The Effect of a Scanning Nanosecond Laser Pulse Beam on the Microtopography of Ceramic Al2O3 Coatings

The ability to modify the surface microtopography of Al 2 O 3 ceramic using nanosecond laser pulses is elucidated via atomic force microscopy. The characteristic shapes and sizes of laser-modified surface microstructures are determined. The effect of absorbed energy density and laser radiation wavel...

Summary:The ability to modify the surface microtopography of Al 2 O 3 ceramic using nanosecond laser pulses is elucidated via atomic force microscopy. The characteristic shapes and sizes of laser-modified surface microstructures are determined. The effect of absorbed energy density and laser radiation wavelength on characteristic sizes of structures is shown as well.
