タングステンカーバイドの深冷処理:プロセス、利点、および用途
Cryogenic Treatment of Tungsten Carbide: Process, Benefits & Applications Tungsten carbide combines high hardness, high strength, and excellent wear resistance, making it widely used in cutting tools, cold-working dies, and various wear-resistant components. However, during the cooling phase of sintering, the significant difference in thermal expansion coefficients between the WC hard phase and the Co binder phase results in substantial residual internal stress. Furthermore, the phase composition and distribution of the cobalt binder directly determine the material’s strength-toughness balance. As a supplementary post-processing technique, cryogenic treatment effectively optimizes microstructure and stress states, serving as a crucial method for enhancing the service performance of Tungsten carbide.
