The friction and wear test results show that adding Zr alloy layers can effectively improve the wear resistance of 45 steel. At the same time, in the electrochemical test, Zr alloy layers have good impedance effect and corrosion resistance to 45 steel. The mid-term results show that adding Zr alloy layers can significantly improve the durability and service life of 45 steel, providing a feasible solution for the protection of high-load components such as aviation engines.Keywords: 45 steel; Zr alloy layer; friction and wear performance; electrochemical properties.
