This is the abstract version of the work. For access to the fulltext, kindly access the publisher's website.The inter-relationships between geometrical properties, microstructural characteristics and corrosion resistance on one hand and laser-material interaction parameter (a) on the other hand are examined. A laser-material interaction parameter within the range of 599 = a = 400 J.s g-1 mm-1 imparted optimum characteristics of microstructure, microhardness and corrosion resistance. The consolidation mechanism of the coatings indicates that this parameter ensures the formation of a double ‘burn-in’ macrostructure into the substrate which imparts non-porous, crack-free and a fine interfacial microstructure. This study provides guidance in designing Inconel 625 coatings of desirable microstructures and corrosion resistance.enCorrosion resistanceDilutionConsolidation mechanismInconel 625 coatingsIPG YLS 5000 fibre laserLaser claddingLaser-materials interaction parameterMicrostructure evolutionArticleOlakanmi, E., Malikongwa, K., Nyadongo, S., Hoosain, S.
