Fig. 25 Relationship between relative sintered density and sintering temperature of Ti64Cr specimens 50 H. Miura et al. Fig. 26 SEM micrographs of various Ti64Cr specimens Fig. 27 Stress-number curves of Ti64Cr specimens by rotating bending fatigue testing 2 Metal Injection Molding (MIM) Processing 51 Fig. 28 SEM micrograph of Ti64B specimen Fig. 5 Discussion The sintered densities of all specimens are summarized in Fig. 30. They are around 97 %TD. From the microstructure, the α-lamellae in Ti64Cr are thinner than that in Ti64.
Specimen geometry of the mold is shown in Fig. 19. Before thermal debinding, solvent debinding was conducted in vaporous heptane at 58 C for 4 h. , Japan, VHSgr 20/20/20). Each specimen was named after the sintering temperature and time used, for example, 1,350–2 means being sintered at 1,350 C for 2 h. Moreover, heat treatment was conducted for Ti64Cr specimens. Solution heat treatment was performed at 950 C for 1 h followed by aging at 560 C for 4 h. Furthermore, HIP (1,150 C for 1 h) was conducted for Ti64Cr specimens to reduce porosity.
Therefore, in order to achieve a more active life, it is essential for the patient to recognize that a prosthetic joint behaves as if it were living bone and that it has properties similar to those of bones; at the same time, it is essential that the device be designed individually (high level of freedom) in accordance with each patient’s particular skeleton, disease severity, and lifestyle habits and that it exerts its properties and functions with high performance. By themselves, the aforementioned “custom-made prosthetic joint” manufacturable with the EBM method, “prosthetic joints with a three-dimensional communicating porous structure,” and “prosthetic joints with a low elasticity modulus” are each promising as prosthetic joints with new functions; however, their combination for the realization of futuristic prosthetic joints acting as actual living bones and with an “ability to fit into the morphology of the skeleton,” a “biological ability to attach,” and “bone-like mechanical functions” is not just a dream either.
