Tribological properties on p91 alloy steel treated with normalizing & carburizing process

Abstract

An Experimental analysis was undertaken to analyze the changes in the Mechanical Properties and Microstructure of P91 steel, subjected to Normalizing and Carburizing heat treatment Processes keeping in mind the potential capabilities of P91 steel as the base metal due to its wide applications in Boilers manufacturing. P91 is a type of alloy steels having high hardness and wear resistance suface. The heat treatment processes were carried out in the present experimental procedure at constant temperature and for different timings like 60 minutes, 90 minutes and 120 minutes. Hardness of the specimen was tested by using Rockwell Hardness test. A pin on disc machine was used to conduct the wear test. Wear test was carried out on treated P91 steel on various parameters like variable load and constant speed. The Microstructural results are concluded with SEM (Scanning Electron Microscope) and XRD (X-Ray diffraction) techniques.
