Abstract: In order to improve machining efficiency and the surface quality of laser surface texturing for metal surface, the W-71s type spray gun was used to spray black paint, water glass, yellow material, zinc phosphate and graphite on the surface of GCr15 bearing steels respectively. Then, the samples were processed by Nd:YAG laser. Finally, the morphology of material was measured by 3-D morphology analyzer. The experimental results show that compared with uncoated specimens, the removing volume and slag volume around the dimple of specimen surface coated with water glass and yellow material increase and decrease respectively. The removing volume of the sample coated with yellow material increases by 29.4% and the slag volume of specimen surface coated with water glass decreases by 64.9%. Compared with single coating, some composite coating has better laser surface texturing performance. The composite coating with water glass and yellow material has great laser surface texturing performance. Compared with uncoated specimens, the removing volume increases by 47.1%, the slag volume decreases by 43.2%. The result is very instructive to improve the machining efficiency and surface quality of laser surface texturing.
