In this paper a new method for the fabrication of porous commercially pure titanium coatings with sacrificial polymer beads is presented. Two coating processes are employed, plasma spraying and vacuum furnace sintering. Microstructure and properties of plasma sprayed and sintered coatings are examined. Results demonstrate that spherical pores are produced in sintered coatings (shown in figure) and flat circular pores are produced in plasma sprayed coatings.
