Enhancement of Tribological properties of Mild Steel using ZrO2 Nano Particles

  Mohd InayathUllah,  Dr. B. Nageswara Rao,  D.Santhosh

Now-a-days, steel has become an important part of our life due to its extensive applications in automotive, household appliances, business machine and heavy construction such as marine and chemical industries. Mild steel is selected for construction because of its mechanical properties and machine-ability at a low price, while at the same time; they have to be resisted against corrosion phenomena. For this study, ZrO2 nano particles were synthesized by solution combustion process and size was found to be 45 nm from X-ray diffraction. Plate sample (10x10x3 mm) of mild steel was used as a substrate and after Polishing to about Ra 20 µm using Al2O3 slurry; the samples were first cleaned with acetone and then ultrasonically cleaned in ethanol, then heat-treated at different temperatures like 400˚C and 500˚C in a muffle furnace. After heat treatment the samples are coated by applying ZrO2 nano particles with an airbrush device. Coated samples are tested for surface roughness, X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM).
