New Insights of Wear Behavior Analysis on Low Temperature Treated AISI 253MA Stainless steel Material by Gas Nitriding Process

Abstract

AISI 253MA Stainless steel samples were treat with the gas nitrating process at low heat around 450°C. It was seen that all-inclusive austenite stage exist when it is nitrade to 8 hours and post addition at time of nitrading to 16 hours the mix of ferrites and progressively substance of nitrogen was gathered in the following layers. Farther nitrading to 24 hour it has seen at Cr-N stage was discovered and turns the steel progressively firmer superficially. Erode tests were led by tribological wear testing machine to examine the tribological wear loss. Volume wear was found to be least in 18 hours test which demonstrated better improvement of wear improvement. High hardness were found in 24 hrs showing a hardness of 1080Hv. The sample nitrided to 24 hours exhibited better wear resistance, high hardness and low wear loss as well as low volume wear loss. Assessment examinations of nitrided test samples were investigated under scanning electron magnifying analysis.
