摘要

The effect of laser output power on the damage of TiO₂ ceramic coatings prepared by APS(Air Plasma Spray) under the condition of irradiation was studied. The mechanism of the coating damage was investigated. The results showed that: the TiO₂ coating damage became serious with the increase of the output power of the laser. When the power of the laser was 3900 W, the TiO₂ coating was destroyed. The thermal effect area was found in the matrix. The micro damage morphology of the TiO₂ coatings included mainly radiate structure and branch structure. The energy of lasers was depleted by the melting-recrystallization and propagation of the cracks in the Ti O₂ coatings.
