The in vitro response in simulated body fluid (SBF) of silicate glass coatings on Ti6A14V was evaluated. Glasses belonging to the SiO2-CaO-MgO-Na2O-K2O-P2O5 system were used to prepare 50-70 m thick coatings on Ti6Al4V, employing a simple enameling technique. Glasses with silica content higher than 55 wt% can be used to prepare coatings that do not crack or delaminate and exhibit good adhesion ...

Pyroxene glass-ceramic enamels based on combinations of blast furnace slag and some additives were produced investigated. The batch compositions technological regimes enameling developed to produce high temperature protective coatings for carbon steel (ASTM 1010/1008). composition raw materials was selected match the values thermal expansion coefficients coating (~11?10?6 K?1) metal substrate (...
