Characterization of HDH Titanium Powder for Biomaterial Applications

Article Preview

Several materials have been used as surgical implants since the 16th century. Materials can be implanted in the human body; however, the choice of the appropriate material is based on the required mechanical, physical, chemical, and biological properties. Until now two classes of metals namely stainless steel and cobalt-chromium-molybdenum alloys became known as materials for implant applications. They were considered suitable for surgical implant procedures but many researchers and surgeons were not completely satisfied with their performance. The main problem of the modern science is to find a material that perfectly restores tissues damaged after accidents or diseases. The trend of the current research in orthopedic prosthesis is based on the development of titanium alloys composed of non-toxic elements with low modulus of elasticity. Powder metallurgy techniques have beenused to produce controlled porous structures such as the porous coating applied for dental and orthopedic surgical implants which allows bone tissue grown within the implant surface, improving fixation. The development of porous metallic biomaterials associated with their biomedical applications is an important research area. To obtain a good one implant successful therapy the composition, size, form and topography of the alloys are extremely important.
