This paper reports the first results of an ongoing
research work on rapid surface alloying of an AISI 316L stainless steel by
low energy, high current pulsed electron beam (LEHCPEB) with the aim of
enhancing the corrosion resistance of this material against aggressive
halide ions. A Ti powder layer was deposited on the substrate and
in-corporate at the top surface by using LEHCPEB. Due to the rapid surface
melting, liquid state mixing occurred and a Ti-rich layer formed. The
alloyed layer contained a mixture of the 
and γ phases
because the addition of Ti favors the formation of α. The corrosion
resistance of the AISI 316L stainless steel in the simulated body fluid was
effectively improved after surface alloying by Ti.
