Characteristics of modified layer configuration formed by micro-arc oxidation on the alloy AK12D (Al-12Si-Mg-Cu-Ni)

Oxidation resistance of graphene-coated Cu and Cu/Ni alloy.

The ability to protect refined metals from reactive environments is vital to many industrial and academic applications. Current solutions, however, typically introduce several negative effects, including increased thickness and changes in the metal physical properties. In this paper, we demonstrate for the first time the ability of graphene films grown by chemical vapor deposition to protect th...

Characteristics of the Energetic Micro-initiator Through Integrating Al/Ni Nano-multilayers with Cu Film Bridge

An energetic micro-initiator through integrating Al/Ni nano-multilayers with Cu film bridge was investigated in this study. The Cu film bridge was initially fabricated with wet etching, and Al/Ni nano-multilayers were alternately deposited on the surface of Cu film bridge by magnetron sputtering. The periodic layer structure of Al/Ni nano-multilayers was verified by scanning electron microscopy...

Effect of KOH concentration on the microstructure and electrochemical behavior of ceramic coatings formed by plasma electrolytic oxidation method on AZ31B Mg alloy

In this study, ceramic coatings were prepared on AZ31B Mg alloy by plasma electrolytic oxidation technique in electrolytes containing sodium fluoride (KF), sodium silicate (Na2SiO3.5H2O) and different potassium hydroxide (KOH) concentrations.
