“…Furthermore, the optimization of the ingredient content in the polymer matrix was carried out to develop coatings with increased corrosion resistance and hydroabrasive wear resistance. Based on the mathematical planning of the experiment, four types of protective coatings (with different contents of the ingredients), which are characterized by maximum cohesive strength, were selected [16]. e corrosion resistance and hydroabrasive wear resistance of these materials were investigated.…”

“…e analysis of works [6][7][8][9][10][11][12][13][14][15][16][17][18] allows to state that epoxy composites are characterized by chemical stability and wear resistance in different operational conditions, wherein the adhesive strength of the polymers to the base and the cohesive strength of the material are main criteria that provide protective properties for a long time of operation. As it is known, acid solutions are the most aggressive medium for epoxy composites.…”

The corrosion resistance and hydroabrasive resistance of the developed epoxy composite coatings are investigated in this paper. The analysis of the penetration index change after τ = 50–150 days of immersion in a water medium and 10% sulfuric acid solution is carried out. The optimal ratio of the modifier and nanodispersed (Si3N4, Al2O3, AlN, and TiN) and fibrous (viscose, polyamide, matka silk, rong, and cashmere) fillers in the epoxy binder is determined. It was allowed to slow down the process of electrochemical reaction on the metal surface. The penetration of aggressive media in such a coating during the time t = 150 days is 0.8–2.8%. It is 1.5–2 times lower than the similar indexes of the initial epoxy matrix. The rational combination of the fibrous filler (wool, acrylic PAN, and cashmere), modifier, and nanodispersed (Si3N4, AlF3, IH, and ZrH) filler in the epoxy binder is found, which allows to provide optimum indexes of wear rate. The wear rate under the action of a hydroabrasive of such a coating is I = 0.20%, which is 4 times lower than the similar indexes of the initial epoxy matrix. The wear mechanism of such coatings is caused by the physical and mechanical processes of microcutting and plastic deformation of the surface layer of the material.

“…The authors [3][4][5][6][7][8][9] have shown that it is advisable to introduce fillers at a critical content in order to improve the properties of coatings, which are operated in the conditions of influence of corrosive environments and variable temperatures, in the complex. At the same time, it is important to choose the additives that should be active to the physical and chemical interaction with the polymer during the crosslinking.…”

It is proved that in order to increase the operational characteristics of parts of the river and sea transport, including their physical and mechanical properties, it is advisable to use the protective polymeric composite coatings. The effect of fillers on the flexural stresses of the developed epoxy composite was analyzed. The critical content of components was determined by the method of mathematical planning of the experiment: the synthesized powder mixture - 0.05 pts.wt., discrete fibers - 0.10 to 0.15 pts.wt. per 100 pts.wt. of epoxy oligomer ED-20. Introduction of such ingredients into the epoxy binder allows to increase the flexural stresses to σ f=77.4…78.6 MPa. The obtained results allow to create materials with improved values of physical and mechanical properties.

Epoxy diane oligomer ED-20, polyethylene polyamine PEPA hardener, powdered synthesized iron/titanium carbide mixture with dispersion of 10...12 μm, and the filler of plant origin with dispersion of 0.4...0.6 μm were used to form anticorrosive coatings. The investigation of the change in the value of resistivity and specific capacity in the diesel fuel environment was carried out, taking into account the rational ratio of differently dispersed fillers in the epoxy binder. The decrease in the resistivity of protective coatings by 1.5...1.6 times relative to the epoxy matrix was achieved. At the same time, the correlation with the value of the capacitance, which decreases by 1.8...2.0 times, respectively was established. Additionally, visual analysis of the surface of the developed coatings was carried out. They were kept for 6552 h in the river water at variable temperatures - T = 263...293 ± 2 K. For coatings containing the rational combination of two fillers, no defects in the form of cracks, peeling, and swelling were observed.
