Embodiment Construction

[0061] The present invention will be further described below in conjunction with accompanying drawing:

[0062] figure 1 As shown, it is the state diagram of nickel plating on the surface of boron carbide particles. The position of each part must be correct, the ratio should be adjusted, and the operation should be performed as required.

[0063] The amount of chemical substances used in nickel plating is determined according to a preset range, with grams and milliliters as measurement units.

[0064] Nickel plating on the surface of boron carbide particles is carried out in a ceramic plating tank in a heated and acidic environment;

[0065] The ceramic plating tank is vertical, and the bottom of the ceramic plating tank 1 is an electric control box 2, and the upper part is a tank cover 3; an agitator 4 is arranged in the middle position of the upper part of the tank cover 3, and goes deep into the ceramic coating tank 1, by the first The fixed frame 5 is fixed; the upper le...

Abstract

The invention relates to a boron carbide particle surface nickel plating method. The surface nickel plating method is used for solving the cases of low fracture toughness, high sintering hardness, poor oxidation resistance and poor composite wettability to the interface between the boron carbide particles and metal of the boron carbide particles. By carrying out alkali washing, pickling, roughening, sensitizing, activating and surface nickel-plating on boron carbide particles, the surfaces of the boron carbide particles are uniformly plated with a nickel coating, the diameters of the nickel-plated boron carbide particles are less than or equal to 50mu m and the thickness of the nickel coating on the surfaces of the boron carbide particles is less than or equal to 30nm. After the nickel plating, the wettability and matching performance of the surfaces of the boron carbide particles are improved, the nickel plating method is an advanced boron carbide particle nickel plating method, the data are accurate and informative and the boron carbide particle surface coating is uniform in thickness and firm.

Description

technical field [0001] The invention relates to a surface nickel plating method of boron carbide particles, which belongs to the technical field of metal plating on the surface of ceramic materials and its application. Background technique [0002] Among many reinforced materials, boron carbide has constant high temperature hardness, high modulus, high wear resistance, oxidation resistance, acid and alkali corrosion resistance, especially good neutron absorption performance, and its excellent physical properties, Chemical properties and mechanical properties make it widely used in bulletproof materials, radiation-proof materials, high-temperature wear-resistant and self-lubricating materials, acid and alkali corrosion-resistant materials, cutting and abrasive tools, and nuclear reactor protection and shielding materials; but carbonization The fracture toughness of boron materials is low, and the atoms are connected by strong covalent bonds, so it is difficult to sinter and c...
