Development Trend of Surface Treatment Technology for Automobile Lightweight Steel and Parts

In this paper,according to the development trend of high-strength steel parts for automobile lightweight,the characteristics of such steel materials and their development in recent years were dis. cussed. The surface performance requirements of automotive high-strength steel parts and the correspond. ing surface treatment technology were introduced. In particular,the technical developments for various functional requirements such as high corrosion resistance,wear resistance of automotive steel parts used in harsh and severe service environments in recent years were described. It is hoped that automobile lightweight will receive more attention in terms of saving fuel consumption,reducing CO2 emissions,and improving the corrosion resistance of lightweight and high-strength steel parts.
