Abstract
Electro-chemical dissolution of steel was examined as a new space-holder for creating porosity in sintered titanium. Steel was removed from the sintered Ti-Fe composites in an electrolytic cell with a cylindrical titanium sheet acting as the cathode. Excellent edge retention of the cavity created by dissolution of high-carbon steel wire and the uniformity of the cavity diameter, demonstrates that titanium did not dissolve during the steel dissolution as a result of cathodic protection. Titanium foams produced by dissolution display highly elongated pores with constant diameter and good interconnectivity. The experiment also illustrate the feasibility of creating three-dimensional open porosity in foams with highly regular spherical porosity and low relative density, filling the interstices with fine titanium powders.
