In this study, nanosecond-pulse laser is used in combination with cold spraying to form a hybrid solid-state forming technology: nanosecond-pulse laser assisted cold spraying. This method successfully manufactured Al-Cu high-strength aluminum alloy coatings. The nanosecond-pulse laser reduced the porosity of the coatings. The laser-induced micro-texture on the substrate surface had the ability of improving the bonding strength of the coating-substrate interface. The bonding strength was closely related to the depth of the micro-texture. The deeper micro-texture caused an unfused interface on the bottom of the texture, which produced voids and reduced the bonding strength. The nanosecond-pulse lasers can also increase the hardness of the coatings. The assistance of the nanosecond-pulse laser has proved to be an effective method to improve the quality of cold sprayed metal coatings.

In this paper, a hybrid quasi-micro-pyramid structure is fabricated via nanosecond pulse laser micro-processing, which demonstrates a 15% drop in average reflectance as compared to the uniform quasi-micro-pyramid structures. The influences of laser fluence, pulse number, and designed pitch are also studied experimentally and systematically. The results show that reflection increases with the pattern pitch, decreases with pulse number, and a minimum in reflection is reached at a laser fluence of 4.83 J/cm2. The method here demonstrated provides an alternative and low-cost solution for broadband anti-reflection by hybrid structures with normal aspect ratio rather than uniform structures with high aspect ratio. Higher antireflection performance can be expected by optimizing the laser processing parameters.
