Apr 1, 2013 · The CrN and CrCN coatings were deposited from a pure Cr target (99.99%) in pure nitrogen (99.99% N) atmosphere at an arc current of 80 A for 100 min. The N 2 gas partial pressure was kept constant at 1.8 Pa. In case of CrCN coatings acetylene was added and a flow rate of 10 sccm was controlled by an MKS 100 mass flow controller.
