Dental 3D printed cobalt-chrome-molybdenum alloy powder containing Ta
3D printing is a technology based on digital model files, the use of powder metal or plastic and other adhesive materials, through the way of layer by layer printing to construct objects, with rapid forming, short processing cycle, easy to process personalized objects and complex shape objects, so it is particularly suitable for the dental repair field dental crown, bridge, bracket and other production. In order to ensure the quality of 3D printing, 3D printing powder material requirements: high purity, low oxygen content, good fluidity; The grain shape has high sphericity, small particle size and narrow distribution. For dental 3D printing alloy powder, it should also have good gold and porcelain bonding force, corrosion resistance and high temperature barbecue ability.
Cobalt-chromium-molybdenum alloy has good biocompatibility, excellent mechanical properties and corrosion resistance, and is an alloy powder commonly used in existing dental 3D printing for the production of dental crowns, dental Bridges, supports and other restorative parts, but the existing cobalt-chromium-molybdenum alloy powder has poor gold-porcelain bonding performance, oxygen content needs to be further reduced, and thermal stability and fluidity need to be further improved.
