Bioactive glass coatings obtained by thermal spray: Current status and future challenges

Several inorganic materials such as bioactive glasses, glass–ceramics and calcium phosphates have been shown to be resorbable which make them suitable for coating bone implants. This study focuses only on glasses. These biomaterials are highly biocompatible can form a strong chemical bond with the tissues. review comprehensively covers bibliographic reports that investigated glass deposition using different thermal spray techniques. The main drawback is low adherence substrate. Some strategies favour good coats, blends, pre-heating substrate or modifying composition. characteristics of feedstock powders determinant properties coatings obtained. Porosity thickness modulated by techniques varying parameters process. degradation rate some glasses achieve kinetics similar new formation. Taking advantage its dissolution capacity, doped functional elements. While several biological studies performed materials, there has relatively little research response coated Research demonstrated opportunities this promising material enhance bioactivity
