PURPOSE:To improve heat absorptivity and to make possible excellent laser beam processing by forming a coating layer contg. a laminar crystal lattice structure material on the surface of a work piece then processing the work piece. CONSTITUTION:The coating layer contg. 1 or >=2 kinds of so-called laminar crystal lattice structure materials such as fluorinated graphite, tungsten bisulfide, boron nitride and molybdenum bisulfide as the essential component is formed on the surface of the work piece and thereafter the work piece is processed. The need for a conventional preliminary operation such as blasting and chemical etching of the surface of a metal, etc. which required labor and time is thus eliminated and the heat absorptivity of the work piece surface is surely improved. |
