Abstract

Purpose - The purpose of this study is to determine the effect of dimpled texture on ceramic coating towards erosion wear. Design/methodology/approach - The methodology of this experiment is based on ASTM G73, which is for erosion test for rotating apparatus. Mild steels samples were coated with alumina titania via the plasma spray method, and surface modification was done by producing different dimple densities using laser surface texturing. Two mediums were used: seawater environment and slurry environment. Findings - Dimples of 150 μm diameter and 50 μm depth have proved to be successful in entrapping wear debris and other foreign materials during the erosion test. It was clearly noted that coatings with the highest number of dimples with 43 per cent had significantly improved the microhardness of the coated mild steels by twofold. Originality/value - All this while, texturing was done only on substrate material. None was done on ceramic coating.
