Waware, Umesh Somaji; Arukula, Ravi; Hamouda, A. M.S.; Rashid, Mohd ( Springer Science and Business Media Deutschland GmbH , 2022 , Article)In the present work, we prepared enormously soluble poly (aniline-co-3-aminophenol) (PA-co-3-AP) copolymers via a simple chemical oxidative method with aniline and 3-aminophenol, and their properties are compared with ... -
Dry sliding tribological properties of a hard anodized aa6082 aluminum alloy
Santecchia, E.; Cabibbo, M.; Hamouda, A.M.S.; Musharavati, F.; Popelka, A.; Spigarelli, S.... more authors ... less authors ( MDPI AG , 2020 , Article)The applications of aluminum and its alloys are still limited by low hardness and low wear resistance properties. Surface modifications, such anodizing and plasma electrolytic oxidation, represent a feasible way to overcome ... -
Effect of addition of Pd on electrodeposited Ni–B coatings
Waware, Umesh Somaji; Nazir, Roshan; Hamouda, A. M.S.; Pradhan, Ajaya Kumar ( Springer Science and Business Media Deutschland GmbH , 2022 , Article)In this study, the effect of addition of a noble metal (Pd) to the Ni–B nano-coating is studied. The Ni–B and Ni–B–Pd coatings are synthesized from aqueous electrolytes using direct current. The Ni–B coating is found to ... -
Electrochemical and X-ray photoelectron spectroscopic investigations of conductive polymers
Waware, Umesh Somaji; Arukula, Ravi; Hamouda, A.
