内容記述 | Demands of medical implants such as artificial hones increase as an aged society is coming. A medical implant can be substituted for original tissue only when it satisfies both mechanical properties and biocompatibility. Since such material is not found in nature, hybrid materials are promising and have been developed. In the previous paper, coatings of hydroxyapatite (HA) were deposited on titanium substrate by graded plasma spraying, but the properties of obtained coatings were inferior to those of bone. In this paper, two successive processes were conducted as a grounding of spraying. First stage is a formation of titanium compound which is processed chemically to titanium by NaOH and have high adhensive strength to both titanium and HA. Second stage is HA coatings self-deposited by dipping titanium in Ringer's solution. On these films, 50 μm thickness coating of HA was carried out by plasma spraying in vacuum chamber. It was clarified through the observation of self-deposited surface with SEM and AFM that increase of self-deposit time resulted in improvement of adhensive strength. Self-deposited surface becomes rough in microscopic order but keeps smoothness in mesoscopic, when self-deposited particles of HA grow and cover over the substrate surface. Such surface is easy to bond the sprayed particles by anchor effect as well as chemical affinity and results in increase in adhensive strength. | |||||
