A simultaneous in situ optical microscopy and simultaneous electrochemical analysis method is presented for studying 316L stainless steel in hydrometallurgical process solutions. The electrochemical method involved potentiodynamic analysis of the 316L stainless steel surface in aerated and deaerated experimental hydrometallurgy process fluids. This technique is reviewed along with other potentiodynamic methods used Read More

The development of hybrid materials is desirable given that combinations of polymers and inorganic materials can be self-assembled forming pre-ordered complex structures with precise mechanical, chemical and electrical programmable properties. These new materials possess new and/or enhanced properties. For instance, polymeric materials are widely used in industry because of their superior properties such as flexibility Read More

Elaborations in the field of chemical and abrasion resistant coatings and composite polymer materials by company Polymate LTD.-INRC (Israel) and its employees are reviewed. The main fields of advanced corrosion resistance materials are liquid and water based rubber compositions, hybrid nonisocyanate polyurethane coatings, nanostructured organic-mineral coatings. The review includes patents used by the industry of sev Read More

The discovery of the first petroleum off-shore fields 30 meters below sea level in the Brazilian coast in 1968 stimulated the development of new technology for oil extraction and production in increasing water deepness. Outstanding levels such as 6000 meters were expected for oil extraction in the offshore pre-salt reservoirs in the 2010s, which demanded a large amount of material, raising costs to extremely high levels. So, c Read More

This article deals with the effective attributes of friction material application out of aluminum matrix composites (AMC) containing disperse ceramic phase, particularly SiC particles, via literature survey and result analyzing of the relevant research works. These properties include thermal expansion coefficient, wear, friction coefficient, mechanical and thermal strength, durability, etc. The wear mechanism of braking in bra Read More

The poor corrosion resistance of magnesium alloys is limiting their widespread applications. Some patents and literatures have reported corrosion-resistant magnesium alloys and surface treatment techniques to improve the corrosion resistance. However, these acknowledges are not enough for well understanding the corrosion behavior of magnesium alloys in actual application environments. In this paper, the influence of Cl- Read More

The phenomenon of corrosion of metals including Fe, Al, Cu, Zn, Mg and their alloys is controlled to a great extent by selection of highly corrosion resistant inhibitors. The associated cost factor favors the use of cheap metallic materials along with efficient corrosion prevention methods in many industrial applications. In this aspect, corrosion inhibitors have a significant role in the protection of metals from corrosion. These inhibit Read More
