“…Corrosion parameters, such as corrosion potential (Ecorr), corrosion current density (Icorr), anodic, and cathodic Tafel slopes (βa and βb) were obtained by using Tafel extrapolation method. The equation of Stern–Geary 28 was used to calculate the polarization resistance (Rp). The obtained results are shown in Table 6The carbonitrided layer C2 showed a more significant change towards the more noble direction when compared to the carbonitrided layer C1.…”

The present paper investigates the friction and wear resistance of carbonitrided AISI 4130 steels using single and multi-pass scratch techniques. The influence of carbon concentration in high-temperature gas carbonitriding on friction, wear, and corrosion behavior was studied. The microstructure and morphological properties of carbonitrided layers were investigated employing optical microscope and XRD. The corrosion performance of carbonitrided layers was also evaluated using potentiodynamic polarization in 3.5 wt.% aqueous solution of NaCl. The results of microstructure showed the formation of an arrangement of carbonitrides, chromium nitride, retained austenite, and [Formula: see text] carbides phases in the carbonitrided layers. The carbonitrided layer microhardness increased as a function of increasing carbon concentration to attain a maximum value of about 980 HV0.1 at a carbon content between 1 and 1.2%. The microhardness value was more than 3 times than those of the untreated AISI 4130 steels. Moreover, carbon content has a significant influence on the scratch resistance. For single pass, a critical load (LC1) of about 3.5 N was found. The use of multi-pass scratching allowed to examine friction coefficient, wear volume, and damage mechanism. Carbonitrided layers revealed a low friction coefficient (0.06) and a low wear volume that does not exceed [Formula: see text]. Moreover, the multi-pass scratch technique can extract valuable information about the wear behavior of the carbonitrided layers. The results of corrosion test showed that the formation of [Formula: see text], [Formula: see text] and chromium nitride phases in carbonitrided layers were at the origin of high electrochemical resistance.

The aim of this work was to investigate the nanomechanical, adhesion and corrosion resistance of hydroxyapatite (HAP) coatings. The electrodeposition process was used to elaborate the HAP coatings on Ti6Al4V alloy. The effect of hydrogen peroxide concentration H2O2 on the electrolyte and the heat treatment was studied. Surface morphology of HAP coatings was assessed, before and after heat treatment, by scanning electron microscopy associated with X-ray microanalysis (SEM-EDXS). Moreover, X-ray diffraction (XRD) was performed to identify the coatings’ phases and composition. Nanoindentation and scratch tests were performed for nanomechanical and adhesion behavior analysis. The corrosion resistance of the uncoated, the as-deposited, and the heat-treated coatings was investigated by electrochemical test. The obtained results revealed that, with 9% of H2O2 and after heat treatment, the HAP film exhibited a compact and homogeneous microstructure. The film also showed a crystal growth: stoichiometric hydroxyapatite (HAP) and β-tricalcium phosphate (β-TCP). After heat treatment, the nanomechanical properties (H, E) were increased from 117 ± 7 MPa and 24 ± 1 GPa to 171 ± 10 MPa and 38 ± 1.5 GPa respectively. Critical loads (LC1, LC2, and LC3) were increased from 0.78 ± 0.04, 1.6 ± 0.01, and 4 ± 0.23 N to 1.45 ± 0.08, 2.46 ± 0.14, and 4.35 ± 0.25 N (respectively). Furthermore, the adhesion strength increased from 8 to 13 MPa after heat treatment. The HAP heat-treated samples showed higher corrosion resistance (Rp = 65.85 kΩ/cm2; Icorr = 0.63 µA/cm2; Ecorr = −167 mV/ECS) compared to as-deposited and uncoated samples.

“…They also have optical properties, such as an optical bandgap of over 3 eV and an average transmittance of about 85 % in the visible light range (Mei et al, 2020). In solar cell manufacturing, TCOs play an essential role as they are used as thin films in the front contacts to provide a transparent window for the transmission of light, the generation of photocurrent from the active layer to an external circuit, and the collection of electric current (G-Berasategui et al, 2015;Saive et al, 2016).…”

In this work, thin films with a ZnO:Al/Ag/ZnO:Al multilayer structure were deposited by radio frequency (RF) and pulsed DC sources in a magnetron sputtering system on glass substrates at 50 °C with different deposition times of the Ag layer. The results showed that the thin films' properties improved with increasing the deposition time of the silver metallic interlayer and with thermal treatment at 300 °C for one hour. The highest average transmittance in the visible range was 89 %. The best values of resistivity and conductivity were 10-4 Ω·cm and 103 Ω-1cm-1, respectively. Finally, the XRD patterns showed that with an increase in the Ag layer's deposition time, the plane's peak (111) belonging to the Ag plane was observed.
