Embodiment 1
[0023] 65wt% silver, 30wt% copper, and 5wt% palladium will be accurately weighed, wherein silver and palladium are bulk materials that have been smelted once.
[0024] (1) First put silver and copper into the crucible of the vacuum melting furnace, and vacuumize to 6.5×10 -2 After Pa, power up and heat up, and the power is slowly delivered from low to high until it is completely melted and clear; after refining, it is cast, and samples are taken for analysis and testing, and the splashing performance is qualified;
[0025] (2) Place the silver-copper alloy in a vacuum induction melting furnace and add palladium, and vacuumize to 2×10 -2 Pa, start power supply; power on and melt: power on and heat up, the power is slowly delivered from low to high, until it is completely melted and clear; power off, keep it for 20 minutes, wait for solidification; power on again to heat up, until it is completely melted and cleared; warm up and cast ; After casting, wait for cooling to come ou...
Embodiment 2
[0027] 58wt% silver, 32wt% copper, and 10wt% palladium will be accurately weighed, wherein silver and palladium are bulk materials that have been smelted once.
[0028] (1) First put silver and copper into the crucible of the vacuum melting furnace, and evacuate to 6.9×10 -2 After Pa, power up and heat up, and the power is slowly delivered from low to high until it is completely melted and clear; after refining, it is cast, and samples are taken for analysis and testing, and the splashing performance is qualified;
[0029] (2) Place the silver-copper alloy in a vacuum induction melting furnace and add palladium, and vacuumize to 5×10 -2 Pa, start heating with electricity; turn on electricity to heat up, slowly transfer power from low to high, until it is completely melted and clear; power off, keep it for 18 minutes, and wait for solidification; send electricity to heat again, until it is completely melted and cleared; raise the temperature and cast; after casting Waiting for...
Embodiment 3
[0031] 65wt% silver, 20wt% copper, and 15wt% palladium will be accurately weighed, wherein silver and palladium are block materials that have been smelted once.
[0032] (1) First put silver and copper into the crucible of the vacuum smelting furnace, and evacuate to 6.8×10 -2 After Pa, power up and heat up, and the power is slowly delivered from low to high until it is completely melted and clear; after refining, it is cast, and samples are taken for analysis and testing, and the splashing performance is qualified;
[0033] (2) Place the silver-copper alloy in a vacuum induction melting furnace and add palladium, and vacuumize to 4.5×10 -2 Pa, start heating with electricity; turn on electricity to heat up, slowly transfer power from low to high, until it is completely melted and clear; power off, keep it for 18 minutes, and wait for solidification; send electricity to heat again, until it is completely melted and cleared; raise the temperature and cast; after casting Wait fo...
