材料组织 MATERIAL STRUCTURE

1.The mixture of modified polytetrafluoroethylene (PTFE) and lead (PB) is 0.01-0.03mm. It is a kind of wear-resistant material. In the process of operation, a transfer film can be formed to protect the counter grinding shaft.
2. Copper powder layer 0.2 ~ 0.30mm can improve the bond strength of PTFE / Pb and steel plate, which has good bearing capacity and wear resistance. At the same time, copper is a good heat conducting material, which can quickly transfer the heat generated in the bearing operation process.
3. Low carbon steel 0.7 ~ 2.3mm, improve bearing capacity and heat transfer.
4. Copper / tin electrodeposited coating, copper coating 0.008mm, tin coating 0.005mm, so that the bearing has a good corrosion resistance function.
