The vacuum-arc plasma-assisted method was used to deposit a multilayer coating based on Ti and Al in two discharge systems - in a traditional plasma-assisted vacuum-arc spraying system and in a system for generating of gas-metal beam-plasma formation formed in a hollow cathode of a non-self-sustained low pressure glow discharge. The coatings obtained in the investigated discharge schemes are close in elemental and phase composition. In the coating deposited in the plasma-beam formation, the aluminum content is 8% lower, which is probably due to the overall higher average value of the ion flux density on the surface of the growing film in a non-self-sustained glow discharge. In the coating obtained by sputtering in a beam-plasma formation, there are no elements that are part of the material of the sputtered hollow cathode. Gas-metal beam-plasma formations, formed at low pressure, are promising in the processes of functional coatings deposition by the vacuum-arc plasma-assisted method.
В данной работе представлены физико-механические и триботехнические свойства однослойных и многослойных покрытий системы TiB/TiBN и TiBCr/TiBCrN. В результате анализа полученных данных было определено, что наибольшее значение микротвердости имеет однослойное покрытие с добавлением хрома TiBCrN. В результате проведения триботехнических испытаний максимальной износостойкостью и наименьшим коэффициентом трения обладают однослойные покрытия с хромом. При испытании фрезы с многослойным покрытием TiCrB/TiCrBN, время эксплуатации режущего инструмента увеличилось в 4 раза по сравнению с фрезой без покрытия.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
