Galling is when a type of metal is damage caused by abrasive wear. When particles separate from metal when they are sliding from one machine to the other, it creates scratches on the metal. While they may be small, they can be detrimental and may require immediate maintenance. There were experiments taken to see if there was galling threshold. The edge and the middle were to two areas that was found to have some sort of galling.
- Galling is when you a surface has damage caused by abrasive wear.
- Universities have been studying this using the U bend process to check the abrasive damage.
- They found a galling threshold by using a black holder and high pressure nitrogen cylinders.
“Galling is a type of die surface damage that differs from the typical deterioration of a surface caused by abrasive wear.”
