Tribological properties of duplex treated TiN/TiCN coatings on plasma nitrided PH15-5 steel

A study of the wear performance of duplex treated commercial low-alloy steel against alumina and WC balls

“…Therefore, interfacial engineering is necessary to enhance the tribo-mechanical properties of the coating/substrate system. Duplex treatments have been applied to improve adhesion between different steel substrates and various hard coatings, and to enhance the tribological performance [2]. Duplex treatments can be classified as modern technological processes, respecting the environment while ensuring the required properties.…”

Structure and mechanical properties of low temperature magnetron sputtered nanocrystalline (nc-)Ti(N,C)/amorphous diamond like carbon (a-C:H) coatings

“…pre-nitriding and/or multilayer TiN/TiCN coatings [13,14] with a beneficial load bearing support being offered by the hard TiN interfacial layer. The TiN layer can also beneficially act as a diffusion barrier between the TiCN layer and the substrate at elevated temperatures [12]. An approach to demonstrate the amount of energy dissipated under oscillating loaded sliding contact conditions using classical Wohler fatigue fretting curves showed that the amount of dissipated energy is significantly reduced after a large number of cycles for single layer TiN and TiCN coatings, due to cracking phenomena [15].…”

Corrosion Behaviour of a SiOxNy Coated and Nitrided PH Stainless Steel

“…The nitrided layer plus the hard coating can be a good combination to resist the erosion test. It is possible that this behavior is related not only to the hardness but also to the fracture toughness and resistance to plastic deformation of the nitrided layer and of the coating as it was pointed out by Zukerman et al (2007) and Bousser et al (2008). The erosion behaviour of the coated sample was similar to the only aged PH steel since the mass loss was 3% lower than in the P sample ( Fig.…”
