Wear resistance and adherence of TiO2 sol-gel thin films

Mostrar todas las versiones(2)

The wear resistance and adherence of TiO2 films was studied; the films were synthesized by the sol-gel dip-coating technique on a grade 5 titanium alloy. Monolayer and multilayer films were deposited by varying: dip-coating Velocity, aging time of sol and the heat treatment parameters. These process...
