J.E.I. Metallurgical, Inc. was asked to conduct laboratory testing on a sample of wire mesh that was implanted during a surgical procedure. An overall view of the wire mesh is shown in Photograph A.
Photograph A Failed wire mesh.
The area sampled by EDS is shown in Photograph B. The area in which chemical analysis was performed is denoted with a black inset box in Photograph B.
Photograph B Scanning Electron Micrograph (SEM) showing area in which chemical analysis was conducted.
The energy dispersive spectra obtained is shown in Energy Dispersive Spectra 1. As can be seen, the EDS spectra only indicates the presence of titanium (Ti). No spectra peaks were observed for nickel (Ni) or chromium (Cr) as would be seen if the mesh were fabricated from stainless steel. Thus, the chemical makeup was determined to be titanium (Ti) and not stainless steel.
