Today, the 6061 aluminum tube manufacturer will introduce to you the surface treatment process of the 6061 aluminum tube and the influence of adding tin on the modification process of magnesium alloy.
1.6061 Aluminum tube surface pretreatment.There is oxide layer on the surface of the 6061 aluminum tube, which seriously hinders its recombination with magnesium alloy.The surface of the 6061 aluminum tube is coated with a layer of coating to prevent the secondary oxidation of the 6061 aluminum tube while removing the oxide layer on the surface of the 6061 aluminum tube by means of tin dipping process, zincate process and electric galvanizing process.The results show that the pretreatment can effectively remove the oxide layer on the surface of 6061 aluminum alloy and improve the wettability of the composite effectively.
2. Magnesium alloy modification.Tin was introduced in 6061 aluminum alloy leaching treatment and magnesium alloy adding tin modification treatment, indicating that the addition of Sn can refine the structure of the transition layer, and the dispersed Mg2Sn can effectively improve the structure and performance of the interface transition layer.
3. Interface shear strength performance.The composite sample test results showed that Sn hindered the diffusion of Mg, prevented it from forming crystal nucleus smoothly, and inhibited the growth of grains.The massive Mg2Sn has a positive effect on improving the microstructure and properties of the transition layer.An increase in Sn content gives a greater strength when the amount of Sn added is 1%.
The above is about the influence of the surface treatment of 6061 aluminum tube and the process of adding tin. If you need 6061 aluminum tube, please contact us.
