Partially open cell Ti-6Al-2Co ternary alloy foams with a range of size and volume fraction of spacer particle

•Partially open cell Ti6Al2Co ternary alloy foams was prepared using range of particle size and volume fraction of sapcer particles.•The decrease of size and increase of vol% of spacer particles decreased the plateau stress, modulus, toughness and microhardness.•The mechanical properties followed power laws and constants of proportionality, and exponent values were found in the close agreement with the published data.•Corrosion rates (mmpy) have been increased with the decrease of particle size of spacer particles.
