Abstract

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.
