Abstract

Объектом исследования в работе были многослойные износостойкие наплавки из стали с мартенситно-аустенитной и перлито- ферритной структурами, полученные ручной дуговой наплавкой. Проводились исследования на микротвердость, износостойкость и твердость. Применялись методы микротвердости и оптической металлографии. Измерения износостойкости проводились на экспериментальной установке. На основании проведенных исследований изучена связь структурно-фазового состояния наплавок с микротвердостью, износостойкостью и твердостью. Проведенные исследования позволили сделать выводы об использовании и увеличении срока службы многослойных наплавок.

The object of the research was the multilayer deposition of wear resistant steel with a ferrite-perlite-austenite and martensite structures obtained by manual arc welding. Research was conducted on the hardness, micro-hardness and wear resistance. We used the methods of optical metallography and micro-hardness. Measurement of wear resistance was conducted using the experimental apparatus. On the basis of the research studied the connection of structural and phase state of built-up layers with a hardness, micro-hardness and wear resistance. The investigations led to the findings on the use and increasing of the life of the multilayer buildups.
