บทคัดย่อ

As the bone fracture is now considered the second most serious disease in the world, a huge number of orthopedic devices for bone healing is being developed. However, there happened to be a number of incidents in which the orthopedic plates were broken inside the body due to inadequate strength. The present study aims to investigate the effects of Fine Shot Peening (FSP) conditions on performances of orthopedic plates and screws. In this research, there are 3 types of medical alloys to be studied namely SUS316 alloy, Ti6Al4V alloy and Ti6Al7Nb. In FSP process, 40 and 80 μm diameter of silica media was selected and utilized. FSP was carried out under the pressure of 0.5 MPa in Nitrogen atmosphere. The study shown that Ti6Al4V alloy with FSP media diameter of 80 μm resulted in 11% increment of bending strength and 40% increment of surface hardness. Regarding the orthopedic screw, the result shown that after applying FSP, the pull out strength from bone could be increased above 76%. © 2019 Trans Tech Publications Ltd, Switzerland.
