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

“…In [25,26] logarithmic, trigonometric, and logical functions were used also, as well as exponential functions to generate different kinds of fractals. In addition to that, it has been used of quadrilateral functions with the bi-compound in [16] as well as the tripartite complexes to generate fractals in [19].…”

“…In this work the Myrberg-Feigenbaum direction will be considered, the reason behind that is the existence of this kind of direction in both, one dimension and complex, quadratic maps, besides that the Mandelbrot set is a good reparative of the complex quadratic map. For the one-direction quadratic maps, the direction is simple and has a strong order known as the period-doubling cascade [19,20].…”

In this paper, the study of the dynamical behavior of logistic map has been disused with representing fractals graphics of map, the logistic map depends on two parameters and works in the complex plane, the map defined by f(z,α,β)=αz(1–z)β. where and are complex numbers, and β is a positive integers number, the visualization method used in this work to generate fractals of the map and to inspect the relation between the value of β and the shape of the map, this visualization analysis showed also that, as the value of β increasing, as the number of humps in the function also increasing, and it demonstrate that is true also for the function’s first iteration , f2(x0)=f(f(x0)) and the second iteration , f3(x0)=f(f2(x0)), beside that , the visualization technique showed that the number of humps in that fractal is less than the ones in the second iteration of the original function ,the study of the critical points and their properties of the logistic map also discussed it, whereas finding the fixed point led to find the critical point of the function f, in addition , it haven proven for the set of all pointsα∈C and β∈N, the iteration function f(f(z) has an attractive fixed points, and belongs to the region specified by the disc |1–β(α–1)|<1. Also, The discussion of the Mandelbrot set of the function defined by the f(f(z)) examined in complex plans using the path principle, such that the path of the critical point z=z0 is restricted, finally, it has proven that the Mandelbrot set f(z,α,β) contains all the attractive fixed points and all the complex numbers in which α≤(1/β+1) (1/β+1) and the region containing the attractive fixed points for f2(z,α,β) was identified
