INFLUENCE OF PLASMA NITRIDING ON THE CORROSION BEHAVIOUR AND ADHESION OF DLC COATINGS DEPOSITED ON AISI 420 STAINLESS STEEL
In this work the corrosion behavior and adhesion of two DLC (“Diamond Like Carbon”) films (“Soft” and “Hard”) were studied. Both coatings were deposited by PACVD (“Plasma Assisted Chemical Vapour Deposition”) on plasma-nitrided and non-nitrided AISI 420 stainless steel. Raman spectroscopy was conduc...

| description | In this work the corrosion behavior and adhesion of two DLC (“Diamond Like Carbon”) films (“Soft” and “Hard”) were studied. Both coatings were deposited by PACVD (“Plasma Assisted Chemical Vapour Deposition”) on plasma-nitrided and non-nitrided AISI 420 stainless steel. Raman spectroscopy was conducted and surface hardness was measured. The microstructure by OM and SEM, was observed. Adhesion tests were performed with C. Rockwell indentation test. Salt Spray and immersion were performed in HCl. The “Soft” coating was 20 μm thick, the “Hard” film was about 2.5 μm. The hardness was of 500 HV in the “Soft” DLC and 1400 HV in the “Hard” DLC. Both coatings presented low friction coefficient and good adhesion when they were deposited on nitrided steel. Also presented good resistance to atmospheric corrosion. HCl DLC degradation slowed rapidly introduced uncoated samples. |
