It is often believed that pitting events are stochastic without any spatial or temporal effect on each other. However, as pits begin to form, the local environment changes [1]. Solution concentration and potential gradients develop that can affect pitting susceptibility on adjacent surfaces. These factors can also affect nearby oxide film and non-metallic inclusions to produce more permanent in...

Zinc plating is widely used to protect steels against corrosion. However, the possibility of a high environmental risk for zinc has been recently discussed among advanced countries and more environmentally-friendly substitutes are required urgently. Therefore, monitoring zinc concentration changes on metallic materials such as steel is very important. We chose to measure zinc concentration chan...

the aisi 316 l stainless steel (ss) specimens were exposed to passivation surface through two different processes including; holding in 40-vol% hno3 at temperature of 60 ºc for 30 min and 15-vol%h2so4 at ambient temperature for 1 hour. the corrosion behavior of specimens was evaluated in physiological solutions by electrochemical in vitro tests through linear and tafel polarization tests. cycli...

Electronic industry uses a number of metallic materials in various forms. Also new materials and technology are introduced all the time for increased performance. In recent years, corrosion of electronic systems has been a significant issue. Multiplicity of materials used is one reason limiting the corrosion reliability. However, the reduced spacing between components on a printed circuit board...

AISI 430 stainless steel is an attractive material to be used in the healthcare industry, particularly as a sensor due its low cost, corrosion resistance, well being Ni-free. was evaluated artificial sweat solution with presence of Escherichia coli, and Staphylococcus aureus. Surface microbial analyses did not reveal colonization bacteria on metallic surfaces, even when adhesion investigated Mü...

Electrical contacts, although critically important for a wide range of applications, are susceptible to degradation due fretting corrosion, especially when sliding and vibrations occur. To overcome corrosion wear, lubricants often used. However, the use can cause other detrimental issues. Lubricants usually consist non-conductive fluids such as hydrocarbons fluorocarbons. Due fluid dynamics, sl...

In this study, the bio-electrochemical response of the Ti–Zr–Si thin film metallic glasses (TFMGs) in simulated body fluid with different contents of titanium is measured via potentiostat. According to the results of bio-corrosion potential and current, as well as the polarization resistance, it is concluded that the Ti66Zr25Si9 TFMGs possess the highest bio-electrochemical resistance. With inc...

The integrity and safety of metallic structures can be jeopardized by structural damage (e.g., yielding, cracking, impact, corrosion) that can occur any time. While various sensors have been proposed and validated for structural health monitoring, most sensors only provide data at a discrete point on the structure. Here, a carbon nanotube-polyelectrolyte sensing skin is proposed for monitoring ...

Grace GmbH & Co. KG Cost reduction and health, safety, and environmental issues are primary drivers of change in the coatings industry today. The users of all kinds of metal products are not only concerned that the products they buy will be long-lasting and the costs of maintenance minimal, but also that the materials used are damaging neither to human health nor the environment. The coatings m...
