Abstract
In recent years, hybrid organic-inorganic (HOI) materials have attracted massive attention as they combine the unique properties of organic and inorganic compounds. In this review, we focus on the formation of HOI materials and their electrochemical performance that can be controlled by microstructural design depending upon their chemical composition. This overview outlines the recent strategies of preparing HOI materials on metallic surface via wet-electrochemical systems, such as plasma electrolysis (PE) and dip chemical coating (DCC). The corresponding electrochemical behavior for short and long term exposures is also summarized.

Summary
The increasing demand for light metallic materials for use in cutting-edge applications of corrosion protection, catalytic activity, and bio-related performance has stimulated comprehensive studies among researchers around the world [1]. To improve the performance of light metals (Mg, Al, Ti, etc.) and their alloys, wet surface treatments, including chemical conversion, anodizing, and plasma electrolysis (PE) have been employed to deposit a protective layer on the metallic surface [1,2,3,4,5]. Among these strategies, PE ( denoted as micro-arc oxidation) is able to reform the surface of Mg, Al, Ti under high electrical polarization by utilizing myriads of plasma discharges accompanying the formation of an inorganic layer (IL) [1,4]. We provide a comparative summary on the electrochemical properties (e.g., icorr, Ecorr, corrosion rate) of various HOI materials fabricated via PE-DCC reported earlier
