The cooling rates also afforded by high power lasers [9,10] in local areas are certainly in the bounds of the quench rates necessary for “amorphisation”, and hence surface engineering by high power laser provides the chosen tool for this investigation into the formation of amorphous surface layers.
The phases of all samples were identified by X-ray diffraction (XRD) with a Bruker D8 Advance equipment using Co Kλ radiation (λ=0.1790 nm).
