Investigation of DLC Coating and its Influence on the Mechanical Properties of Titanium Alloy TI-6AL-4V by means of Automated Ball Indentation Test
Original language description
The substrate of titanium alloy Ti-6Al-4V coated with hard 300 nm thick diamond-like carbon (DLC) coating was selected as coating/substrate system with high gradient of hardness and moderate adhesion for the investigation of elastic modulus using ball indentation. The work shows the potential of macro-methods, where large contact area between ball indenter and the surface of studied material enables the investigation of mechanical properties of coating/substrate system at higher loads, which may be effective when studying thin coatings and its contribution to the mechanical properties of the substrate. The indentation with the use of 10 mm ball indenter is capable of determining the global elastic modulus of the given coating/substrate system, while 5mm ball indenter enables the measurement of elastic modulus of the coating separately from the substrate.
