Composite particles using ultra-fine bubbles: T20-3142
Improving laser absorption rates makes it easier to create shapes with 3D printers, and also enhances corrosion resistance, heat resistance, and oxidation resistance.
Introduction of Tohoku University Technology (T20-3142) To reduce the amount of energy required to melt metal particles in 3D printing, it is effective to disperse nm-order ceramic particles on the surface of the metal particles, thereby increasing the surface area as metal-ceramic composite particles. Additionally, composite particles have the advantage of improved properties such as corrosion resistance, heat resistance, and oxidation resistance. However, there is a challenge in that both metal particles and ceramic particles are positively charged in water, making it difficult to produce uniform composite particles. The inventors have previously succeeded in creating composite particles using carbon nanotubes without the use of agents for surface charge adjustment or binders. This invention relates to a technology for producing uniform metal-ceramic composite particles that are completely free of impurities without even adding carbon nanotubes, by using ultra-fine bubbles. It is expected that by shaping the obtained composite particles with a 3D printer, composite materials with improved properties can be realized.
