“…10 Slurry erosion in hydropower plants is a major concern as it reduces the efficiency and life span of various mechanical components such as turbine blades, labyrinth seals and guide vanes. 16,17 In this investigation, the degraded Francis turbine runner blade observed at Nathpa Jakhri hydropower project, Shimla, Himachal Pradesh, has been discussed. It has been reported that due to the extensive presence of silt particles during the rainy season, the various components of the turbine get damaged.…”

This work presents a novel insight into slurry erosion behavior of thin layer of carbon fiber–epoxy-based composite adhered on 16Cr5Ni steel (adhesive coating) to evaluate its viability as a feasible candidate for slurry erosion applications. Experiments were conducted on a laboratory-developed slurry erosion test rig under accelerated conditions to study the effect erosion parameters namely slurry concentration, impact angle, and impact velocity. Under all the experimental conditions, adhesive coating showed better slurry erosion resistance in comparison with bare 16Cr5Ni steel specimens. Scanning electron microscopy analysis revealed that in the case of bare 16Cr5Ni steel; ploughing, micro-cutting, crater, plastic deformation, and lip formation were identified as main mechanism responsible for slurry erosion, whereas in the case of adhesive coating; pitting, cracking, fracturing, and shearing-off were found to be mainly responsible for material loss. It implies that adhesive coating showed a brittle mode of failure under slurry erosion conditions, whereas 16Cr5Ni steel exhibited a ductile mode of erosion.
