Corrosion inhibition of AA6060 aluminium alloy by lanthanide salts in chloride solution

Effect of Nd3+ Ion Concentration on the Corrosion Resistance of API X70 Steel in Chloride‐Rich Environments

“…It has been recognized that rare earth salts are low-toxicity compounds whose average lethal dose (LD50) is similar to that of sodium chloride (NaCl) [1][2][3]; therefore, the interest in the use of rare earths has emerged as an alternative to replace those toxic and highly carcinogenic corrosion inhibitors that affect both people and the environment, and many of these dangerous inhibitors are based on chromates (CrO 2− 4 ), mercurate, nitrite, and alkynol [4]. Most of the studies have been reported based on the use of both Ce and La salts as corrosion inhibitors, in the form of either chlorides, nitrates, or other salts [2,[4][5][6][7][8][9]. Many of these studies have been carried out in chloride-rich solutions, and the excellent corrosion inhibiting capacity of rare earth salts has been attributed to the high reactivity of rare earths.…”

Protection against corrosion in marine environments of AA6060 aluminium alloy by cerium chlorides

“…In a recent paper, the ability of lanthanide salts, especially cerium, as blocker of the cathodic reaction in the corrosion process of AA6060 in 3.5% NaCl has been demonstrated [22]. The present work reports on the results obtained in the study of cerium chloride as inhibitor of the pitting corrosion of AA6060 in 3.5% NaCl.…”

“…Corresponding electrochemical parameters are reported in Table 3. In this table, we have also reported the corrosion rate values corresponding to the blank (i 0 cor ) [22]. Results obtained show that the maintenance of the samples to the abandonment during 24 and 48 h reinforces the capacity of cerium inhibition.…”

Electrochemical investigation of the epoxy nanocomposites containing MnAl2O4 and CoAl2O4 nanopigments applied on the aluminum alloy 1050

“…[1][2][3][4] Therefore, they are catalytic sites for the cathodic reactions and nucleation of pits. [5][6][7] AA1050 has been used in conventional engineering applications, i.e., architectural, automotive industries, containers, and equipment for the food and chemical industries, where corrosion resistance is required and the mechanical strength is relatively unimportant. Therefore, the improvement of the corrosion resistance of AA1050 has been under the attention of the researchers in recent years.…”
