Abstract
The analysis of problems and results of researches in the field of non-isothermal sintering methods of the diamonds containing composites are presented in this paper. Results of experimental study of the influence of a laser irradiation on qualitative characteristics of diamonds, on physical and chemical processes on the diamond-sheaf border are submitted; the data indicating the existence of certain set of the regimes of laser irradiation that preserve the initial durability of diamonds, and some certain regimes that lead to the crack formation, oxidation and other negative processes are presented. Some problems of the development of the technology of coupled thermal and deformational laser sintering of composites, means of its realization, results of theoretical and experimental studying of the thermal processes that occur at liquid-phase sintering, basic technological parameters are discussed in detail. Results of practical realization of the developed process are shown.
Keywords: laser sintering, composites, diamonds, binders, tools, modeling, durability
