Description

Effects of alloying powder coating thickness and continuous CO2 laser radiation power density on the steel structure homogeneity and surface strengthening in the process of laser boronizing have been investigated. The process technological parameters are found which provide the three types of borated layers occurring. Contribution of thermo-capillary and crystallization processes in laser chemical-heat treatment is discussed

Abstract (Russian)

Исследовано влияние толщины легирующих порошковых покрытий и плотности мощности излучения непрерывного CO2 лазера на степень структурной однородности и упрочнения поверхности стали, подвергнутой лазерному борированию. Определены технологические параметры процесса, обеспечивающие получение насыщенных бором слоев трех типов. Обсуждена роль термокапиллярных и кристаллизационных процессов в лазерной химико-термической обработке
