Technological and scientific aspects of consolidation of refractory composites

Abstract

The monograph deals with modern methods for consolidation of powder mixtures based on refractory carbides, oxides and nitrides. Special attention is given to problems of compaction and consolidation of nanopowder mixtures based on refractory compounds. The monograph also presents the comparative characteristics of consolidation conducted with different methods, including the authors’ techniques for highly effective electroconsolidation, which, despite its similarity to the technological SPS-process, has some distinguishing characteristics that simplify the production process, decrease the cost and guarantee lower initial cost of the finished goods. It also describes the comparative operational properties of the different materials obtained and used for wear resistant and abrasive tools and nozzles.
