Adhesion on Gate Surface: A Case Study on Role of Surface Roughness

摘要

Precise control of friction and wear is very important for the energy efficiency and sustainability in hydraulic systems. In the present study, the effect of tribological property- Surface roughness, is observed on the bonneted Gates of990 MWHydropower Generation Project. The surface roughness of the gate was quantified using Visual Surface roughness comparator. The prescribed thickness of 0.5 mm of Brushable ceramic, to be applied on the Gate surface being checked using the wet film thickness gauge.The study shows - when the composite based coating was applied onto surface with specified surface roughness gives 3-4 times long lasting protection than traditional approach, to the gate from physical phenomenon's and in turn it reduces generation cost.
