Experimental study with analysis for a novel saturated activated alumina photovoltaic thermal system

Aluminum Oxide Ceramic Coatings on 316l Austenitic Steel Obtained by Plasma Electrolysis Oxidation Using a Pulsed Unipolar Power Supply

“…A known solution is to prepare alumina ceramic coatings on the surface of stainless steel [11][12][13].Alumina is one of the important technical ceramics due to its useful properties (i.e., hardness, thermal, chemical, and dielectric) [14][15][16]. Alumina films have received considerable attention as high temperature engineering material [17]. There is an increasing technological need to protect metals in aggressive environments such as acidic or oxidizing environments [18].…”
