Increase of Wear and Heat Resistance of the AISI 304 Steel Surface Layer by Multi-Pass Nanostructuring Burnishing
Journal Title: Journal of Materials and Engineering - Year 2023, Vol 1, Issue 2
Abstract
The paper presents the results of experimental studies of the AISI 304 steel disc surface after finishing turning, electropolishing and nanostructuring burnishing after one and five passes of the tool with a natural diamond tip with a radius of 2 mm. It is shown that surface layer nanocrystallization provides for almost complete decomposition of austenite in a layer up to 100 µm thick, an increase in microhardness up to 400...450 HV0.025 and a 3.3-fold reduction in the wear intensity on hardened AISI 1045 steel under conditions of lubrication with industrial oil compared with electropolishing. The content of residual austenite in the surface layer is not more than 5% when the temperature rises to 400°C.
