Surface Modification of Biomedical Implant by Aerosol Deposition |
| 초록 |
There has been a great thrust towards development of calcium phosphate-based surface coatings on various metallic and nonmetallic substrates for load bearing implant applications in dental and orthopedic fields. Although various coating techniques have been extensively studied by many researchers, there still remains a challenging problem in the development of optimum coating materials and fabrication technologies in terms of biological response, mechanical integrity and deposition rate of coating. Aerosol deposition (AD) is a newly developed coating method which is capable of depositing dense ceramic coating layer on various substrates such as metals, ceramics and plastics at room temperature. AD has received considerable attention due to its low processing temperature, high adhesion strength and precise control over the composition and thickness of the coatings. Particularly, the aerosol-deposited HA coatings are mainly composed of nano-sized grains which are quite similar to the apatite nanocrystals found in natural bone with regard to size and crystal structure. These characteristics make AD very suitable for the fabrication of bioactive calcium phosphate-based coatings in biomedical applications. In this study, we have shown that bioactive ceramic coatings with different surface chemistry and surface morphology can be successfully deposited on metallic and plastic substrates by AD. In addition, the antibiotic-containing HA composite coatings were fabricated without the deterioration of antibiotic efficacy, offering the possibility of achieving drug delivery devices using AD. |
