Engine
The engine crankshaft oil seal prevents the engine oil from leaking from the engine and prevents foreign matters from entering the engine. Crankshaft oil seal is one of the engine parts. It contacts with oil at high temperature, so it is necessary to use materials with good heat resistance and oil resistance. At present, polytetrafluoroethylene is widely used in high-grade cars. With the continuous improvement of automobile performance requirements, more and more manufacturers have gradually used this material, and its application prospect is very wide.
Polytetrafluoroethylene (PTFE) material has an excellent performance in various aspects, such as high-temperature resistance, corrosion resistance, nonstick, self-lubricating, excellent dielectric properties, and low friction coefficient. However, the surface activity of untreated PTFE material is poor, and the bonding between one end and metal is very difficult, so the product can not meet the quality requirements. In order to solve this technical problem, it is necessary to try to change the surface properties of PTFE (polytetrafluoroethylene) and metal bonding, but not to affect the performance of the other side. Although Lena's solution can improve the bonding effect to a certain extent, it changes the properties of PTFE. It is proved by experiments that the surface activity of PTFE which needs to be bonded is obviously enhanced after plasma bombardment, and the bonding between PTFE and metal is firm and reliable, which can meet the requirements of technology, while the other side keeps the original performance, and its application is more and more widely recognized.
