Embodiment 1
[0021] The silicon carbide ceramic particles with a particle size of 1.0-2.0mm and 2.0-4.0mm are subjected to wettability treatment, that is, the surface of the ceramic particle is nickel-plated, and the silicon carbide ceramics with a particle size of 1.0-2.0mm and 2.0-4.0mm The mass ratio of the particles is 5:5. The process of nickel plating includes the processes of surface treatment and plating.
[0022] Surface preparation consists of the following 5 steps:
[0023] (1) Degreasing: soak in anhydrous alcohol solution for 10-35 minutes, wash with deionized water under the action of ultrasonic waves, completely degrease the surface of ceramic particles, and then dry naturally.
[0024] (2) Roughening: Under the action of ultrasonic waves, soak in hydrofluoric acid at room temperature to roughen the surface of ceramic particles.
[0025] (3), sensitization: soak for 4-6min at room temperature with a sensitization solution containing stannous chloride dihydrate and hydrochl...
