Abstract

The research addresses the influence of bombardment by high-energy ions (Cr + B)+ with a low fluence 4 × 1017 cm-2 on the tribological and mechanical properties of Ti-Al-N coatings. The wear resistance decreases 2.6 times whereas the microhardness decreases 1.2 times. The structural-phase state and the chemical composition of the surface layer of the modified coating are determined. The research is carried out by transmission and scanning of the electron microscopy and the secondary ion mass spectrometry. In the ion-modified coating layer the average concentration of titanium, aluminum and nitrogen decreases and those of chromium and boron increase when at a fluence of 4 × 1017 cm-2 the maximum values of Cr and B reach 16 and 23 at %, respectively, and the minimum values of Ti, Al and N amount to 15, 7 and 39 at %. In this layer the columnar structure is broken; its volume is divided into the alternative local nanosize zone-crystalline and amorphous. The phase composition of the crystalline regions is represented by TiN and AlN phases and a new CrB4 phase. The observed decrease of the tribomechanical properties can be due to both the amorphization of the surface layer and the transformation of a high-strength phase in a brittle one.
