Abstract

This invention relates to a thin and texturized film that can be applied onto a non-smooth surface to improve hardness, corrosion resistance and wear resistance properties of the surface while maintaining the underlying profile of the non-smooth surface. An additive overlaying process can be employed to produce the thin and texturized film on the non-smooth surfaces without substantial alteration or degradation of the underlying surface texture or profile of the non-smooth surfaces so as to sufficiently preserve the underlying surface texture or profile. The thin and texturized film fully covers the non-smooth in a uniform manner and maintains the surface profile.
