Abstract
To further investigate the corrosion resistance of titanium matrix composites, this paper successfully established a columnar network distribution of 5 vol.% TiBw/TA15 composites using a low-energy ball milling and hot extrusion process. The electrochemical corrosion behavior of composites was studied and analyzed before and after the hot extrusion process in a simulated marine environment (3.5 wt.% NaCl solution). The result indicated that the corrosion resistance of the 5 vol.% TiBw/TA15 composites was enhanced after the hot extrusion process. This was because, during the hot extrusion process of 5 vol.% TiBw/TA15 composites, dynamic recrystallization occurred, leading to a more uniform distribution of alloying elements in composites after hot extrusion. This process mitigated the galvanic effect caused by the segregation of alloying elements, reduced the corrosion rate of the composite materials, and consequently enhanced their corrosion resistance.
