en Synthesis and Characterizations of Ni-W alloy سایر موضوعات Other subjects Research Paper Research Paper The Nickel tungsten (Ni-W) alloy was electrodeposited on stainless steel (SS) substrate using potentiostatic mode at room temperature. Potentiostatic electrodeposition was carried out by varying the deposition time. The physicochemical properties of Ni-W alloys were studied using X-Ray diffraction (XRD), Electron Microscopy and micro-Raman spectroscopy. Recorded XRD spectra was compared with standard JCPDS card and the presence of Ni was confirmed, no such peaks for W were observed. Further study was extended for micro-Raman analysis. From Raman spectroscopy study the appearance of Ni-O and W6+=O bonds confirms that the Ni-W present in amorphous phase. Several cracks were observed in SEM images along with nanoparticles distributed over the electrode surface. The appearance of cracks may be correlated with the in-plane tensile stresses, lattice strains and stacking faults and may be related to the substrate confinements.   Ni-W,Alloy,Electrodeposition,Amorphous,Raman Spectroscopy. 51 55 http://ijmse.iust.ac.ir/browse.php?a_code=A-10-5274-2&slc_lang=en&sid=1 Dipali Potdar dipalipotdar3@gmail.com 1800319475328460018425 1800319475328460018425 No Jaysingpur College, jaysingpur Sushant Patil sushant8385@gmail.com 1800319475328460018426 1800319475328460018426 No Shivaji University, Kolhapur Yugen Kulkarni yugenkulkarni@gmail.com 1800319475328460018427 1800319475328460018427 No Willingdon college, Sangli Niketa Pawar niketapawar2016@gmail.com 1800319475328460018428 1800319475328460018428 No Willingdon College, Sangli Shivaji Sadale shivajisadale@yahoo.com 1800319475328460018429 1800319475328460018429 No Shivaji University, Kolhapur PRASHANT CHIKODE prashantchikode@gmail.com 1800319475328460018430 1800319475328460018430 Yes Jaysingpur College, Jaysingpur
