Embodiment 1
[0026] Prepare the aluminum bronze QAl9-4 / stainless steel 1Cr18Ni9Ti bimetallic composite material, machine the stainless steel 1Cr18Ni9Ti into a cylinder with a size of Φ30mm×50mm, and prepare the aluminum bronze QAl9-4 material with a size of Φ30mm×60mm;
[0027] Soak stainless steel 0Cr18Ni9Ti in 10% nitric acid alcohol for pickling, pickle for 1min, then wash with alcohol and store in kerosene for later use;
[0028] Wash the pickled stainless steel 1Cr18Ni9Ti with alcohol to wash the surface oil stains, and then put it into a physical vapor deposition furnace for vacuuming. When the vacuum degree reaches 6.67×10 -2 After Pa, deposit CuNi10 material on the surface of stainless steel 1Cr18Ni9Ti for 15 minutes;
[0029] Put the surface deposited stainless steel 1Cr18Ni9Ti in the corundum crucible, and then put the aluminum bronze QAl9-4 material on the stainless steel 1Cr18Ni9Ti, put the corundum crucible ZRS-18Q microcomputer program-controlled vacuum high-temperature sinte...
