Whether steel or cast iron, traditional methods of enhancing their wear resistance have become increasingly challenging. On one hand, further adding alloying elements leads to a sharp increase in costs. On the other hand, high-entropy alloys face difficulties in preparation processes and the challenge of machining precise shapes due to their high hardness. To address this issue, composite materials with metal matrix and high-hardness hard alloys/ceramics as the reinforcing phase have been developed to meet the growing demand for performance. Iron-based composite materials, like pearls on the crown of wear resistance, are an important area of ​​development pursued by both academia and industry. Meanwhile, GESION is committed to seeking alternatives to WC-Co-based hard alloys and promoting the application of non-WC-Co-based hard alloy composite materials to reduce the use of scarce resources such as tungsten and cobalt, thus promoting environmentally friendly and sustainable development.
