Enhancement of laser heating process by laser surface modification on Titanium alloy
Journal of Mechanical Engineering and Sciences, 2021 Titanium alloys are widely utilized in laser heating applications. However, it has poor optical properties due to low laser energy absorption. Nevertheless, a higher energy absorption can be realized by modifying the surface profile through increasing ...
