Abstract:

Sol gel technique is used in the preparation of titanium dioxide nanoparticles. 10ml of TTIP (Titanium tetra iso-propoxide) is mixed with 4.ml Isopropyl alcohol and further vaccinated at 450oC for 3 hours. Various techniques are employed to determine the crystalline phase, Fourier Transform Infrared Spectroscopy (FTIR) for the identification of functional group, Scanning Electron Micoscopy (SEM) for the partial size and surface morphology identification, Raman analysis to identify the polymorphism and local crystallinity. The other properties like optical properties of titanium dioxide nanoparticles are determined by Ultraviolet (UV) analysis. TGA (Thermo gravimetric analysis) to determine the thermal properties of titanium dioxide nanoparticles.

Abstract:

Frictions stir welding having the power to be used as various packages. But, It is very compulsory to conquer little demanding situations for its more-unfold utilization. Device physical appearance and choice of the methods parameters are vital troubles in the utilization of this method. Three specific device pin geometries (cylindrical threaded, Conical Threaded, MX-Trivex) and two distinctive manner changebles, i.e. rotational speeds and welding speeds had been decided on for the extended research. The welded specimens had been experimented for mechanical characteristics. It became located that rectangular pin profile gave better weld fine than the opposite profiles.
