▎ 摘　　要

NOVELTY - Diamond-brazing filler metal comprises 45-55 pts. wt. copper, 8-15 pts. wt. silver, 25-40 pts. wt. zinc, 2-3 pts. wt. nickel, 0.5-1 pts. wt. carbon material, 1-2 pts. wt. magnesium carbonate and 0.2-0.3 pts. wt. colophony. USE - Material is used for braze welding of diamond used in grinding tool technology. Uses include but are not limited to grinding tool, grinding tool and grinding tool. ADVANTAGE - The diamond brazing material has excellent interface performance, so that the welding product has good structure performance, structural stability and strength performance, and high brittleness, and effectively improves the performance of the brazed filler metal, so as to obtain a significant improvement in the structural stability, strength performance and mechanical strength of the welding material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the method for preparing diamond brazing material, which involves: i.paving the graphene oxide powder in the reaction chamber and vacuumizing to 5Pa introducing mixed gas of methane and Ar gas adjusting the mixed gas pressure to be 100-500Pa then raising the working temperature to 500-1000degrees Celsius, after reaching the working temperature opening the radio frequency power supply; ii.adjusting the radio frequency power to 150-200W, processing for 10-30 minutes, cooling with the furnace and then mixing with magnesium carbonate powder and rosin powdergranulating into light material particles in the 80-100degrees Celsius, the powder is formed by mixing copper powder silver powder zinc powder and nickel powder as core material the light material particles as the outer layer is covered outside the core material obtaining the brazing material.
