Measurement of Residual Strain in Cold Spray Process Using X-Ray Diffraction and Finite Element Method
Cold spray technology has the potential to be utilised in broader industrial applications especially for oxygen-sensitive materials such as titanium. In this paper, the effect of titanium cold spray coating on residual strain after deposition is evaluated. Ring-shaped sample of 16.5 mm diameter was directly fabricated from titanium powder by cold spray. Using an X-ray diffractometer (XRD) and finite element analysis (FEA), the coating surface was analysed and compared. The XRD measurements revealed that residual strain at the sample surface (εXrD) was around 0.140. There was also some X-ray peak broadening of steel, which may be related to presence of porosity in unpolished samples. In addition, a good correlation was found (ε1EA≈0.169) when the residual strain results obtained from FEA were compared with the conducting test outcomes. Therefore, finite element method can be considered as a cost effective tool in quantification of strain in cold spray titanium structure.
