Embodiment 1
[0018] A corrosion-resistant cobalt alloy with excellent casting properties for surface craft and submarines. In terms of weight percentage, the composition of the alloy is Ba:1.0wt.%, In:4.0wt.%, Ag:1.5wt.%, W:0.4wt.%, Bi:2.0wt.%, V:0.4wt.% , Ge: 2.0wt.%, Re: 0.2wt.%, and the balance is cobalt. The above-mentioned corrosion-resistant cobalt alloy with excellent casting performance for surface boats and submarines comprises the following steps: adding the above proportioned raw materials into an induction furnace under an argon environment, and using a graphite crucible; melting at 1600 degrees Keep warm for 10 minutes, stir evenly with high-frequency induction furnace electromagnetically; after stirring evenly, keep warm at 1600 degrees for 1 minute and cast out of the furnace; alloy casting uses a steel mold with a diameter of 50-100mm, and uses water cooling to cool down. Heat the obtained ingot at room temperature to 1650-1700 degrees and keep it warm for 10 minutes; then...
