“…Higher corrosion resistance has also been reported for this phase 17,28,38,39 . In Figure 2A,B, the presence of grooves on the TiN single‐layer coating with a coarse columnar structure caused the easy diffusion of the corrosive materials through the grain boundary and the direct diffusion route to the substrate surface 17 . Hence, the grooves and porosities (circles) were the likely places for corrosion.…”

“…Triple nitride coatings on the Cr base can prevent oxygen diffusion into the coating by forming dense protective oxides like Cr 2 O 3 and Al 2 O 3 , improving the corrosion properties of the coating. Also, chrome oxide layers are denser than titanium oxide layers, so nitride coatings on the chromium base can have a higher corrosion resistance 5,17,18 . Hence, more advanced coatings, like CrAlN multilayer coatings, have a better performance than the simple nitrides 12,19‐22 .…”

The use of physical vapor deposition (PVD) for hard coatings, especially Al 2 O 3 , TiN, and CrN coatings, has been considered as an ideal method in the coating. Among hard compounds, TiN, due to high hardness, high chemical and physical stability, and low electrical resistance, has been utilized as a popular coating in the industries in the recent decades. [1][2][3] The significant decrease in the TiN coating hardness, its low resistance to oxidation at temperatures higher than 500°C (work temperature restriction), and its low corrosion resistance to corrosive environments are, however, among the most important disadvantages of this coating. 4,5 CrN coating has been introduced as an appropriate substitute for TiN. This is because of the higher fracture toughness, more corrosion resistance and also a lower friction coefficient for the CrN coatings, as compared to TiN coatings. One of the most noteworthy disadvantages of CrN coatings is their low hardness. Many studies have been carried out to improve the CrN hardness. 4,6 In this regard, multicomponent and multilayer coatings have been studied; by producing CrAlN, TiCN, TiAlN, and TiCrAlN new coatings, a significant step has been taken toward the development of hard and corrosion-resistant coatings. 7-10 Addition of aluminum to transition metal nitrides has led to a new group of hard coatings improving oxidation and corrosion behavior, thermal stability, and their hardness. [11][12][13][14][15][16] Triple nitride coatings on the Cr base can prevent oxygen diffusion into the coating by forming dense protective oxides like Cr 2 O 3 and Al 2 O 3 , improving the corrosion properties of the coating. Also, chrome oxide layers are denser than titanium oxide layers, so nitride coatings on the chromium base can have a higher corrosion resistance. 5,17,18 Hence, more advanced coatings, like CrAlN multilayer coatings, have a better performance than the simple nitrides. 12,[19][20][21][22] It has been found out that

“…The BWMS manufacturers offer 40 μm ballast water self-cleaning filters made of stainless steel 304L, 316L for standard applications [10]. These facts typically cause the demand for the improved resistance of exposed components to reduce the expenditures for the required periodic shutdowns and repairs [11], [12].…”

The electrochemical impedance spectroscopy (EIS) and corrosion behaviour of physical vapour deposited (PVD) TiAlN and TiCN coatings of 50 µm mesh shaped AISI 316 stainless steel were estimated under simulated marine conditions (3.5 wt. % NaCl solution). The coatings were prepared by creating adhesive Cr-CrN interlayer with the thickness of about 0.3 µm. The obtained thicknesses of produced coatings were measured to be in a range between 2 and 3.5 µm. The presence of protective coatings leads to corrosion potential (Ecorr ) shifting to more positive values as compared to the bare stainless steel. This effect indicates higher protection efficiency of coated steel under marine conditions. The protective behaviour of produced coating leads to the decreased corrosion current density (jcorr ) by indicating up to 40-fold higher polarization resistance as compared to resistance of the naturally formed oxide layer over the stainless steel. The Nyquist and Bode plots were obtained with the help of EIS measurements by applying alternating potential amplitude of 10 mV on observed Ecorr . The obtained plots were fitted by appropriate equivalent circuits to calculate pore resistance, charge transfer resistance and capacitance. The present study reveals that pore resistance was the highest in the case of TiCN coating (Rpore =3.22 kΩ·cm2). The increase in duration of the immersion up to 24 h leads to change in the capacitive behaviour of the coatings caused by the penetration of the aqueous solution into pore system of TiCN coating with low wettability and surface passivation of reactive TiAlN coating. The presence of defects was confirmed by examining the obtained samples with the help of the scanning electron microscope.
