A niobium modified layer on a pure titanium surface was obtained by means of a double-glow plasma surface alloying technique. Microstructure and phases resident in the alloy layer were analyzed. The processing parameters and effects of cathode sputtering before the diffusion process were also studied. The results show that the surface niobium content in the modified layer is similar to that in the...
Surface age-hardening high-speed steel has been formed on the surface of different substrates by double glow plasma surface alloying (DGPSA) technique, which possesses many excellent properties such as high hardness, high anti-temper stability, high wear resistance, etc. The hardness of the surface alloying layer is mainly determined by the construction of alloying layer as thickness, element distribution,...
