| 摘要 |
The subject of invention is a procedure of application of an adhesive coating to a substrate, preferentially a dental prosthetic product or bone implant, by precipitation of aluminium hydroxides, formed by hydrolysis of aluminium nitride (AlN) powder in a water suspension or in a suspension containing water, and by subsequent thermal treatment. The application is intended to improve the adhesion of commercial dental and/or bone cements to the substrate which serves as a dental prosthetic product or bone implant preferentially. Sintered ceramics from tetragonal zirconium oxide, aluminium oxide, spinel, mullite or any other biocompatible inorganic material, applicable as dental material or material for bone implants, is used for the substrate, then the latter is immersed into water containing aluminium nitride (AlN) powder, where the synthesis of the coating takes place by precipitation of aluminium oxides formed by hydrolysis of AlN powder in water suspension. Then the substrate is withdrawn from the suspension, dried and exposed to thermal treatment at an elevated temperature. |
