چکیده

در این پژوهش به بررسی پارامترهای مؤثر بر اکسیداسیون سرامیک دی بوراید زیرکونیوم پرداخته می‌شود. دما، زمان و فشار به همراه افزودنی‌های مختلف (SiC, Cf, MoSi2, HfB2  ZrC) مورد بررسی قرار گرفتند. طراحی آزمایش به روش تاگوچی انجام شد. فرآیند اکسیداسیون در دمای 1600 درجۀ سانتی‌گراد در کوره باکسی به مدّت یک ساعت انجام شد. مشخص شد که HfB2 سبب بهبود مقاومت به اکسیداسیون می‌شود. نتیجه‌گیری شد که با افزایش میزان ZrC، مقاومت به اکسیداسیون کاهش می‌یابد. SiC با تشکیل لایه بروسیلیکاتی سبب بهبود مقاومت به اکسیداسیون می‌شود. در میان پارامترهای SPS، دما مؤثرترین پارامتر بود

چکیده [English]

In this research, the effective parameters on the oxidation of ZrB2 ceramics were investigated. Temperature, time and pressure in addition of different additives (SiC, Cf, MoSi2, HfB2 and ZrC) were investigated. Taguchi method was applied for experimental design. Oxidation test was conducted on box furnace at 1600 C for one hour. It was cleared that the HfB2 resulted to better oxidation resistance. At the presence of ZrC, oxidation resistance was damaged. SiC improves the oxidation resistance by borosilicate layer formation. Finally, among the SPS parameters, temperature is the most.
