Properties of composite vacuum-arc coatings of the TiN-Ti/TiON structure
Complex investigation of composite coatings with the structure TiN-Ti/TiON is performed in work. It was identified that morphology of the surface of the multilayer coating TiN-Ti provides high adhesion between it and next layer of titanium nitride oxide; three phases in the samples covered with TiN-...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | Complex investigation of composite coatings with the structure TiN-Ti/TiON is performed in work. It was identified that morphology of the surface of the multilayer coating TiN-Ti provides high adhesion between it and next layer of titanium nitride oxide; three phases in the samples covered with TiN-Ti/TiОN and TiОN is revealed TiN with the cubic grating of NaCl type, α-Ti and amorphous titanium oxide TiO₂; at titanium layer thickness in multi-layer system TiN/Ti less than 100 nm sufficiently high mechanical properties are obtained (hardness more than 25 GPa at a plasticity index Н/E* = 0.11…0.12) that at known increase of crack resistance of such coatings make them promising for conditions of high alternating loads; after application of titanium oxynitride of ~ 1 μm thickness on the multilayer coating TiN/Ti of 6 μm (titanium layers – 30 nm, layers TiN – 300 nm) the hardness of the composite coating increases and reachs 27…28 GPa; the first cracks in scrubbing in the coating appear at the load 3.86 N the coefficient of friction does not exceed 0.1; the TiN-Ti/TiON coating has a significantly higher wear resistance than the TiN-Ti coating and in an order greater than the 12Х18Н9Т steel; TiN-Ti/TiON coated samples have high corrosion resistance in a 2% NaCl solution, due to the very low rate of their corrosion, that is a consequence of the structure of the TiN-Ti multilayer coating that has no columnar structure. |
