AI Technical Summary
The existing technology of directly adding palladium to titanium alloys has problems such as uneven composition, low yield and difficulty in process control. In particular, it is difficult to achieve accurate metering and uniform dispersion of palladium in high-end titanium alloys.
An aluminum-vanadium-palladium master alloy and its preparation method are adopted. The palladium source is loaded through a core-core flux and combined with a multi-stage homogenization technology of reaction-centrifugation-refining. The palladium element is uniformly coated on the flux surface using fluidized bed spray drying technology. The palladium element is forcibly dispersed using centrifugal force field and the problem of impurity residue is solved by combining vacuum induction melting technology.
This method achieves atomic-level dispersion and compositional uniformity of palladium, improving the corrosion resistance and mechanical properties of titanium alloys and solving the problems of uneven composition and impurity residues in traditional methods.
