DESCRIPTION:Speakers: Christopher Mtshali (iThemba LABS)\nERDA and RBS ana
 lysis of hydrogenated Pd-Ti-Pd multilayer stacked film prepared on CT-Ti a
 nd Ti6Al4V substrates using an electron beam evaporator were conducted in 
 this investigation.  The hydrogenation of the samples was achieved by flow
 ing pure H2 (100%) and H2(15%)/Ar(85%) gas mixture while annealing samples
  at 550oC. The stability of the multilayer stack system at 550 °C was als
 o investigated using RBS for the investigation of possible intermixing of 
 layers and XRD for crystal structure and any possible new phase formation 
 due to elevated temperatures. SEM was used for surface topography investig
 ation. ERDA revealed an average H content of ~ 3.5 at.% in CP-Ti and ~6.2 
 at.% in Ti6Al4V for samples annealed under H2(15%)/Ar(85%) gas mixture. We
  recorded a hydrogen content of ~19.5 at.% in CP-Ti annealed under pure H2
  while ~25.5 at.% was found in Ti6Al4V annealed under the same conditions.
  Rutherford backscattering spectrometry (RBS) revealed intermixing of laye
 rs as evidenced by the diffusion of Pd toward the bulk\, while XRD indicat
 ed the formation of the PdTi2 phase in the samples annealed under vacuum a
 nd H/Ar gas mixture atmosphere. In-situ\, real-time RBS showed that the an
 nealing under pure H2 preserves the integrity of the Pd catalyst. No indic
 ation of the PdTi2 formation in the pure H2 annealed samples was observed\
 ; instead only the TiH2 phase appeared\, indicating the absorption of H in
 to the system. These results indicated the sensitivity of such a system to
  the H2(15%)/Ar(85%) gas mixture.\n\nhttps://events.saip.org.za/event/206/
