In order to discuss the influence of component of solution on generation of the treated layer by laser-induced wet treatment, the test pieces of SUS316L were soaked in several solutions, which had acidity or alkalinity, were irradiated by laser. The active solution; Al(NO3)3 and AlCl3 solution generated the treated layer of Fe2+Al2O4. The treated layer generated in Al(NO3)3 solution was thinker than that in AlCl3 solution. On the other hand, the treated layer generated in NaAlO2 solution, which was alkali, was composed of Fe2+Fe2O4. This implies that pH of the solution influenced on the generation of the treated layer.
