Abstract
Titanium foam has good biocompatibility and mechanical properties, and is often used as a bone replacement material. Cobalt can improve the density of titanium foam cell walls and help improve mechanical properties. In this paper, the effect of different cobalt contents on the microstructure of titanium foam was studied. Six sets of comparative experiments with different cobalt contents were carried out. The sintering temperature was 1100 °C and the holding time was 1.5 h. The samples were subjected to metallographic and SEM inspection. Between 0 and 10%, with the increase of cobalt content, the pores gradually become denser, which helps to improve the mechanical properties. Excessive cobalt powder will lead to the closure of microscopic pores, and the connectivity between the pores becomes poor. When the cobalt content increases from 10 to 14%, the porosity of titanium foam decreases from 45% to about 20%.
