Представлено результати дослідження впливу зміни параметрів процесів лазерного та комбінованого лазерно-мікроплазмового легування на структуру поверхневих шарів та впливу структурних параметрів на зміну фізико-механічних властивостей одержаних легованих шарів. Використовуючи залежності металофізичних теорій управління структуроутворенням, виконано аналітичні оцінки характеристик тріщиностійкості, в’язкості руйнування та диференційованого внеску різних структурних факторів у зміну інтегрального значення границі текучості.
