Abstract
Coatings of Chromium oxide were deposited on the substrate of GFRP (Glass Fibre Reinforced Polymer) composite using RF magnetron sputtering. GFRP composites exposed to different environmental condition raises new challenges toits wetting surface, so the main aim of this research work is to develop a coating on the surface of GFRP composite in super hydrophobic manner. Chromium Oxide Films were characterized by X-Ray Diffraction (XRD) analysis, Roughness tester and Ramehart Goniometer. Wettability of the GFRP composite have been studied and compared the coated and uncoated GFRP composite. In addition, Ramehart goniometer was used for determining contact angle. Contact angle values was observed 84° to 98.4° experimentally with the change in target power. The results shows that Chromium Oxide (Cr2O3) coatings displays hydrophobic nature with the rise of target power and the contact angle of 98.40 is achieved corresponding to 290 W power. The thin film exhibited hydrophobic nature with the increase in target power.
