Alloying of Pd into Ti by pulsed plasma beams

Pd¯Ti alloy surface layers in Ti formed by N- and Ar-pulse plasma alloying of Pd films deposited by pulse erosion of Pd electrode tips were studied by RBS, XRD, SIMS, and gravimetric analysis. Layers of a thickness up to 2 m and concentration up to 40% Pd at the surface were obtained. Pd is present as a solute in hcp Ti and as TiPd and TiPd3 phases. The Pd profiles follow Gaussian distribution although no simple theoretical model can account for this behavior.
