Abstract

In order to explore the interfacial bonding properties of multi-layered metal composites in depth, using ZChSnSb8-4 alloy as research object, instead of atomic substitution modeling, taking into consideration of the content ratios of Cu6Sn5, SnSb and Sn in the alloy, crystal structure modeling using material composition method was built with molecular dynamics simulation software of Materials Studio, the bonding properties of the interface between steel body and Babbitt alloy with or without Sn layer were simulated and analyzed respectively. The interfacial bonding energy of steel and Babbitt alloy with or without Sn layer was calculated under the same conditions. At the same time, the bonding energy between the adjacent alloy interfaces of the structure with or without Sn layer was calculated and analyzed, the formula for calculating the interface bonding energy of multi-layered alloy materials is put forward, and the basis for judging the dangerous interface is given. The simulation results show that the minimum interfacial bonding energy of the three-layer material is 39.92% higher than that of the two-layer material. Therefore, the three-layer structure bushing has better bonding performance and is less likely to be destroyed in engineering practice. Meanwhile, it is demonstrated that when the temperature is 543.15K, the interfacial bonding energy of the bushing is the maximum, and the interfacial bonding performance is the optimal.
