Исследование физико-механических свойств твердых сплавов ВК6, ВК8 и Т5К10, прошедших объемное импульсное лазерное упрочнение

The results of studying the mechanical characteristics (microhardness, bending strength, abrasive wear resistance) and durability of VK6, VK8, T5K10 hard alloy specimens after volumetric pulse laser hardening (VPLH) are presented. It is shown, that x-ray diffraction analysis can be used for selection of optimal hardening modes (energy and duration of laser impulse, laser beam diameter, distance between irradiation point and major cutting edge), thus providing significant reduction of the material consumption, time and costs of laboratory testing. Methods of mathematical statistics are used for comparative analysis of the results and estimation of their reliability.
