The YAG laser texturing technology and application with controllable disorder distribution

Abstract-The special morphology of spots isolated from each other could lead the laser texturing (LT) sheet to better stamping and coating properties, compared with shot Blast texturing (SBT) sheet and Electro-discharge Texturing (EDT) sheet. While the spots with regular distribution caused the laser texturing sheet appearing fringes easily. There were three methods to achieve YAG laser texturing disorder distribution spots, including controlling disorder delay, controlling disorder deflection, and controlling disorder image carving, which could reach the disorder spots texturing effect of EDT, and resolve the fringes problem of laser texturing. JM-3000 YAG laser texturing equipment was composed by mechanical system, laser system, controlling system, the outside optical system, frequency convertion cooling system and protection gas system, which achieved the disorder spots distribution of YAG laser texturing.
