Epoxy/alumina composite coating on welded steel 316L with excellent wear and anticorrosion properties

Abstract

The main purpose of this study is to elaborate anticorrosive coatings for the welded steel 316L, since this later is widely used in industrial field. Hence, within this work we have studied the electrochemical behaviour of different zones of the welded steel 316 in 1 M HCl media. The macrography study of the welded steel has revealed the different areas with a good contrast. We have stated three different zones, namely; melted zone (MZ), heat affected zone (HAZ) and base metal zone (BM). Impedance studies on welded steel 316L were conducted in 1 M HCl solution, coating of Epoxy/Alumina composite was applied on different zones, in order to reveal the anti-corrosion efficiency in each zone. Scanning electron microscopy (SEM) analysis was undertaken in order to check how far the used coating in such aggressive media protects the studied zones and these findings were assessed by water contact angle measurements. The choice of this coating is based on the cost and the safety. We concluded that the Epoxy/Alumina composite has a good protecting effect regarding welded steel in aggressive media.

Metoga GTAW Welding Joint Strength Study For Aisi 1045 Application Of Milling Tools

“…From the tensile test results, only samples that break off in the base metal area will be examined and tested. Three regions have an impact on the results of the welding, namely: the weld metal area, HAZ, and base metal area (Hammi et al, 2021). and then to be observed and analyzed as a recommendation for welding on materials with high strength or combining materials with different types.…”

Synthesis of TiO2 nanogel composite for highly efficient self-healing epoxy coating

“…Corrosion cannot be completely eliminated; hence, corrosion control methods have been focused on reducing its rate or changing the corrosion mechanism. These methods include cathodic protection, protective coatings, using corrosion inhibitors, or a combination of the aforementioned methods [4] , [5] , [6] , [7] .…”
