We have performed Brillouin light scattering experiments to study the elastic properties of Cr films deposited on soda-lime glasses by using Ar-ion assisted deposition techniques. The elastic constants of the films increased as the ion-current density employed during the film deposition increases and they approached to the values of bulk Cr. The best fit values of the elastic constants of the films manufactured with ion current density of $400\muA/cm^{2}$are $c_{11}=296, c_{13}=83, c_{33}=289$, and $c_{55}=c_{44}=108(\times10^9/N/m^{2}}$ and these are 5% lower than those of bulk Cr in hexagonal symmetry. metry.
