Investigation and analysis of a sustainable agro-based nanocoating on surface of metallic materials

In this study, nanotechnology was used to develop a coating from agricultural waste. Banana peels underwent various chemical processes, nanoparticles were developed and tests were conducted to validate it. The metal samples used for coating application were made of mild steel which is used to produce a large percentage of metal parts in the industry and was selected for this research project due to that reason. The metals were cut into 50 mm x 50 mm and 50 mm x 30 mm. The sample coatings included a control coating which was used as the yardstick to know the effects of the nano coating applied which contained various concentrations of nanoparticles showed results that were more favorable than the coatings that were applied without nanoparticles contained in them. Qualitative analysis of the coated metal samples A to G showed that sample E which had 7.24 grams of nanoparticles contained in it had the highest amount of hardness while sample A which was control coating possessed the least hardness amount. The abrasion test of the samples revealed that sample D which had 21.72 grams of nanoparticles contained in it possessed the highest weight of coating before and after the abrasion test.
