“…Figure 7 shows the graph of the taper variation of laser-ablated dot texture with the number of ablations in the liquid-phase environment, and it can be seen that the taper shows a decreasing, then increasing, and then decreasing trend with the increase of the number of ablations. The taper trend is divided into three stages [31]: The first stage is unstable because the initial ablation number is small (1~2), and the change in diameter difference between the top and bottom of the dot texture will increase, while the depth change is small, and the taper fluctuation range is large. The second stage is the stabilization stage when the number of ablations is 3-4, the ablation rate is accelerated, the diameter and depth of the pit top and bottom increase simultaneously, and the calculated value is smaller according to the taper equation.…”

To explore the influence of the number of laser ablations on the shape, geometry, and taper of the pitting structure by laser ablation in the liquid phase, three-dimensional confocal microscopy was used to quantitatively characterize the shape of the surface dotting texture of YG8 cemented carbide and analyze the evolution of the morphology based on the liquid-assisted laser ablation test. The results show that the surface pitting structure of YG8 cemented carbide evolves from a micro-convexity to a crater with the increase in the number of laser ablations, and the bottom of the crater produces a convexity after 7 ablations, the shape of the crater evolves to a trapezoidal shape after 13 ablations, and the shape is stable. The size of the dot texture increases with the number of laser ablations and reaches a maximum value of 396 μm in diameter and 149 μm in depth at the 10th and 12th ablations, respectively. The taper of the dot texture showed a trend of decreasing, increasing, and then decreasing with the increase in the number of laser ablations, and the taper was stable with more than seven ablations. This study lays a theoretical foundation for the control of the dot texture morphology on the surface of YG8 cemented carbide by laser ablation in a liquid-phase environment.
