Properties of Tic/Tib Modified Zn–Tic/Tib Ceramic CompositeudCoating on Mild Steel

摘要

Researches in the area of zinc coatings on steeludare rather unending because of the unique properties andudthe very low cost that it offers. In this study, an attempt touddevelop a compact and structurally modified coating thatudwill work against chemical and mechanical deteriorationudwith the help of Zn–Tic/Tib was studied. Scanning electronudmicroscope and atomic force microscope were used toudstudy the surface morphology, the topography, and theudsurface adherence properties of the coatings. Micro-hardnessudof the deposited substrate, the electrochemicaludbehavior and the corrosion properties of the deposits wereudinvestigated by means of high impact diamond Dura scanudmicro-hardness tester and gravimetric method. From theudresults, the deposition of Zn–Tic/Tib composite particlesudshowed good protection against corrosion and alsoudimproved the hardness values. Hence, Zn–Tic/Tib alloyudcoating on mild steel can be used to improve the propertiesudof mild steel.
