OSA | Mechanism and morphology control of …

Silicon carbide (SiC) ceramics have been widely used for microelectronics, aerospace, and other industrial fields due to their excellent chemical stability and thermal tolerance. However, hard machinability and low machining precision of SiC ceramics are the key limitations for their further appliions. To address this issue, a novel method of underwater femtosecond laser machining was

What are carbide tips? | HowSfWorks

Carbide (or more specifically tungsten carbide and titanium carbide) is a very common material on any sort of cutting tool: For example, saw blades, lathe bits, drill bits, router bits and dental drilling tips are generally made of carbide.Carbide is so popular in these sorts of tools because it stays sharper longer than most other materials. Additionally, some ball-point pens use carbide
