We produced Y Ba2Cu3O7−x ceramic and deposited it in AISI 316L steel in order to develop a superconducting fault current limiter device. The objective of this work is to evaluate the influence of heat treatments on the YBCO/316L junction. We produce a polycrystalline ceramic through solid state reaction. We used Y2O3, BaCO3 e CuO as reagents, which were mixed and macerated before calcination and sintering. The heat treatment of calcination and sintering were both performed at 930◦C for 12h followed by slow cooling. Both treatments took place under oxygen flow. We cut 3mm thick AISI 316L steel plates into small 10mm x 75mm devices. These devices went through a milling process in which a 3mm x 50mm x 1mm groove was created on their surface. At first, we made a preliminary deposition of YBCO on the groove of the AISI 316L device. We then filled two metal samples with YBCO and compressed the powders inside it by using a hydraulic press. The samples remained at 1040◦C (A1040) and 950◦C (A950) for 20min and were slowly cooled to room temperature. Sample A1040 showed severe structural deterioration, evidencing the non-adhesion of the superconductor in its inside. Sample A950 showed structural integrity. We characterize the YBCO produced and the samples deposited through XRD, SEM and EDS. The results show the existence of spurious components in the material though the average grain boundary size reduced significantly.
制备了yba2cu3o7−x陶瓷，并将其沉积在aisi316l钢上，用于超导故障限流装置的研制。本工作的目的是评估热处理对YBCO/316L结的影响。我们通过固相反应生产了一种多晶陶瓷。以Y2O3、BaCO3、CuO为原料，混合浸渍后再煅烧烧结。煅烧和烧结的热处理均在930℃下进行12h，然后缓慢冷却。两种治疗都是在氧气流下进行的。我们将3mm厚的AISI 316L钢板切割成10mm × 75mm的小装置。这些设备经过铣削过程，在其表面上形成3mm x 50mm x 1mm的凹槽。首先，我们在aisi316l器件的凹槽上进行了YBCO的初步沉积。然后我们用YBCO填充两个金属样品，并使用液压机压缩其中的粉末。样品在1040°C (A1040)和950°C (A950)下保持20分钟，缓慢冷却至室温。样品A1040表现出严重的结构劣化，证明其内部的超导体没有粘附。样品A950结构完整。通过XRD、SEM和EDS对制备的YBCO和沉积的样品进行了表征。结果表明，虽然材料的平均晶界尺寸明显减小，但材料中仍存在虚假成分。
