Abstract: 

THE MOLYBDENUM NITRIDE COATING WAS PRODUCED BY NITROGEN ION IMPLANTATION INTO MOLYBDENUM LAYER DEPOSITED ON THE STAINLESS STEEL 316. AT FIRST, MOLYBDENUM IS DEPOSITED ON THE STAINLESS STEEL BY ION BEAM SPUTTERING METHOD. THE THICKNESS OF AS-DEPOSITED MO FILMS FOR THE SUBSTRATES PREPARED AT 12 MIN WAS 500 NM. THEN NITROGEN IONS OF 30 K EV WITH THE DOSE OF 1´1017, 8´1017 AND 12´1017 N+ IONS CM-2 WERE IMPLANTED IN AS-DEPOSITED FILMS. CRYSTALLINE STRUCTURE AND TOPOGRAPHY OF THE SURFACE ARE INVESTIGATED BY GLANCING INCIDENT X-RAY DIFFRACTION (GI XRD) AND ATOMIC FORCE MICROSCOPY (AFM) RESPECTIVELY. CORROSION TESTS SHOWED CONSIDERABLE IMPROVEMENT OF CORROSION PERFORMANCE OF MOLYBDENUM LAYER BY NITROGEN ION IMPLANTATION AND ALSO WITH INCREASE OF ION DOSES.
