Copper alloy containing metal ceramic coating, and preparation method and application thereof

[0049] According to glass composition 65Pb 3 o 4 : 14B 2 o 3 : 16BaO: 5SiO 2 Weigh the oxides of each component, mix the weighed powders evenly, melt and keep it at 1200°C for 2.5 hours, then pour the melt into water to obtain block glass. Block glass is crushed, and ball milled in a zirconia ball mill jar for 30 hours to obtain ceramic frit (the particle size of the ceramic frit is 0.1-40 microns);

[0050] The ceramic glass frit, metal nickel powder, and clay were mixed and ball-milled for 10 hours at a mass ratio of 1:1:0.2, and then deionized water was added to prepare a cermet water-based slurry, and the viscosity was adjusted to 10‐14s. The particle size of the nickel metal powder is 0.5-2 microns.

[0051] After degreasing the copper alloy parts of the engine, ultrasonically clean them with distilled water for 30 minutes and dry them.

[0052] The prepared water-based slurry was dispersed by ultrasonic vibration for 1 hour, and then the copper alloy parts were immers

Block glass is crushed, and ball milled in a zirconia ball mill jar for 40 hours to obtain ceramic frit (the particle size of the ceramic frit is 0.1-40 microns);

[0057] The ceramic glass frit, metallic nickel powder, and clay were mixed and ball-milled for 10 hours according to the mass ratio of 1:1.2:0.1, and then deionized water was added to prepare a cermet water-based slurry, and the viscosity was adjusted to 10‐14s. The particle size of the nickel metal powder is 0.5-2 microns.
