Abstract

Language:

The nanoparticles of Elaeis guineensis (oil palm) kernel shell ash were developed into a recipe for fabricating composite coatings on gas turbine blades using an electrodeposition technique. To prepare the electrodeposition bath, 100 g/L ZnCl₂, 5 g/L thiourea, 15 g/L boric acid, and 100 g/L KCl were used, while the composite coating recipes contained 0, 5, 10, 15, 20, and 25 g/L of the nanoparticles. This work analyzes the various weight percentages in the electrolyte with the aim of investigating and determining the effectiveness of each composite coating through measurements of coating thickness, hardness, surface roughness, X-ray diffraction (XRD), electrical conductivity, tribology, and microstructure. The results show that the composite coatings improve gas turbine blade performance, with the 20 g/L composition giving the most effective performance. The decrease in performance beyond this composition is attributed to excessive electrolyte viscosity, which hinders electron flow during electrodeposition, a behavior consistent with previous studies.
