Electrodeposited zinc alloys have long been recognised as effective barrier and sacrificial coatings for ferrous substrates. The effect of alloying zinc with, in the main, more noble metals, has produced finishes of higher corrosion resistance than simply electrodeposited zinc. In this manner zinc alloys such as zinc-nickel, zinc-cobalt and zinc-iron are routinely electrodeposited on an industr...

The P content dependencies of the nanocrystallization behaviors and high temperature magnetic properties of the Fe 54.6 Co 29.4 Si 2.8 (B 0.8ÀY P Y) 14 Nb 1 Cu 1 (Y ¼ 0, 0.2, and 0.3) alloys have been investigated. Alloys were prepared by melt spinning and subsequently annealed in an argon atmosphere to induce nanocrystallization. P addition increases primary crystallization temperature (Tx 1),...

Introduction: The process of mixing metals with non metals is called alloying, and the resulting mixture alloy. Alloys are composed of at least two elements, from which one must be metal. They are divided into alloys for fixed partial dentures-FPD (golden, golden-platinum, silver-palladium alloys, alloys for soldering and alloys for metal-ceramic dentures). Purpose: the main purpose is to inves...

A new class of magnesium alloys has been developed by dissolving large amounts of oxygen atoms into a magnesium lattice (Mg-O alloys). The oxygen atoms are supplied by decomposing titanium dioxide nanoparticles in a magnesium melt at 720 °C; the titanium is then completely separated out from the magnesium melt after solidification. The dissolved oxygen atoms are located at the octahedral sites ...

Adhesion of 4-META to Au-In alloy was improved by adding In equivalent to .15% of Au content. On the basis of the results of Au-In alloys analyzed by XPS, the present study investigated the reason why adhesion of the Au-In alloy was improved. The O 1s spectrum could be separated into three oxygen chemical states, In2O3, chemisorbed H2O, and physisorbed H2O. The amount of chemisorbed H2O decreas...

Human poo contains precious nutrients, but we flush it down the drain to become wastewater. Wastewater often pollutes rivers, lakes, or ocean. The high levels of nutrients in wastewater, primarily from human and pee, can decrease amount oxygen ocean, killing fish that eat along with other organisms. In old days, humans animals was used on farms, as fertilizer. But this is not a practical option...
