Исследование адгезии защитных композиционных покрытий на основе полифениленсульфида для теплоэнергетического оборудования

Composite coatings based on PPS for protection of water path and the elements of heat and power equipment were obtained. The estimation of adhesion by the cross-cut method was made. The substrate was made of steel 45 08H18N10 Steel, Cast Iron SCH21, Titanium W-1-0, magnesium alloy and brass AMg2 LAMsh. To prevent underfilm corrosion and to increase the level of adhesion to the base coating based on PPS all substrates were pre-treated with an organosilicon compound. Polymer matrix was filled by solid-state method with the hardening phase introduced by various scale polymer, metal, ceramic and silica-alumina powders. The coatings have a high level of adhesion to the metal base. Primers allow to solve the problem of underfilm corrosion.
