A device to perform a corrosion and wear test in a slurry comprises: a chamber in which slurry is stored; and a driving part capable of rubbing a test piece mounted to measure the corrosion and wear of the test piece caused by the slurry with the slurry by rotating the test piece in the slurry of the chamber, and adjusting an angle collided with the slurry particles. The present invention rubs the test piece with the slurry by rotating the test piece in the slurry of the chamber, and enables to control the angle collided with the slurry particles since one surface of the test piece forms a preset angle to the tangential direction of a concentric rotation circle in a rotational direction in accordance to the test conditions. Also, the present invention can prevent the edge of the test piece from being eccentrically corroded and worn since a fixing holder holds the test piece in a state of surrounding the edge of the test piece. Moreover, the present invention can control the slurry of the chamber to be at a set temperature while having a preset oxygen concentration in the corrosion, and wear test conditions using a temperature control part and a gas control part. Accordingly, the present invention can accurately and easily measure the corrosion and wear characteristics of the materials in a slurry environment in which an abrasive is mixed with fluid. |
