New PtMg Alloy with Durable Electroalytic …
Polycrystalline alloy electrodes of Pt with alkaline earth metals (Ca, Sr, and Ba) have been shown to exhibit enhanced electroalytic performance for oxygen reduction reaction (ORR) relative to Pt electrodes. The large oxophilicity of the alkaline earth metals makes it challenging to synthesize such alloys. Here, we synthesize a carbon-supported platinum–magnesium (PtMg) alloy with

Corrosion of Aluminum and Its Alloys: Forms of Corrosion …
Corrosion is the reaction of aluminum with water and the subsequent deterioration of its properties. Corrosion, by definition, is a slow process, requiring days or years to occur to a noticeable extent, as opposed to similar electrochemical reactions such as etching, brightening, or anodizing which occur in …
Corrosion resistance of Nickel alloys in hydrogen chloride
At lower temperatures where moisture condenses, the hydrochloric acid produced by reaction with water is severely corrosive. It should be kept in mind that there are several factors and that even nominal magnitudes of additives may influence the tenacity and vapor pressure of the security corrosion scales.

Precipitation and Hardening in Magnesium Alloys | …
2012/7/21· Magnesium alloys have received an increasing interest in the past 12 years for potential appliions in the automotive, aircraft, aerospace, and electronic industries. Many of these alloys are strong because of solid-state precipitates that are produced by an age-hardening process. Although some strength improvements of existing magnesium alloys have been made and some …
Chemical Reactivity - Michigan State University
Reaction of magnesium or zinc with small amounts of 1,2-dibromoethane has been used to activate the metal surface for subsequent reaction with a more sluggish alkyl halide. Ethylene gas is the only organic product formed in this activation stage.
Reaction of Aluminum with Water to Produce Hydrogen
the reaction of magnesium-aluminum mixtures with sea water (2). More recently, there has been renewed activity, reflected in a nuer of publiions and patents directed at the production of hydrogen through reactions between aluminum-based metals and

Aluminum: Chemical reactions | Pilgaard Elements
Aluminium reacts with oxygen, forming a protective layer of alumnium(III) oxide that prevents further reaction with oxygen. Like magnesium, aluminium burns in oxygen with a brilliant white flame. The product in this reaction is also alumnium(III) oxide. 4 Al (s) + 3 O 2 (g) 2 Al 2 O 3 (s)
hodic processes - Corrosion
Electrochemical reactions occurring during the corrosion of magnesium in neutral water The change in the concentration of hydrogen ions or increase in hydroxyl ions can be shown by the use of pH indiors which change color and thus can serve to demonstrate and loe the existence of surfaces on which the hodic reactions in corrosion are taking place.
