    The disadvantages of cemented carbide mainly include the following points:

    Hot cracking defects: Carbide is prone to hot cracking at high temperatures. This is mainly because cobalt may react with carbides at high temperatures to form harmful phases, thereby reducing the toughness and reliability of the material Porosity defects: Carbide contains pores. These defects a...
