“…The paper [22] presents the results of research on the effect of catholyte on the kinetics of corrosion was studied and revealed the dependence of the corrosion rate of carbon steel 09G2S on the concentration of the reagent alkali and catholyte at different pH values where a comparative assessment of the use of the most effective concentration of catholyte to increase the corrosion resistance of the material has been carried out. The paper [23] presents the results of research on the preparation of metal matrix nanocomposites using Fe as base material reinforced with Al 2 O 3 and doped with CeO 2 using the powder metallurgy technique. It was observed that corrosion rate and corrosion current density was highest for pure Fe samples whereas 1.0 % CeO 2 doped Fe-Al 2 O 3 metal matrix nanocomposite system showed the formation of nano amorphous layer on the specimen surface.…”

This work aims to the identify level of hybrid nanocomposite coatings of a stainless steel alloy that is used in the manufacture of mineral reservoirs for the storage of oil products in the oil products distribution company (Opdc). Corrosion is one of modern society's most serious engineering problems where losses incurred due to it each year are estimated at billions of dollars. Technological options have to be exercised to protect against corrosion and an effort to combat these losses. To overcome this severe problem, several successful efforts have been made using corrosion inhibitors. Corrosion inhibitors are compounds used in low concentrations to prevent or slow down the corrosion process. The used metal (low carbon steel St-37) was coated with zinc phosphate as an initial layer, cellulose nitrate reinforced with MgO nanopowder by weight percentage (3 wt. %) as an intermediate layer, and epoxy resin reinforced with weight reinforcement percentage (2 wt. %) of particles (MgO+coke coal (1:1)) as a final layer. In addition, a cognitive scale was prepared from (hardness, adhesion strength, chemical corrosion test as well as electrochemical corrosion test. It was found the hardness increased with coated by an initial layer and the value of adhesion strength of triple coating layers was (232 Psi). Chemical and electrochemical corrosion tests have shown the efficiency of prepared coating layers in corrosion inhibiting and metal protection. The used inhibitors in the work are inexpensive materials that allow solving the problem of rational nature management by reducing corrosion and providing the transition to the use of environmentally safe efficient technologies
