Laser treatment
Asperity formation mechanism by laser treatment (Simulation)
The aluminum in the laser irradiation part melts and evaporates, and the melted aluminum accumulates around the depressed part.
Surface observation result of laser treated Al
Asperity of several tens of μm and fine asperity of nano-level are formed on the surface of the aluminum.
Cross-section observation result of laser treated Al
It can be seen that the fine asperity shape is formed as a film.
