Titanium alloy having improved corrosion resistance and strength
A titanium alloy containing carbon with and without addition of silicon exhibiting improved corrosion resistance and mechanical strength as compared to commercially pure ASTM grade 2 titanium or PGM-alloyed ASTM grade 7 titanium.
1 . A titanium alloy exhibiting improved corrosion resistance as compared to commercially pure ASTM grade 2 titanium, said alloy utilizing carbon as the primary alloying element to effect said improved corrosion resistance.
2 . The titanium alloy of claim 1 wherein the alloy comprises a carbon content of 0.2-4 weight percent.
3 . The titanium alloy of claim 1 wherein the alloy comprises a carbon content of 0.5 to 2 weight percent.
4 . The titanium alloy of claim 1 wherein the said alloy comprises commercially pure ASTM grade 2 titanium, alloyed with said carbon.
5 . A titanium alloy exhibiting increased strength as compared to commercially pure ASTM grade 2 titanium, said alloy comprising carbon as a primary alloying agent effecting said improved strength.
6 . The titanium alloy of claim 5 wherein the alloy comprises carbon of 0.2 to 4 weight percent.
7 . The titanium alloy of claim 5 wherein the alloy comprises carbon of 0.2 to 2 weight percent.
8 . The titanium alloy of claim 5 wherein the said alloy comprises commercially pure ASTM grade 2 titanium, alloyed with said carbon.
9 . The titanium alloy of claim 5 including silicon.
10 . The titanium alloy of claim 5 including silicon of 0.1 to 0.5 weight percent.
