Why do tungsten carbide cutters have such good chemical stability? This is closely related to their microstructure. Through the analysis of the microstructure, we can find that tungsten carbide itself has a compact crystal structure, which makes it difficult for chemical substances to invade, thereby endowing the cutters with good corrosion resistance. In addition, the chemical composition of tungsten carbide cutters also plays an important role in their chemical stability. Tungsten carbide cutters with different chemical compositions may vary in chemical stability. For example, adding certain trace elements or alloying components may further improve their corrosion resistance.
