Surface Modification of TiC–NiCrAl Hard Alloy by Pulsed Electron Beam

Abstract

The mechanisms by which nanostructural states are realized in e-beam-irradiated TiC-NiCrAl cermet depending on the irradiation mode have been revealed. Mechanical testing and tribotesting have yielded criteria for a substantial (a factor of 1.5-3) increase in performance characteristics of the cermet alloy (micro-and nanohardness, cutting resistance, coefficient of friction, and bending resistance).Index Terms-Hard alloy, microstructure, pulsed electron beam modification.

The Structural Transformations of Different Grades of Carbon Black Exposed to a Pulsed Electron Beam with a High Energy Density

“…In 2010, the IHPP, together with the IHCE, began research on the modification of CB. The IHCE has at its disposal unique electron beam units making it possible to study the possibilities of modifying different materials by means of intense pulsed electron beams of micro-and submillisecond duration in a wide range of variation in beam energy and current [4,5].…”
