The Effect of Carbonated Apatite Powder Size on Its Embedment into Titanium Alloy by Superplastic Deformation Process


Article Preview

The effect of carbonated apatite powder size on the carbonated apatite embedded on titanium alloy was studied. The process was conducted using superplastic deformation method at 750oC and initial pressure of 34MPa. In order to evaluate the characteristics of the resulting embedded layer, X-ray diffraction method was conducted followed with microstructure characterization. From X-ray diffraction characterization, it can be concluded that small stress layers of carbonated apatite were resulted for all samples with different initial powder size. In addition, initial powder size of carbonated apatite only significantly influences the intensity of diffraction peak for certain plane of crystal structure. From the experimental results, it can also be concluded that superplastic deformation can be used as an alternative method for the coating process of bio apatite material on titanium alloy substrate
