A device for evaluation of shock-abrasive wear resistance of weld metal consists of a bunker, a counterbody, a lever, a tray, a container and a weight, the counterbody has irregular shape, a magnet is used for collection of used metal, and evaluation of shock-abrasive wear resistance is conducted by the following expressions:,,where U - coefficient of impact wear resistance;А - coefficient of abrasive wear resistance;- mass of model worn by impact load;- total worn mass of model. |
