    • A multi-layer coating for protection of metals and alloys against oxidation at high temperatures in general is provided. The invention utilizes a multi-layer ceramic coating on metals or alloys for increased oxidation-resistance, comprising at least two layers, wherein the first layer (3) which faces the metal containing surface and the second layer facing the surrounding atmosphere (4) both comprise an oxide, and wherein the first layer (3) has a tracer diffusion coefficient for cations M m+ , where M is the scale forming element of the alloy, and the second layer (4) has a tracer diffusion coefficient for oxygen ions O 2- satisfying the following formula: wherein p(O 2 ) in is the oxygen partial pressure in equilibrium between the metallic sub-strate and M a O b , p(O 2 ) ex is the oxygen partial pressure in the reaction atmosphere, D M is the tracer diffusion coefficient of the metal cations M m+ in the first layer (3), and D O is O 2- tracer diffusion coefficient in the second layer (4). The coating may be used in high temperature devices, particularly for coating intercon- nect materials in solid oxide electrolytic devices, including solid oxide fuel cells (SOFCs) and solid oxide electrolysis cells (SOECs).
    • 提供了用于在高温下保护金属和合金免受氧化的多层涂层。 本发明利用金属或合金上的多层陶瓷涂层来提高抗氧化性,包括至少两层,其中面对金属容纳表面的第一层(3)和面向周围大气的第二层(4)都是 包括氧化物,并且其中所述第一层(3)具有用于阳离子M m + +的示踪剂扩散系数,其中M是所述合金的氧化皮形成元素,并且所述第二层(4)具有示踪剂 满足下列公式的氧离子O 2的扩散系数:其中中的p(O 2 2 N)是氧分压之间的平衡中的氧分压 金属子化合物和M a O b B,其中p(O 2 2)3以上的氧分压是 反应气氛D M是第一层(3)中金属阳离子M + m + +的示踪剂扩散系数,D O O是 在第二层(4)中的示踪剂扩散系数O 2。 该涂层可用于高温装置,特别是用于在固体氧化物电解装置(包括固体氧化物燃料电池(SOFC))和固体氧化物电解槽(SOEC)中涂覆相互连接的材料。

    • A screwing device, which serves for screwing boards (2) onto underlying crossbeams (3) in such a way that the screws are screwed tilted in from the edges (5) of the boards (2), comprises a base (7) with an oblong foot (8) which in use stands on the upper side of the boards (2), two arms (9) extending tilted out from each their end of the foot (8), and two opposite screw drivers (10), which are mounted on each their arm (9) and each is arranged with means for conveying a disposable belt (34) of releasable screws (6) and for stepwise screwing in screws (6) from the belt (34). The components of a terrace can by means of the screwing device be screwed faster together than hitherto known, and at the same time the terrace obtains optimal strength.
    • 一种螺丝装置,其用于将板(2)拧到下面的横梁(3)上,使得螺钉从板(2)的边缘(5)旋入螺钉中,包括基座(7),其具有 长方形脚(8),其在使用中位于板(2)的上侧,从其每个端部(8)倾斜出的两个臂(9)和两个相对的螺钉驱动器(10) 安装在其每个臂(9)上,并且每个臂布置有用于输送可释放螺钉(6)的一次性带(34)的装置,并且用于从带(34)逐步拧入螺钉(6)。 通过螺丝装置的平台的部件可以比迄今已知的更快地拧紧,同时露台获得最佳的强度。
