Cobalt-coated ceramic composite powder and preparation method and application thereof

Abstract

The invention discloses cobalt-coated ceramic composite powder. The cobalt-coated ceramic composite powder is prepared by the following steps: adding ceramic powder into cobalt-containing lyosol, carrying out stirring and foaming in the presence of a long-acting particle foam stabilizer to obtain a suspension in which ceramic foam stably exists, adding a precipitator into the suspension, carryingout gel reaction to obtain coated ceramic particle precursor powder, and reducing the coated ceramic particle precursor powder to obtain the cobalt-coated ceramic composite powder with a core-shell structure. The cobalt-coated ceramic composite powder is added into cobalt-chromium alloy powder, the cobalt-coated ceramic modified cobalt-based composite material for dentistry can be obtained and used for preparing a false tooth metal inner crown through selective laser melting forming, the coefficient of thermal expansion is low, and the cobalt-coated ceramic composite material is resistant to abrasion and good in tensile property.

AI Technical Summary

Benefits of technology

This patented technology describes an improved type of ceramics called bismuth-cocyanide (BSC) or tungsten bronze (TBC). These materials have excellent physical characteristics such as high strength at elevated temperatures compared to traditional methods like porcelain casting processes. They allow for better control on how they behave after being heat treated into solid state. By adjusting their chemical composition, BCS coatings may contain different metals depending upon its desired use. Additionally, this new modification allows for more consistently dispersible components within the resulting mixture while still providing strong cohesive force between them. Overall these technical improvements make it possible to create stronger structures made from pure ceramers.

Problems solved by technology

This patented technical problem addressed in this patents relates to developing a type of cathode ray tube display called LCD displays used in dentistry because they have excellent visual effects compared to other types like plasma screens. These devices use special glass filled with rare earth oxide crystals, making their physical structure stronger without losing weight over time. Additionally, these techniques involve combining multiple layers made from various chemical substances together to create a single body component instead of individually shaping each individual piece separately.
