Influence of electroplating parameters on microstructure and amount of ceramic particle deposition in Ni-Co-CeO2-ZrO2 composite coating
Austenitic stainless steels are high performance steels that have various applications in solid oxide fuel cells and boiler tubes under high temperature operating conditions. The Cr2O3 oxide layer formed on the steel surface becomes unstable at high temperatures and reduces the oxidation resistance of the steel. Therefore, protection of these steels at high temperatures is essential. Therefore,...
متن کاملSYNTHESIS OF AL2O3-NI COMPOSITE POWDERS BY CO-PRECIPITATION METHOD
The synthesis of micro-sized, uniformly distributed Al2O3-15Vol% Ni powders were studied through three step co-precipitation of hydroxides mixtures from proper solution, calcination at air atmosphere and final step of calcined powders in a carbon bed. Al and Ni hydroxide and amorphous phase were first obtained from their salt’s solutions through chemical co-precipitation method by adjusti...
متن کاملElectrochemical preparation and characteristics of Ni–Co–LaNi5 composite coatings as electrode materials for hydrogen evolution
Electrocatalytic activity for the hydrogen evolution reaction on Ni–Co–LaNi5 composite electrodes prepared by electrochemical codeposition technique was evaluated. The relationship between the current density for hydrogen evolution reaction and the amount of LaNi5 particles in Ni–Co baths is like the well-known “volcano plot”. The Surface morphology and microstructure of Ni–Co–LaNi5 coatings we...
متن کاملElectrodeposited Co – Ni – Al O composite coatings 2 3
Composite coatings of Co–Ni–Al O were studied by electrolytic codeposition of Co–Ni alloys and Al O from a sulfamate 2 3 2 3 electrolyte containing Al O particles. The influence of plating parameters on the content of the co-deposited Al O particles in 2 3 2 3 Co–Ni alloys was investigated. The maximum value of co-deposited Al O can be achieved at a particle content of 80 g l in y1 2 3 bath, a ...
متن کاملA carbon nanotube-enhanced SiC coating for the oxidation protection of C/C composite materials
A carbon nanotube-enhanced SiC (CNT-SiC) coating was deposited on C/C composites to improve the oxidation resistance of C/C. The CNT-SiC coating was prepared by direct growth of CNTs on C/C surface at 700oC followed by deposition of SiC using chemical vapor deposition at 1150oC for 1 hour. SiC was deposited on the CNTs as well as the interface between CNTs and C/C, making CNTs strongly rooted o...
