Abstract

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.

高压塑性变形后铁与聚合物和低分子量有机化合物的混合物中的热过程

摘要

已经研究了通过“铁粉-聚合物”混合物的强烈塑性变形制备的金属-聚合物复合材料的各种聚合物基质的钝化性能，以及在填料（活性铁颗粒）存在下它们的热分解过程。以及随后的铁钝化和氧化过程。为此，首先将铁与各种成分的10 wt％的混合物在Bridgman铁砧上分别在1.5和2.5 GPA的压力下进行塑性变形，然后在20-800°C的空气温度范围内通过热重法进行研究。中。在量热计中将变形的混合物在30-400°C的T范围内加热时，已记录了与有机化合物分解相关的重量损失，而在400-800°C的T范围内，这是与铁氧化有关的重量增加。在两个T范围内的体重变化都伴随着放热效应。
