[Studies on Pd-Co-Ni dental casting ferromagnetic alloys. (Part II) (author's transl)].

In the previous paper, the effect of added metals such as Au, Cu, Cr, Si, etc., on the 43 Pd-27 Co-30 Ni alloy was reported. In this paper, the magnetic properties, mechanical properties, corrosion resistance and casting accuracy of the Pd-Co-Ni alloys containing Au, Zn and Si were studied. Results were as follows: 1) Mechanical properties and corrosion resistance of these alloys satisfied the standards for the dental casting alloys. 2) The corrosion resistance of the alloy containing 10 wt% Au was excellent in comparison with other specimens. 3) Casting accuracy was improved by addition of 10 wt% Au-0.1 wt% Si or 10 wt% Au-1 wt% Zn to the base 43 Pd-27 Co-30 Ni alloy.
