Coating of ZrO2 supports with a biological glass.
The possibility of obtaining a good bioactive coating on biomedical devices made with zirconia ceramic was considered. Yttria partially stabilized zirconia was used to produce suitable substrates. The obtained adhesion was good (66+/-13 MPa) and encouraging for biomedical applications. Small microcrystals formed inside and on the surface of the glass layer. These microcrystals transformed the glass into a glass-ceramic. An accurate investigation of the nature of this microcrystal formation was carried out to verify its compatibility with the planned biomedical applications.
