Time-of-flight secondary ion mass spectrometry and X-ray photoelectron spectroscopy were used to study the influence of ageing 2024 aluminium alloy at 190 °C on subsequent degreasing deoxidation behaviour. After aged alloy, an increase in surface Cu coverage a roughening observed as compared non-aged alloy. The enrichment affected growth mechanisms trivalent chromium process (TCP) coating. TCP ...
Corrosion is an environmental evil related to metal and their alloys. Researchers trying best overcome it with traditional new techniques. Recently Conducting polymers (CPs) such as polyaniline (PANI), polypyrrole (PPy) etc. are used for the corrosion protection of metals Various mechanisms have been suggested explain anticorrosion properties CPs. These include anodic protection, controlled inh...
