Composite particles using ultra-fine bubbles: T20-3142
Improving laser absorption rates makes it easier to shape with 3D printers, and also enhances corrosion resistance, heat resistance, and oxidation resistance.
■Introduction of Tohoku University Technology 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, the composite particles offer advantages such as improved corrosion resistance, heat resistance, and oxidation resistance. However, both metal and ceramic particles are positively charged in water, making it challenging 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 that uses ultra-fine bubbles to produce uniform metal-ceramic composite particles with completely removed impurities, without even adding carbon nanotubes. It is expected that by shaping the obtained composite particles with a 3D printer, composite materials with improved properties can be realized.
