Laser forming method of Cr3C2-NiCr composite material component
The invention relates to a laser forming method of a Cr3C2-NiCr composite material component. Selected raw material powder comprises, by weight percent, 3.28% to 4.80% of graphite, 30.25% to 38.53% of Cr, 1.56% to 3.85% of Mo, 0.38% to 0.71% of rare earth oxide and the balance Ni. The laser forming...

| description | The invention relates to a laser forming method of a Cr3C2-NiCr composite material component. Selected raw material powder comprises, by weight percent, 3.28% to 4.80% of graphite, 30.25% to 38.53% of Cr, 1.56% to 3.85% of Mo, 0.38% to 0.71% of rare earth oxide and the balance Ni. The laser forming powder is conveyed quantitatively through a multi-hopper conveying system, four powder feeding devices of the multi-hopper conveying system are all connected with one common laser head through powder feeding pipes; a four-pipe coaxial laser head is adopted in laser forming, and through control over the powder conveying system and the laser head, the inner and outer gradient layered structure of the Cr3C2-NiCr component can be achieved, and the breaking toughness of the Cr3C2-NiCr component can reach more than 70% of a Ni-based alloy. |
