“…Corrosion behavior of Al in water-organic solvent mixtures containing HCl was reported by Abd-El-Nabey et al, and they showed that the corrosion rate depends on the structure of the water-alcohol mixtures [2]. Zaharieva et al worked on the corrosion of Al and its alloys in ethylene glycol (EG)-water mixtures, and showed significant corrosive action of glycolic acid and a protective effect of sebacic acid on Al corrosion [3]. Both Al corrosion and hydrogen evolution in the alkoxide reaction has been investigated.…”

“…The mechanically polished specimens were immersed in 20 cm 3 of MEEE and BEEE at 399 -415 K for up to t i = 24 h (t i : immersion time). The temperature of the MEEE and BEEE was controlled with a silicone oil bath (PS-1000, Tokyo Rika-kikai).…”

“…Time-variations in the rest potential of the specimens, E vs. t i (E: rest potential), were measured during immersion in 100 cm 3 Table 2 shows the mass changes, ΔW (= W 2 -W 1 ), and corrosion coefficients, ΔW/W 1 , on nine kinds of Al alloys immersed in MEEE and BEEE at 415 K for 24 h. Specimens-13 and -15 show large mass losses in MEEE, while only Specimen-15 shows large mass losses in BEEE. In the immersion of the specimens which showed large mass losses of ΔW/W 1 = -0.26 to -0.37, gas evolution started on the surface of the specimens at about t i = 1 h, and the transparent MEEE and BEEE changed to a brownish color, becoming darker with t i .…”

“…Fig. 1 shows the time-variations in the rest potential, E, of Specimens-10, -13, and -15 during immersion in 100 cm 3 of MEEE at 415 K with stirring. The E value of Specimen-10 gradually rises with immersion time, t i , to a steady value of -0.2 V (vs. Pt) at t i = 10 h. Specimen-10 after immersion for 24 h showed a shining surface, similar to that before the immersion test.…”

“…2Al + 6ROH = 2Al(OR) 3 + 3H 2 (1) The reaction leads to the formation of Al alkoxide, Al(OR) 3 , with hydrogen gas evolution, H 2 , and is well known as the "alkoxide reaction". Tsuchida examined the effect of alcohol-mixing on the corrosion of pure Al for 72 h at 353 -393 K, and found that the corrosion of Al was accelerated by mixing different kinds of alcohols [1].…”

Corrosion of Al–Sn–Bi alloys in alcohol at high temperatures. Part I: Effects of the metallurgical structure of the alloys and the metal salt additions to alcohol

Corrosion of free machining Al alloys that contain Sn and Bi was investigated at 391-415K in 2-(2-(2-methoxyethoxy)ethoxy)ethanol (MEEE) and 2-(2-(2-butoxyethoxy)ethoxy)ethanol (BEEE) with/without SnCl 2 , Sn(OC 2 H 5 ) 4 , FeCl 3 , and CuCl 2 . The Al-Sn-Bi alloy displayed severe pitting corrosion in MEEE as did the Al-Sn alloy in BEEE at 415K, and Sn and Sn/Bi were enriched on the surface of pits. Immersion tests of pure Al in MEEE containing Sn/Cu-salts at 415K also showed severe corrosion and the deposition of metallic Sn and Cu on the surface. The corrosion mechanisms are discussed in terms of the electro-catalytic activity of the Sn enriched on the surface.

The corrosion behaviors of AA6061 alloy in ethylene glycol (EG)–water solution were investigated by weight‐loss test and electrochemical measurement. The surface morphology observation and composition analysis were performed by scanning electron microscopy (SEM) and energy dispersive X‐ray (EDX) spectroscopy. After weight‐loss test, the pH of EG–water solution increased. The presence of glycolic acid (GA) enhanced the corrosion susceptibility of AA6061 alloy. The higher pH value intensified the aggressive action of GA to AA6061 alloy. GA forms a complex with aluminum ions and its negative charge centers of oxygen atom plays a key role for the complex formation.

In this study, the inhibiting effect of cerium ions (Ce 3? ) on corrosion of 3003 aluminum alloy (AA3003) in ethylene glycol-water solutions was investigated using a rotating cylinder electrode, simulating the hydrodynamic condition of the automotive cooling system. Electrochemical measurements and surface characterization were conducted to study the inhibiting mechanism of Ce 3? on the Al alloy corrosion. It is found that Ce 3? serves as a cathodic inhibitor, and inhibits effectively corrosion of AA3003 in the flowing ethylene glycol-water solutions. The inhibiting effect of Ce 3? is resulted from the formation and deposit of Ce oxide and/or Ce hydroxide on the electrode surface. With the immersion time, the Ce deposit layer increases its thickness to cover the second phase particles, eliminating the galvanic coupling effect between the second phase particles and Al alloy substrate.
