Abstract

To analyze the interaction mechanism of Laser Water Jet (LWJ) with multilayer materials, an energy coupling model between LWJ and Thermal Barrier Coated (TBC) nickel-based alloy was established to examine the ablated morphology and temperature variation during processing. Building upon this foundation, vertical, inclined, and dustpan holes were precisely machined on the TBC alloy. The produced perforations exhibit impeccably smooth edges and planar surfaces, evincing a notable absence of a discernible heat-affected zone, recast layer, as well as any other thermal-induced detriments. Furthermore, through the utilization of the self-developed high-power LWJ machining equipment, the micro-hole fabrication in 6.1mm-thick DD10 alloy and 5mm-thick C/SiC composites have been achieved.
