10/12/2021 The effects of Mg and Al content on the microstructure and corrosion resistance of hot-dip Zn-Mg-Al alloycoated steel sheets were investigated. Pure Zn and Zn-based alloy coatings containing Mg (0-5 wt%) and Al (0.2-55 wt%) were produced by a hot-dip galvanizing method. Mg and Al addition induced formation of intermetallic microstructures, like primary Zn, Zn/MgZn2 binary eutectic, dendric
In this study, we investigated the galvanic corrosion performance of an Aluminumndash;Boron Nitride (Alndash;BN) abradable seal coating system (with a Ni5Al bond layer and a 0Cr17Ni4Cu4Nb substrate) in chloride solution by electrochemical methods. The results indicated a three-stage process occurred during the anodic dissolution of the coupled coating system, consisting of a spontaneous
5/2/2021 Chloride ions then react with the oxide film causing a local breakdown – a pit, hence the name pitting corrosion – within it. Corrosion is an electrochemical process leads to surface wastage of metals. In order for corrosion to occur, four basic elements are required: 1. Anode – site where corrosion occurs and from which current

Chloride stress corrosion cracking (CLSCC) is one of the most common reasons why austenitic stainless steel pipework and vessels deteriorate in the chemical processing and petrochemical industries. The objectives of this work were: To draw conclusions

Chloride stress corrosion is a type of intergranular corrosion and occurs in austenitic stainless steel under tensile stress in the presence of oxygen, chloride ions, and high temperature. It is thought to start with chromium carbide deposits along grain boundaries that leave the metal open to
Aluminum is highly resistant to the effects of concrete and cement mortar, despite their high alkalinity with a pH value of about 12. When the concrete starts to set, always occur slight aluminum etching depth of not more 30 m. This impact, However, slows down after a few days of contact (figure
