To analyze the feasibility about diffusion bonding of Ti-6Al-4V alloy (represented by TC4 below) and type 25 low carbon steel (represented by 25-steel below), two kinds of experiments have been conducted by Gleeble-1500. One is directly diffusion bonding research of TC4 and 25-steel, the other is diffusion bonding of TC4 and 25-steel with adding Ni intermediate layer. The surface microstructures and the phase composition of bonding Joint have been systematic analysis through scanning electron microscope (SEM), energy spectrometer and XRD. Results indicated that the Ni intermediate layer largely improve the strength of joints observably, by suppressing the harmful diffusion between two sorts of based metal to avoid the appearance of harmful intermetallics in the joints.

Using scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDX) we studied the distribution of structural parameters, phase composition and alloying elements concentration across the coatings obtained by cladding of chromium and titanium carbides mixture on low-carbon steel. The beam of relativistic energy electrons extracted into the atmosphere was used to form the coatings. The homogeneity in the allying elements distribution is shown to be defined by the lifetime of the melt bath while the phase composition distribution depends on the thickness of the melt layer. Both above parameters are determined by the density of the entered energy.
