Multilayer High-Performance Ceramic Anodes
A new approach to the design of ceramic anodes that uses a thin catalytically active functional layer that has only modest electronic conductivity sandwiched between the electrolyte and a non-catalytic elecronically conducting ceramic layer that is used as the current collector is described. The anode design is flexible and allows various materials to be used in the functional and current colle...
متن کاملZinc Alloy Electrodeposition for Corrosion Protection
t is known that the protective value of zinc is partially a result of its ability to form a protective film when plated on a base metal, such as steel. The zinc is sacrificial and corrodes I preferentially to protectthe steel. Although pure zinc coating provides some degree of protection for the substrate, in a severe corrosion environment, zinc is consumed rapidly. For this reason, it is usual...
متن کاملZinc-Alloy-Plating for Corrosion Protection
Zinc represents the most effective and economic corrosion protection especially for steel base materials. Improved corrosion resistance can be achieved by alloying zinc with small amounts (around 1 Yo) of transition metal elements like Co, Ni and Fe. Zn-Fe and Zn-Co alloys containing up to 1.5 Yo of the transition metal were plated using an alkaline and acidic electrolyte respectively. Zn-Ni al...
متن کاملZinc coverage dependent structure of PdZn surface alloy.
Catalytic performances of alloy and surface alloy are sensitive to the surface structures and composition. In this paper we present an overall survey of the surface structure of Pd(111) covered with different amount of Zn using Monte Carlo simulations. We demonstrate that the composition of PdZn surface alloy is Zn coverage dependent: the surface concentration of Zn increases with the increase ...
متن کاملBiocompatibility of magnesium-zinc alloy in biodegradable orthopedic implants.
In this study, magnesium-zinc (Mg-Zn) alloy was investigated as a biodegradable orthopedic implant. MC3T3-E1 cell attachment, mineralization and osteogenic-specific mRNA expression were assessed for as measurements of the in vitro biocompatibility of Mg-Zn alloy. In vivo degradation of the Mg-Zn alloy and the accompanying new bone formation in the femoral marrow cavity were analyzed by scanning...
