Vanadis 4 Extra is however also very suitable for blanking and forming of Ultra High Strength Steel Sheet, these materials place high demands on the tool steel regarding abrasive wear resistance and ductility.
12.
The abrasive wear of ENP films are typically measured by applying a mechanical action of an abrasive, rotating wheel on the plated surface and measuring the weight loss ( in milligrams ) of the coating at intervals of 1000 cycles.
13.
Under certain conditions ( potentially due to non-ideal conditions of sliding speed, load, temperature or oxide chemistry / composition ), the oxide may not sinter together and instead the loose oxide debris may assist or enhance the removal of material by abrasive wear.
14.
For example, a coating of only 2 ?m thickness of " ta-C " increases the resistance of common ( i . e ., type 304 ) stainless steel against abrasive wear; changing its lifetime in such service from one week to 85 years.
