Conclusions
-
1.
The scale resistance of Ti−Sn−O alloys at 700–1000o with up to 10%Sn and with 0.35% O indicates that the presence of oxygen in Ti−Sn alloys lowers the oxidation rate at all temperatures tested. However, the oxidation rate still tends to increase with the tin content of the alloy.
-
2.
The oxidation mechanism of binary Ti−Sn and ternary Ti−Sn−O alloys at these temperatures is the same. An increase in the strenghth of interatomic bonds due to solution of oxygen in binary solid solutions of Ti−Sn slows down the diffusion of titanium during oxidation and explains the increase in the scale resistance of Ti−Sn−O α solid solutions.
