О влиянии доли нитрида тантала в твердых сплавах Т12А и Т23А на эффективность получения наноструктур при действии фемтосекундного лазера

Abstract

Based on the theoretical study of the influence of the technological parameters of a femtosecond laser (heat flux density, irradiation time, contact spot radius) on the obtained volume of a nanoclusters (NC) for hard alloys T1 2A and T23A, the following conclusions are drawn: 1) with an increase in the density of heat flow, a decrease in the time of its action and the size of the spot radius, the volume of the ND, and consequently its dimensions, decrease; 2) we should expect an increase in physico-mechanical characteristics of the RI. The grain size in the T23A alloy is somewhat higher, which indicates the long-term use of T12A with nanostructures, which is confirmed by its greater hardness than in T23A, i.e. an increase in the proportion of tantalum nitride reduces the hardness of the nanostructure.
