“…In the literature, the single phase of the TiN coating was generally obtained with various N 2 pressures, since TiN was stable across a wide stoichiometric range. [11][12][13][14][15][16][17][18][19] The grain morphology of the TiN coating was columnar (Figure 4). The columnar grain boundaries in the TiN coatings, aligned perpendicularly from the topmost surface down to the substrate/coating interface (Figure 4), were considered to be an easy path for the penetration of the electrolyte.…”

“…[9][10][11][12][13][14][15][16] Even though the widely accepted pitting corrosion mechanism of the TiN-coated substrate in the literature was local galvanic corrosion through the galvanic coupling of the TiN coating and the substrate, there remain questions about the mechanism of pitting formation and the growth of the pitting corrosion. One of the key parameters for galvanic corrosion is defects in the coatings, such as pin holes and micro and macro porosities in the coatings.…”

“…The defects in the coatings provide the electrolyte with a path to the coating/ substrate interface. [9][10][11][12][13][14][15][16] Martensitic stainless steels (EN 1.4034 was used in this work) that are generally used for the blades in kitchen appliances were coated for both decorative and wear-resistance requirements. The pitting corrosion of the TiN coating deposited by arc PVD on a stainlesssteel substrate was studied in detail with the corrosion potential (Cor.Pot), the polarization resistance (PR) and electrochemical impedance spectroscopy (EIS) techniques.…”

TiN coatings deposited by arc PVD were characterized by XRD and SEM. In-situ measurements of the corrosion of the substrate and the TiN-coated substrate were made using the corrosion potential (Cor.Pot.), the polarization resistance (PR) method and electrochemical impedance spectroscopy (EIS) in a 3 % NaCl solution as a function of the immersion time. The semiconductor scale formed on the TiN was identified using a Mott-Shottky analysis as an n-type semiconductor with a flat band potential of -0.83 V vs. SCE. The TiN coating (0.5 μm thick) consisted of cubic TiN exhibiting columnar grains, pin holes, voids and porosities. The pitting corrosion of the TiN, observed visually between 1 h and 2 h, was captured by EIS and PR. The electrical circuit (EC) model used for the EIS data supported the degradation of the coating through pitting corrosion, in agreement with the visual observations. The corrosion resistance (polarization resistance) determined by the polarization resistance method (Rp) and the EIS (Rtotal) decreased suddenly during the pitting corrosion. The corrosion resistance of the TiN-coated substrate was greater than the corrosion resistance of the substrate during the approximately 24 h of exposure. Keywords: stainless steel, TiN, coating, EIS, polarization resistance, pitting corrosion Prevleka TiN, nanesena z oblo~nim PVD-postopkom, je bila pregledana z XRD in SEM. In-situ meritve korozije podlage in podlage s prevleko iz TiN so bile izvr{ene z metodo korozijskega potenciala (Cor.Pot.), polarizacijske upornosti (PR) in z elektrokemijsko impedan~no spektroskopijo (EIS) v 3-odstotni raztopini NaCl v odvisnosti od~asa namakanja. Mott-Shottkyjeva analiza je odkrila nastanek n-tipa polprevodne {kaje na TiN s potencialom ravnih nivojev -0.83 V proti SCE. Prevleko TiN (debeline 0,5 μm) sestavljajo kubi~ni TiN s stebrastimi zrni, luknjami, prazninami in poroznostjo. Vidno odkrita jami~asta korozija TiN, opa`ena med 1 h in 2 h, je bila posneta z EIS in PR. Model elektri~nega tokokroga (EC), ki je bil uporabljen za EIS-podatke, podpira degradacijo prevleke z jami~asto korozijo, skladno z vizualnimi opa`anji. Korozijska upornost (polarizacijska upornost), dolo~ena z metodo polarizacijske upornosti (Rp) in EIS (Rtotal) se je nenadno zmanj{ala med jami~asto korozijo. Korozijska upornost podlage z nanosom TiN je bila ve~ja kot korozijska obstojnost podlage med izpostavitvijo okrog 24 h.
