Effect of dynamical chemical etching on the porous structure parameters of superelastic medical Ti–Nb–Zr alloy foam

Аннотация

A dynamical chemical etching technique under pressure is developed and used to fabricate sintered foams based on a superelastic Ti–Nb–Zr alloy. This technique is shown to effectively control the characteristics of a porous structure and to increase the porosity and the permeability of the material.
