Comparative Study of Structural and Mechanical Properties of as Deposited and Shock Wave Exposed NiW Nano Structured Thin Films

The current work describes the effect of shock wave exposure on electroplated NiW thin films. films were deposited through electrodeposition process by varying bath temperatures (35°C and 70°C) at constant density 1A/dm2. exposed to waves with Mach numbers 1.13 2.33 using an in-house tube facility. as-deposited wave-exposed characterized XRD, FESEM, EDS, EIS reveal its structural mechanical properties. XRD results disclose stable cubic phase as average crystallite size between 5 nm 17nm. elemental composition shock-wave are similar confirmed in EDS analysis. This henceforth represents stability nanostructured film terms compositional aspect. Morphological analysis FESEM shows that is defect free due impact waves. Furthermore, corrosion resistance observed enhance ten times than for higher mach number (Pressure ~63 bar). Similarly, low (pressure ~13 bar) increases three according Therefore, structural, morphological properties enhanced upon surface treatment exposure. such rate, high used various industrial applications like defense applications, aircraft, marine applications.
