Synergism is a combined action of compounds greater in total effect than the sum of the individual effects. Synergism of corrosion inhibitors is either due to the interaction between components of the inhibitor composition or due to interaction between the inhibitor and one of the ions present in the aqueous solution . Synergistic inhibition is an effective means to improve the inhibitive force of inhibitor, to decrease the amount of usage, and to diversify the application of inhibitor. It plays an important role in not only theoretical research on corrosion inhibitors but also practical work . In previous investigations, synergism between organic inhibitors and halide ions on metal corrosion in acidic solution has been researched by many authors. The synergistic inhibition effects of organic inhibitor/ metallic ion mixture , organic inhibitor/organic inhibitor mixture and inorganic inhibitor/inorganic inhibitormixture on corrosion of metal in acidic media have also been studied. Forsyth et al. have studied the synergistic corrosion inhibition of mild steel by rare earth (RE) Ce3+ and sodium salicylate in 0.1 M NaCl neutral media. Aramaki investigated the synergism of RE Ce3+/inorganic compound Na2Si2O5 mixture and Ce3+/organic compound C8H17S(CH2)2- COONa (NaOTP) mixture on the corrosion of zinc in 0.5 M NaCl. However, there is little report in the literature about the synergism between RE ions and other compounds on metal corrosion in strong acidic media. In our laboratory, much work has been conducted to study the synergism between RE ions and other compounds on the corrosion of some metals and alloys in strong acidic media. In 1996, the synergistic inhibition between anionic surfactant (sodium dodecyl sulfonate, SDS) and La3+ for mild steel corrosion in 1.0 M HCl was reported . Recently, the synergistic effect of Na2MoO4 and Ce4+ on CRS corrosion inhibition in 1.0 M HCl was also investigated . In the present work, the synergism between Ce4+ and organic compound iso-vanillin on CRS in sulfuric acid is first studied by weight loss and potentiodynamicpolarization methods. It is hoped to get general information on synergism between organic inhibitor and RE ion in strong acid solution. [ Last edited by sun072 on 2011-5-26 at 00:57 ] |

Synergism is a combined action of compounds greater in total effect than the sum of the individual effects.协同作用是指多个化合物的组合作用大于单个化合物作用的总和。 Synergism of corrosion inhibitors is either due to the interaction between components of the inhibitor composition or due to interaction between the inhibitor and one of the ions present in the aqueous solution .防腐剂的协同作用或者是由于防腐剂组分间的相互作用，或者是由于防腐剂和水中某种离子之间的相互作用。 Synergistic inhibition is an effective means to improve the inhibitive force of inhibitor, to decrease the amount of usage, and to diversify the application of inhibitor. 协同防腐是一种可有效改进防腐剂的防腐能力、减少防腐剂用量和使防腐剂应用多样化。It plays an important role in not only theoretical research on corrosion inhibitors but also practical work . 不仅在防腐剂理论研究，而且在实际应用领域，协同防腐都具有重要的作用。In previous investigations, synergism between organic inhibitors and halide ions on metal corrosion in acidic solution has been researched by many authors. 在先前的研究中，已有许多研究者就有机防腐剂与卤离子在酸性溶液中金属防腐方面的协同作用进行了研究。The synergistic inhibition effects of organic inhibitor/ metallic ion mixture , organic inhibitor/organic inhibitor mixture and inorganic inhibitor/inorganic inhibitormixture on corrosion of metal in acidic media have also been studied.有关有机防腐剂/金属离子混合物、有机防腐剂/有机防腐剂混合物和有机防腐剂/无机防腐剂混合物各自在酸性媒介中金属防腐方面的协同作用也得到了研究。 前面说的可能不好听，只是希望楼主通过努力，达到更好的使用英语的目的，请不要多想 |
