Abstract
Particularly titanium powder metallurgy is difficult because of both oxidation and carbonization on mixing and sintering process. In this work, the influence of some mixing methods and sintering conditions on some properties of Ti-30Mo sintered alloy was investigated. The results can be summarized as follows:
(1) Fluidizing type mixer may be useful in mixing titanium and other metal powders because it causes less contamination of oxygen, carbon and iron, and it needs short time for enough mixing.
(2) Mixing by fluidizing type mixer and sintering in non-carbonizing atomosphere in a vacuum improve the elongation and strength of Ti-30Mo sintered alloy.
(3) Corrosion resistance of Ti-30Mo sintered alloy against non-oxidizing acids is far better than that of pure titanium and is not influenced very much by oxygen, carbon and iron which are contaminated in both mixing and sintering process.
