چکیده

پوشش­های شیشه-سرامیک آپاتیت-آنورتیت توسط غوطه­وری زیرلایه Ti-6Al-4V در سل هایی با مقادیر مناسب به صورت تک لایه و دو لایه، تهیه گردیدند. سپس تا دمای 800 درجه سانتیگراد تحت عملیات حرارتی قرار گرفتند. از آنالیز پراش اشعه ایکس و آنالیز حرارتی تفاضلی، به ترتیب جهت تعیین ترکیبات تشکیل شده و بررسی تحولات صورت گرفته استفاده گردید. سختی و زبری پوشش­ها، نیز به ترتیب توسط دستگاه میکرو­سختی و آنالیز میکروسکوپ نیروی اتمی، انجام گرفت. میکروسکوپ الکترونی روبشی نیز یکنواختی و چسبندگی پوشش­های تک لایه را نشان می دهند. نتایج نشان دادند که پوشش­های دو لایه دارای سختی بیش­تری نسبت به پوشش­های تک لایه می باشند. زبری تمامی پوشش­ها در محدوده مناسب جهت کاربردهای دندانی می باشد.
