| در این پژوهش یک روش عددی مبتنی بر المان محدود به منظور شبیهسازی توزیع تنش در پوشش سد حرارتی معمولی و درجهبندی شده YSZ/ NiCrAlYپاشش پلاسمائی شده بر روی زیرلایه Hastelloy-x توسعه یافت.پوشش سدحرارتی معمولی و درجه بندی شده به روش پاشش پلاسمائی اعمال و مشخصهیابی پوششها با استفاده از مطالعات متالوگرافی توسط میکروسکوپ نوری و الکترونی روبشی انجام شد.نتایج شبیهسازی توزیع تنش حاکی از آن بود که در نمونه های شوک دیده تحت سیکل حرارتی فاقد زمان توقف در دمای تشکیل TGO، مقدار متوسط تنش ماکزیمم از 29 مگاپاسکال در سیستم دو لایه معمولی (فصل مشترک لایه روئی/لایه واسط) به 15/3 مگاپاسکال در سیستم درجه-بندی شده سه لایه (فصل مشترک 50% NiCrAlY- 50% YSZ / YSZ) و 1/8 مگاپاسکال در سیستم درجه بندی شده پنج لایه (فصل مشترک 25% NiCrAlY- 75% YSZ / YSZ) کاهش یافته و توزیع تنش در فصل مشترکها یکنواخت شده است که این امر به افزایش عمر سیستم سد حرارتی کمک میکند. | ||

| چکیده [English] | ||
| Thermal barrier coatings (TBCs) are one of the most conventionally- used protective materials which are employed as insulation media to save underlying metallic substrate from harmful effects at high temperature services In this study, a finite element-based numerical method was developed to simulate stress distribution in conventional and functionally graded thermal barrier coatings applied on the Hastelloy-x. Comparisons of simulation model results with experimental results of nano-indentation stress measurement method showed good agreement. The results of simulation showed that in samples after thermal shock without oxidation time (without Thermally Grown Oxide layer-TGO), the average value of the maximum stress is 29 MPa in duplex TBC (interface of top coat /boncoat), 3.15 MPa in three-layer FG-TBC system (interface of 50% NiCrAlY - 50% YSZ / YSZ) and 1.8 MPa in five-layer FG-TBC system (interface of 25% NiCrAlY- 75% YSZ / YSZ). Also, the stress distribution is more uniform in five-layer FG-TBC system that helps to increase the performance and extend the life time of thermal barrier system. | ||
