Investigation of Wear Behavior of 34CrNiMo6 Low Alloy Steel Coated by PACVD Method
摘要
Despite favorable and various properties, low-alloy steels lack appropriate surface properties and strength. Accordingly, low-alloy steel 34CrNiMo6 was coated by the PACVD process. To this end, resources to supply titanium, nitrogen, and carbon were used in the coating composition. The methane flow rate is the main variable to create coatings with different compositions and thicknesses. The resulting coatings were studied and analyzed in terms of mechanical properties and microstructure by EDS, AFM, FESEM, GIXRD, and XPS. The results showed that the C3N4 phase formed with the formation of nitride and carbide compounds in the compositions improved the tribological properties of the coatings. Increasing the methane flow rate significantly affected the carbon content of the coatings.
