Microhardness Of Sol-Gel Films With Various Textures

The effect of the regime of deposition (the rate of the deposition and the total content of film-forming oxides in the solution) on the microhardness of sol-gel films with a molar composition of 22% Bi2O3 25% Fe2o3, and 53% TiO2 is described. Then mentioned parameters are shown to be connected with the particle size of the disperse phase of the film-forming solution, the degree of turbulence of its flow, and . Supposedly, with the packing density of the solid particles in the film. It is shown that a correct choice of the regime for depositing the coating provides coatings of various thicknesses that possess maximum possible microharness.
