Microhardness of sol-gel films of different texture

The effect of deposition modes - deposition rate and total content of film-forming oxides in solution - on the microhardness of sol-gel films of molar composition (%): 22 Bi ₂ O ₃ , 25 Fe < sub> 2 O ₃ , 53 TiO ₂ . The relationship between these parameters and the particle size of the dispersed phase of the film-forming solution, the degree of turbulence of its flow, and presumably with the packing density of solid particles in the film is established. It is shown that the correct selection of the deposition modes makes it possible to obtain coatings of different thicknesses with the highest possible microhardness. Tab. 4, bibliography: 8 titles.
