The method is an application in the obtaining metal and non-metal coatings with increased corrosion, chemical and mechanical resistance. It is an accelerated method with enhanced possibilities for combining the saturating element and the substrate and for regulating the structure and the phase composition of the coating within a wide range. The method includes the reaching of an initial vacuum -10<-3>x10<-1>Pa, thermal cleaning of the articles at 800-1200 degrees C for 5-20 minutes, establishing inert atmosphere at pressure of 10<-1>x1 Pa, ionic stripping for 5-20 minutes followed by magnetron sputtering combined with ion plating at a negative potential of the substrates 100-500 V. If necessary the corresponding gas is added for reaction sputtering.
