Tungsten carbide (WC) is a robust material celebrated for its exceptional hardness, wear resistance, and high melting point. These properties make it indispensable in industries ranging from machining and mining to aerospace and electronics. Its ability to maintain structural integrity under extreme conditions has cemented its status as a go-to material for cutting tools, drill bits, wear parts, and high-performance components. However, despite its impressive attributes, tungsten carbide can sometimes benefit from surface modifications to further enhance its performance and lifespan. Anodizing, a surface treatment typically associated with aluminum, has emerged as a potential method for modifying the surface properties of tungsten carbide, improving its polishability, corrosion resistance, and overall durability.
