Al2O3 + TiO2 thin film made by electrostatic spray deposition

In this work electrostatic spray deposition process was used to deposit thin Al2O3 + TiO2 ceramic thin film on X10CrAlSi18 steel from colloidal suspension of TiO2 powder in Al2O3 precursor solution. The precursor was 3% solution of Al2(NO3)3 in ethanol. An influence of the thermal treatment after film deposition on protective properties against high temperatures and film endurance were investigated. The resistance against thermal cycles and dynamic impacts were tested. Performed investigations showed that the best protective properties had the Al2O3 + TiO2 film sintered at 1000°C.
