Abstract

A composite material based on the Ni–Al–C system is synthesized by the method of an electrothermal explosion at a pressure of 96 MPa. During the electrothermal explosion in a reactive powder medium (Ni + Al + C), a Ni- and Al-based melt is formed, in which carbon dissolves. In the process of crystallization of the final product, carbon, due to its low solubility in NiAl, is located on the surface of intermetallic grains of NiAl in the form of multilayer graphite nanofilms 50–80 nm thick and fills the intergranular space. The microhardness of the synthesized material is 3084 MPa.

压力下电热爆炸合成具有多层碳纳米结构的Ni-Al-C复合材料

摘要

基于Ni–Al–C系统的复合材料是通过在96 MPa的压力下通过电热爆炸的方法合成的。在反应性粉末介质（Ni + Al + C）中进行电热爆炸期间，形成了Ni-Al基熔体，碳溶解在其中。在最终产品的结晶过程中，碳由于其在NiAl中的低溶解性，以50-80 nm厚的多层石墨纳米膜的形式位于NiAl的金属间晶粒表面上，并充满了晶间空间。合成材料的显微硬度为3084 MPa。
