Why did the USB cable plug rust before long?

The phenomenon that the USB data cable plug is easy to rust is directly related to the electroplated coating of the USB data cable plug. The electroplating layer on the metal surface of USB plug can reach the standard thickness and quality, so it is not easy to rust. If the plating layer is poor, it is easy to rust. The quality of electrodeposited coating is a measure of the ability of metal surface to resist oxidation and rust.

The ability of anti-oxidation and rust of electrodeposited coating is graded by salt spray test in the industry. The routine is divided into 8-hour salt spray test, 12-hour salt spray test, 24-hour salt spray test and 48-hour salt spray test. The longer the salt spray test, the stronger the anti-oxidation and rust ability, and it is not easy to rust.
