Investigation of Some Mechanical Properties of Cast Iron Coated with Chromium and Zirconia for Sliding Application
2021
In this project work, aluminium oxide/zirconia (30% Al2O3 + 70% ZrO2) and aluminium oxide/chromium (30% Al2O3 + 70%Cr) were coated through atmospheric plasma spray technique (APS) over cast iron as a base material, and some of its mechanical properties were studied experimentally. The hardness, wear and SEM and EDX of Al2O3/ZrO2, Al2O3/Cr coated and non-coated cast iron were taken, and the results were compared. Hardness, SEM and EDX results show that the chromium is better fused with cast iron than zirconium.
