TI  - An experimental evaluation of the three types of corrosion, passivation, pitting, and uniform corrosion, by electrodeposited chromium-nano diamond composite coating on porous materials
AB  - The addition of nanoscale particles to metal coatings results in nano composite coatings, a brand-new class of materials with improved hardness, wear, and corrosion resistances. Pre-alloy metal powder metallurgy samples were electrolytically coated with pure chromium and Cr-ND in this work (Chromium-nano diamond). The effects of the co-deposited ND particles on the passivation, pitting, and uniform corrosion behavior of the chromium coatings were experimentally investigated and contrasted with pure chromium coating and non-coated specimens. Under 3.5%wt. NaCl solution, the corrosion behaviors of the samples were examined using the measuring techniques of Polarization Resistance, Cyclic Voltammetry, and Electrochemical Impedance Spectroscopy. Additionally, characterization tests were performed using an optical microscope, a SEM (Scanning Electron Microscope), EDS (Energy Dispersive X-Ray Spectroscopy), XRD (X-Ray Diffraction), and AFM (Atomic Force Microscope). As a result of the ND particles being incorporated into the chromium matrix, it was shown that when compared to pure chromium coatings and non-coated specimens, Cr-ND coatings demonstrated a clear improvement in corrosion behavior.
