Background
Titanium-based composites refer to a composite in which a reinforcing phase is added to a titanium or titanium alloy matrix. The titanium-based composite material combines the ductility and toughness of a titanium matrix with high strength and modulus of a reinforcing phase, so that the titanium-based composite material has higher strength and specific modulus than a titanium alloy, excellent fatigue and creep properties, and better corrosion resistance and high-temperature performance. At present, the titanium-based composite material is mainly applied to the fields of airplanes, missiles, satellites, ships and the like, and particularly has important application and great potential in the aspects of aerospace structural materials and aerospace engine materials. However, titanium-based composites have some drawbacks that are difficult to avoid by themselves, such as sensitivity to surface scratches, and the surface wear can seriously reduce the strength and toughness of the titanium-based composites. In order to reduce the sensitivity of the surface of the titanium-based composite material to scratches, reduce surface abrasion and prolong the service life of the material, a nickel plating coating can be formed on the surface of the titanium-based composite material by using a chemical nickel plating method, thereby achieving the purpose of protecting the surface of the titanium-based composite material. However, a layer of compact oxide film is easily formed on the surface of the titanium-based material, even if the film is removed through treatments such as oil removal and etching, the surface of the material is quickly oxidized to form a new oxide film, the chemical stability of the film is high, the surface activity of the titanium-based material is adversely affected, the plating difficulty is increased, and the bonding force between the obtained plating layer and the titanium-based material is poor. In addition, the titanium-based composite material cannot achieve a satisfactory plating effect on the surface of the titanium-based composite material by the conventional chemical nickel plating process of the titanium alloy due to the difference of two-phase electrochemical properties.
