Исследование влияния холодной пластической деформации на процесс диффузионного насыщения одновременно углеродом и бором низкоуглеродистых и борсодержащих сплавов

Abstract

Работа посвящена изучению влияния предварительной холодной пластической деформации со степенью деформации 0…40 % на процесс диффузионного насыщения бором и углеродом низкоуглеродистых и борсодержащих сплавов на железной основе. Установлено, что предварительная холодная пластическая деформация низкоуглеродистого сплава со степенью деформации 20 % при температуре 750 °С способствует увеличению глубины диффузионной зоны на 25 % и увеличению микротвердости перлитного слоя на 20 %.

This work is devoted to the study of influence of cold prestrain with degree of deformation within the range 0…40 % on diffusion saturation with boron and carbon for low-carbon and boron steels. It is determined that the plastic prestrain with degree of deformation 20 % at temperature 750 °С for the low-carbon steel promote increasing of boron-cementation layer thickness by 25 % and microhardness of perlite layer by 20 %.
