Description

technical field

[0001] The invention relates to a multi-element zinc-aluminum alloy wire and a manufacturing method thereof, in particular to a zinc-aluminum alloy wire containing Ce and Nd and a manufacturing method thereof. Background technique

[0002] As we all know, except for a few precious metals, metal materials will undergo chemical and electrochemical reactions with the surrounding medium and suffer from corrosion. Metal corrosion has become the greatest hazard to large steel structures, seriously affecting their safety and life. In addition, the wear and tear caused by various mechanical actions on the metal surface is also extremely serious. A large number of metal components fail due to corrosion and wear, resulting in great waste and loss. According to the statistics of some industrially developed countries, the annual loss of steel due to corrosion and wear accounts for about 10% of the total steel output, and the amount of loss accounts for about 2-4% of th...
