Аннотация:The passivating properties of various polymer matrices have been studied for a metal-polymer composite prepared by intensive plastic deformation of “iron powder–polymer” mixtures, as well as the processes of their thermal decomposition in the presence of a filler (active iron particles) and processes of subsequent iron depassivation and oxidation. For this purpose, the initial mixtures of iron with 10 wt % of various components underwent plastic deformation under pressures of 1.5 and 2.5 GPA on Bridgman anvils and then were investigated by the thermogravimetric method in the temperature range of 20–800°C in the air medium. Upon heating the deformed mixtures in a calorimeter in the T-range of 30–400°C, a weight loss associated with the decomposition of organic compounds has been recorded, whereas in the T-range 400–800°C—it was a weight gain associated with iron oxidation. The weight changes in both T-ranges were accompanied by exothermic effects.
