ABSTRACT:
In this project we have found that the XRD pattern of the TiO2 nano particles, the peaks are observed at corresponding values. The SEM images of TiO2 nano particles shows respectable morphology and Grain size of TiO2 nano particles were nearly 60.03 nm. The Energy dispersive X-ray spectroscopy reveals that the required phase has present. Titanium and oxygen (O) Elements are present in the sample. The grain structure and size were nearly 240 nm. TiO2 Coated nano particles on mild steel at 500° C, shows respectable morphology when compared with base metal of the sample and grain size of coated sample 500° C were nearly 204 nm. Initially the surface roughness of the base metal is high when compared with heat treated sample at 500°C due to the heat treatment the surface roughness of the sample is smooth. Surface roughness is high after deposition of Tio2 nano particles on mild steel at 500°C, due to high bond generated between Tio2 and mild steel during dipping process.
KEYWORDS: TiO2 nano particles, mild steel, XRD and SEM analysis.
1.INTRODUCTION:
Nanotechnology literally means any technology on a nanoscale that has applications in the real world. The nanotechnology in mechanical engineering and manufacturing is immensely useful to the field. Nanotechnology can be used to increasing the life of the components and automobile parts. A many number of materials can be enhanced by the use of nanotechnology. In this paper they focused on deposition of Al2O3 nano particles on steel by machining process and heat treatment process. A considerable difference in hardness is achieved after deposition. Surface roughness is lowered after deposition. Xinkun Suoa et al stated that microstructure, phase structure, oxygen content and micro hardness of the coating prepared under different main gas temperatures were investigated. The critical velocity of the particle was evaluated through numerical simulations [1]. M.Sneha-P. Sammaiah et al stated that The particle deformation behaviour and bonding mechanism were discussed. The result of the oxygen content test showed that the oxygen contents of the coatings did not increase comparing with that of the feedstock powder. The simulation results revealed that the critical velocity of Mg particles was in a range of 653 m/s to 677m/s [2]. The paper investigated on microstructure evolution as...
