Capstan unknown coating
So we have this wire drum for nail production. Diameter is around 500mm and 260mm length. There'a a left over coating on one side of the drum that is dark grey in color. Hardness tester is showing 55HRC and leeb thickness teter is showing 0,2-0,25mm thickness.
I was wondering what kind of coating might it be ? Its does'n seem to have metalic surface of tungsten carbide. Might ir be alumina/titania ?
Would high velocity flame sprayed alumina/titania work here ?
