Hysteretic Behavior of Twin Boundary Peak Due to Precipitation in Co-Ni-Cr alloy

Diffraction studies on Ni-Co and Ni-Cr alloy thin films

Molecular dynamics simulation of Al–Co–Cr–Cu–Fe–Ni high entropy alloy thin film growth

Evaluation of marginal and internal gaps of Ni-Cr and Co-Cr alloy copings manufactured by microstereolithography

PURPOSE The purpose of this study was to evaluate the marginal and internal gaps of Ni-Cr and Co-Cr copings, fabricated using the dental µ-SLA system. MATERIALS AND METHODS Ten study dies were made using a two-step silicone impression with a dental stone (type IV) from the master die of a tooth. Ni-Cr (NC group) and Co-Cr (CC group) alloy copings were designed using a dental scanner, CAD soft...

Effect of TiO2 nano-particles on corrosion behavior of Co-Cr alloy coatings in simulated body fluid

Co-Cr and Co-Cr/nano-TiO2 coatings were electrodeposited from Cr(III) based baths. The effect of TiO2 nano-particles incorporation on the morphology, structure, crystallite size, and preferred orientation was studied. Corrosion behavior of the composite coating was also investigated by means of polarization and electrochemical impedance spectroscopy techniques in Hanks’ si...

SYNTHESIS 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...
