What's Happening?
Recent advancements in waterjet-assisted laser micromachining (WJALM) have significantly improved the precision and quality of large aspect ratio (LAR) microgrooves in silicon carbide (SiC) ceramics. This technique involves a strategic angle between the waterjet and laser beam, where the water layer formed by the laser passing through the waterjet aids in material removal and cooling. The process effectively reduces thermal effects and recast layers, crucial for applications in fuel injection nozzles, heat exchangers, and semiconductor packaging. Comparative studies show that WJALM produces microgrooves with minimal thermal distortion and better geometric control compared to underwater laser micromachining (UWLM). The method's ability to prevent microcracks and recast layers while maintaining a narrow groove width is attributed to the high-speed waterjet's cooling and material removal capabilities.
