Abstract:

This work is focused on the effect of spin coating technique on the mechanical properties of silicophosphate (SP) thin films belonging to system SiO2-P2O5-Nd2O3. The thin films have been obtained by spin coating technique for three rotation speeds: 2000, 3500 and 5000 rpm. A soda-lime-silicate (SLS) glass was used as a substrate. Strength characteristics (Young modulus, E, hardness, H, and plasticity index, H/E) of the SiO2- P2O5-Nd2O3 films were determined by using the dynamical nano/microindentation under Pmax=10, 30, 50, 100, 900 mN. As a result of the fulfilled studies, it was drown a conclusion: new materials with regulable mechanical properties (elastic modulus, hardness, plasticity, brittleness) can be fabricated for practical applications.
