Various surface treatments; including thermally sprayed ceramic coatings, titanium nitride (TiN) deposited by physical vapour deposition and nitrogen implantation processes, have been applied to combs and cutters that are used for wool severence. A series of laboratory and field tests have been carried out to evaluate the relative merits of the different treatments.
