“…The investigation of corrosion resistance of AlCuFe thin film in NaCl solution approved its excellent performance [19]. The Corrosion behavior investigation of the quasicrystalline Al63Cu25Fe12 alloy in a 5 % sodium chloride solution confirms the formation of a stable quasicrystalline icosahedral () phase [20]. According to corrosion experiments performed for 1, 2, 3, 4, and 8 days using 5% NaCl solution at 293 K, the Al-Cu-Fe films showed excellent corrosion resistance [21].…”

Different industries, including aerospace, marine, and automotive, widely use titanium alloys such as Ti-6Al-4V. Although, this alloy has excellent properties; it is highly susceptible to corrosion and has low thermal stability and tribological characteristics, limiting its application. In this research, after preparing the Al62.5Cu25Fe12.5 quasi-crystalline (QC) powder mixture and appropriate target, the magnetron sputtering method was employed to deposit the QC coating on the Ti-6Al-4V substrate. The powder mixture and AlCuFe thin films were annealed at 700 0 C for 2 h. The scanning electron microscope (SEM) analysis and X-ray diffraction (XRD) methods were used to investigate the microstructure and morphology of mixed powders and Al-Cu-Fe QC coatings. NaCl solution (3.5 wt.%) was utilized to conduct the electrochemical measurements. Al-Cu-Fe thin layer deposited on the Ti-6Al-4V alloy surface without any cracks. The XRD patterns related to the annealed powders and the coating after heat treatment indicated the presence of Cu3Al, AlFe3, and quasi-crystalline ternary phases of Al65Cu20Fe15, Al3Fe, AlTi2, and Al65Cu20Fe15 phases, respectively. Based on the polarization test results, the annealed coating at 700°C showed better electrochemical behavior than the Ti-6Al-4V substrate.

In this research, the mechanical and tribological properties of two deposited metal of Fe-C-Cr-B-Ti alloying systems. In this study, comparative tests of the deposited metal hardfacing by two self-shielded flux-cored wires electrode were carried out: with an exothermic additive (110Cr4Cu5Ti1MnVB) and without an exothermic additive (140Cr15TiSi1MnVB). Abrasive wear resistance was evaluated using a slightly modified procedure on a standardized tribological machine for abrasive wear, according to the limits established by the ASTM G65. The results of studies of the efficiency of introduction of an exothermic addition CuO-Al system into the core filler of a flux-cored wire electrode were presented.

In this work corrosion behavior of the Al72Co18Ni10, Al65Co20Cu15, and Al72Fe15Ni13 alloys forming decagonal quasicrystalline phases was tested in the neutral NaCl solution (pH = 7) which allows a comparison of their corrosion resistance under conditions comparable to application in marine climate. The microstructure of the alloys was studied by quantitative metallographic, X-ray, scanning electron microscopic, and energy dispersive analyses. The corrosion properties were determined by gravimetric and potentiodynamic methods. The Al65Co20Cu15 and Al72Fe15Ni13 alloys have been established to corrode in the sodium chloride solution more strongly than the Al72Co18Ni10 alloy. The corrosion that proceeds under electrochemical mechanism is accompanied by the formation of passive layer on the surface that retards further dissolution in the saline solution after 3–4 days of testing. Scanning electron microscopy shows the marks of pitting corrosion. The pits appear mostly where flaws and boundaries of iron- or aluminum-rich crystalline phases are located. Their quantity and size are lesser on the surface of the Al72Co18Ni10 alloy since Co and Ni in its composition are rate determining for the corrosion processes. This alloy may be recommended as starting material for plasma-spayed coatings working in marine climate.
