Abstract: A device for measuring surface-temperature of a turbine blade, the device including a probe having a front-end mirror for receiving infrared radiation of a surface on the blade, a collimation lens for refracted the infrared radiation, a PD detector to receive the infrared radiation, and a focal-length servo; and a radial-scanning servo connected to the probe. The front-end mirror, the collimation lens, and PD detector are disposed along the optical axis of the collimation lens. The focal-length servo is adapted to move the collimation lens along the optical axis of the collimation lens. The radial-scanning servo is adapted to move the probe along the optical axis of the collimation lens. The device of the invention is capable of accurately targeting a particular point on the blade having an irregular shape for temperature measurement to accurately detect the temperature distribution on the surface of the blade.

Abstract: A method for preparing a supercapacitor electrode material Ni doped CoP3/Ni foam is provided, and the CoP3 is applied to the supercapacitor for the first time. The method belongs to a technical field of synthesis and preparation of supercapacitor materials. The present invention adopts a low-temperature phosphating process to prepare the Ni-doped CoP3/foamed nickel as the electrode material of the supercapacitor, so as to provide advantages such as simple synthesis process, easy control, low cost and high specific capacity. The supercapacitor electrode material Ni doped CoP3/Ni foam prepared by the present invention has a hierarchical structure and a large specific surface area, which is beneficial to shorten an ion transmission path, reduce an interface resistance between the electrode material and electrolyte, provide more active sites, and provide a higher specific capacity in alkaline electrolyte. The electrode material shows great potential in electrochemical energy storage.

Abstract: The present invention discloses CrN thermoelectric material and its preparation method, which belongs to the field of thermoelectric materials. Here, we provide a study for thermoelectric properties, hardness, wear-resisting performance and thermal stability of CrN. These results show that CrN possesses excellent mechanical properties and thermal stability. The hardness of the bulk CrN sample is as high as 735.76 HV, which is far superior to most of thermoelectric materials. The thermogravimetric analysis test indicates that CrN remain stable at 873 K. Friction and wear test results demonstrate that the low friction coefficient (˜0.42) and good wear resistance of CrN. The maximum ZT value of 0.104 is observed at 848 K. In this way, CrN may be a promising thermoelectric material in extreme environment application which requires both mechanical and thermoelectric properties. Such as collision avoidance systems and outerspace.
