Outline of Final Research Achievements

Powder jet depositions (PJD) is a precise mechanical coating technique that uses ultrafine particles accelerated to several hundred meters per second by a jet flow of a carrier gas to fabricate functional surfaces with high efficiency. PJD is performed at room temperature and atmospheric pressure, which enables it to be used with HA particles for the creation of HA films. The TiO2-HA particles in the deposited film were densely packed, the maximum and average film thickness were about 56µm and 28µm, respectively. There were no significant differences in the maximum and average thickness before and after thermal cycling. Vickers hardness was 371.39+/-20.68 and bonding strength was 14.78+/-4.44. There were also no significant differences in the hardness and the bonding strength before and after thermal cycling. The thickness, hardness and bonding strength of TiO2-HA films were almost equal to that of HA films created by PJD process.
