The experimental results indicated that under the protection ofAr gas, buckytubes could retain their straight vacant form or curl to form bound buckytubesand even decompose to produce Fe3C with Fe under the laser irradiation. Furthermore, an alloyed layer, which contents 2.5%-3.5% carbon, could be formed on the carbon steel surface.The hardness of the carbon steel surface could be up to HRC 70 when the sample wasquenched after austenitized at 840 ℃ for 10-20 min. And the wear resistance of the treatedsurface was increased efficiently.
