چکیده

در این تحقیق، پوشش‌های کامپوزیتی Ni-Cu/Al2O3 به روش رسوب‌دهی الکتریکی از حمّام سیترات- آمونیاکی ایجاد شدند. اثر چگالی جریان بر مورفولوژی، ترکیب شیمیایی، سختی و رفتار خوردگی پوشش‌ها مورد بررسی قرار گرفت. مورفولوژی، ترکیب شیمیایی و رفتار خوردگی پوشش‌ها به ترتیب توسّط میکروسکوپ الکترونی روبشی، آنالیز طیف‌سنجی تفکیک انرژی پرتوی ایکس و آزمون پلاریزاسیون تافل مورد بررسی قرار گرفت. نتایج نشان داد که تغییر در چگالی جریان رسوب‌دهی باعث تغییر در ترکیب شیمیایی و مورفولوژی پوشش‌ها می‌شود. همچنین، با افزایش چگالی جریان ریزسختی پوشش‌ها ابتدا افزایش و سپس کاهش می‌یابد، درحالی‌که مقاومت به خوردگی پوشش‌ها کاهش می‌یابد.

چکیده [English]

In this research, Ni-Cu/Al2O3 composite coatings were prepared by electrodeposition from a citrate-ammonia bath; and the effect of deposition current density on the microstructure, hardness and electrochemical corrosion behaviors of the coatings was studied. The results showed that the morphology and composition of the coatings are changed with the current density. Also, by increasing the current density, the microhardness of the coatings is enhanced and then decreased; whereas the corrosion resistance of the prepared coatings is progressively decreased.
