Study of Corrosion Resistance of Electro-Deposition Ni-Cbn Composite Coatings

Development of Corrosion Resistant Zn-Ni-TiO2 Composite Coatings

The Zn-Ni-TiO2 composite coatings were developed on mild steel by electrodeposition method. The bath constituents (ZnSO4.6H2O, NiSO4.6H2O, TiO2, thiamine hydrochloride) and operating conditions (temperature and pH) were optimized by Hull cell method, for peak performance of the coating against corrosion. The coatings were prepare...

STUDY OF CHARACTERIZATION AND CORROSION RESISTANCE OF NIP/NANO-DIAMOND ELECTROLESS COMPOSITE DEPOSITION

Ni-P Electroless coatings provide appropriate resistance to wear and corrosion. Co-deposition of particles between layers can improve their properties, especially general corrosion and erosion-corrosion behavior by means of nano diamond as reinforcing particles. In this study Ni-P/nano diamond composite deposition were deposited on steel substrate. Structure of the coatings and corrosion r...

STUDY ON CORROSION BEHAVIOR OF COBALT NANO COMPOSITE COATINGS

Metal matrix nano composite coatings possess enhanced properties such as corrosion and wear resistance. This paper aims to study the corrosion behavior of pure Co and Co-BN nano composite coatings deposited with different particles concentration (5-20 g L-1) on copper substrates using electroplating technique. Morphology and elemental compositions of the coatings were investigated by means of s...

Study of the Corrosion Resistance of Ni/CeO2 Composite Coatings Electrodeposited on Carbon Steel in Hydrochloric Acid

The phase formation of Ni-Ce composites onto a carbon steel electrode was investigated using electrochemical deposition. The anticorrosive properties of composite coating in 0.1 mol L HCl solution were studied by Tafel polarization and electrochemical impedance spectroscopy (EIS). Incorporation of CeO2 particles into the Ni matrices was found to improve corrosion resistance of pure Ni coatings....
