic nickel block as anode material, stainless steel sheet as cathode deposition body, silicon carbide particle of 10-50 nm as reinforcing particle and ammonium cetyl bromide as co-deposition promoter. Through mixing silicon carbide particle and co-deposition promoter solution through stirring, pouring the mixed solution into electroforming solution of nickel amino sulfonate, applying DC voltage while stirring the electroforming solution to make nickel ion and reinforcing particle deposit together onto the cathode mother body and stripping the composite electroformed layer, integrated nanometer silicon carbide particle reinforced nickel base composite material is produced. The produced composite material has high hardness, high strength, high ductibility and relatively great thickness, and may be used as functional structure material.

Description

technical field

[0001] The invention relates to a method for preparing a nickel-based composite material, in particular to a method for preparing nickel-based composite materials reinforced with silicon carbide particles with nanoscale particle diameters by using a composite electroforming method, which belongs to the technical field of composite electroplating. Background technique

[0002] Using composite electroplating technology to prepare silicon carbide particle-reinforced nickel-based composite materials can endow metallic nickel with higher hardness, better wear resistance, and corrosion resistance. It provides a great opportunity for changing or adjusting the mechanical, physical, and chemical properties of metallic nickel. Great possibilities and variety. However, composite electroplating technology is mainly for surface treatment. In most cases, only a layer of composite material is plated on the surface of parts. The required thickness is thinner.
