I performed a dry ball-on-disk wear test on In-718 plate, but in my wear profile, I am getting a "hump" in the middle of the wear track. By looking at the SEM images, it appears that this extra material that forms the "hump" is not uneroded material, but is just In-718 that has adhered to the wear track.
Does anyone know of any methods to remove this adhered material on the track? It could be mechanical or chemical, but my objective is to remove this material to get the proper profile of the wear track.
It will be welded I guess. If so, it is difficult to remove it. Moreover, I recommend leaving it as it is, as you might end up removing excess of material along with it. Just defend the way it is.
I am not sure if you should remove it. It could be wear debris adhered as well. It is known that wear debris can get adhered forming a glazed surface during wear tests. I think you can rather think about why it is forming the bump and then write accordingly in your manuscript.
