Abstract
An apparatus for identifying metal corrosion includes a metal test piece, a push button timer, a liquid tank, a support, two fixed pulleys, a traction cable, a weight and a vibration motor. The support and the first pulley are in a lower portion of the tank. The second pulley is above the first pulley. The test piece is fixed on the support and connected to a first end of the traction cable which sequentially winds around the pulleys with a second end outside the tank. The weight, on which the motor is fixed, is suspended at the second end. The timer is under the motor. A corrosion solution is added into the tank, and the vibration motor provides alternating stress. When the metal test piece is broken, the weight and the motor are dropped and pressed on the electronic timer to record breaking time of the metal test piece.
