With the development of modern technology, it is difficult for a single metal to meet the material needs of modern high-tech production. Therefore, it is necessary to develop the connection between materials and integrate the excellent properties of different materials to meet the material needs of industrial production. The connection between tin bronze plate and steel belongs to one of them. Tin bronze plate has good corrosion resistance and high wear resistance and lubrication performance, and is often used as a material for manufacturing bearing parts. In many industrial manufacturing activities, tin bronze plays an important role in determining work performance.
The widely used fusion welding method is difficult to weld steel and tin bronze. This is because the melting and burning of copper alloy elements occur when welding is used, thereby forming pores in the weld, thereby reducing the performance of the work. Therefore, diffusion bonding is generally selected in the connection mode, and the work can be completed well through the verified diffusion bonding technology and selection of process parameters. Tin bronze plate is a non-ferrous metal alloy with the smallest casting shrinkage rate. It can be used to produce castings with complex shapes, clear outlines and low air tightness requirements.
Tin bronze plates are very resistant to corrosion in the atmosphere, sea water, fresh water and steam, and are widely used in steam boilers and marine ship parts. The solidification range of tin bronze plate is large, dendrite segregation is serious; concentrated shrinkage is not easy to form during solidification, and the volume shrinkage is small; tin reverse segregation is easy to appear in the ingot, and white spots can be seen on the surface of the ingot when it is severe, and even tin-rich Particles, generally called tin sweat, improved casting methods and process conditions can reduce the degree of reverse segregation; in liquid alloys, tin is prone to form hard and brittle inclusions SnO2, and smelting must be fully deoxidized to prevent the reduction of alloy mechanical properties caused by inclusions ; It has little sensitivity to overheating and gas, and can be welded and brazed well; no sparks occur during impact, non-magnetic, cold-resistant, and extremely wear-resistant.
