Liquid-liquid Bimetal Forming Process and Its Application in Wear-resistant Materials

With the rapid development of industrial technology, the service environment of wear-resistant parts such as hammer head, lining plate and jaw plate are more and more stringent. Liquid-liquid bimetal composite technology with a unique interface bonding mechanism, firmly composite highly wear resistance and high toughness metal, and then greatly improves the comprehensive performance of bimetal wear-resistant materials . The application of liquid-liquid bimetal technology breaks through the limitation of traditional process and opens a new idea for the manufacture of high-performance wear-resistant parts. In this paper, the basic principles and characteristics of liquid-liquid bimetal forming process are reviewed, and the technical difficulties, development level and application status of bimetal composite technology are emphatically introduced. In view of the coupling characteristics of temperature field and flow field at the interface of dual-liquid metal composite, it is proposed that the establishment and improvement of process data package and continuous optimization of process parameters will become the future research focus and development direction of liquid-liquid bimetal forming process.
