Corrosion-electrochemical study in 0,9% NaCl physiological solution of the steel 12Х18Н10Т sub- jected to ion-plasma treatment on different flowsheet processes was made. It is set that most effectively pit- ting-resistance of substrate rises when use of combine technology – ionic nitriding and arc deposition (КИБ) of titanium nitride Advantage of processed steel is increased in relation to initial depending of stay measure in a corrosion environment.
