摘要

Electron beam surfi-sculpt could modify the surface structure; Which would be potentially used in the area of materials surface treatment. In this paper; electron beam surfi-sculpt of Ti-6Al-4V was realized by a new control system and a innovative hexagon scanning waveform. At the same time; microstructure and hardness of protrusions was analyzed. It was found that four different structural zones existed in the protrusion; including base metal; heat affected zone (HAZ); central zone and edge zone. The hardness result showed that the value of HAZ was the biggest; while the rest were similar. Finally; forming mechanism of surfi-sculpt was investigated by numerical simulation. The results showed that surface tension and metal vapour pressure were key factores of developing of protrusions.
