激光微织构用吸光涂层正交工艺试验研究
Study on orthogonal processing experiment of light absorbing coatings for laser micro-dimple
摘要
Abstract
In order to improve the laser absorption rate of metal surface and processing surface quality of laser micro-dimple,W-71s type spray gun was used to spray black paint, water glass and yellow material on the surface of samples, respectively. Then, the samples were processed by Nd∶YAG laser. Compared with the uncoated specimens, the dimple volume increased and slag volume decreased respectively, around the dimples of specimen surface coated with water glass and yellow material. Dimple volume of the sample coated with yellow material increased by 29. 4%. On the basis, the influence of thickness and formula of water glass and yellow material on dimple volume and slag volume of laser processing surface were discussed by orthogonal experimental method. The results show that when the thickness of absorb light coating is about 0. 1mm, the content of yellow material is 17% and the content of water glass is 18%, the coating formulation is optimal. Compared with the uncoated sample, dimple volume of the best sample in orthogonal table increased by 70. 6% and the corresponding slag volume around the dimple decreased by 16. 2%. The study indicates that laser absorption rate and laser processing quality on the surface can be significantly improved.关键词
