Abstract

In this paper, we study the features of structure formation in composite materials based on polytetrafluoroethylene containing from 50 to 90 vol % of nickel that results from the explosive pressing of powder mixtures in a cylindrical ampoule. It is revealed that, at an increase in parameters of explosive pressing, a change in the structure along the pressing radius that characterized by increased deformation of the components up to their grinding and remelting in the center of the pressing with a simultaneous increase in the physicochemical interaction of the components of the composite mixture is observed.

粉末爆炸压制镍-聚四氟乙烯复合材料的结构

摘要

在本文中，我们研究了基于50％至90％镍的聚四氟乙烯的复合材料中结构形成的特征，这是粉末状混合物在圆柱状安瓿瓶中的爆炸压制所​​致。结果表明，随着爆炸压制参数的增加，沿压制半径的结构发生变化，其特征在于，直到在压制中心进行磨削和重熔的部件变形增加，同时物理化学成分也增加。观察到复合混合物的组分之间的相互作用。
