“…In recent years, as some detectors should be operated under cryogenic temperature, the research on cryogenic magnetic shield has attracted lots of attentions. Masuzawa [1] measured the permeabilities of various shielding material at room temperature and at 4.2 K. Arpaia [2] experimentally studied the effect of temperature and mechanical strain on the magnetic properties of the Cryophy which was used for magnetic shielding surround superconducting radio frequency IOP Publishing doi:10.1088/1757-899X/1240/1/012037 2 cavities. In addition to the studies for materials, a few studies have been carried out to investigate the magnetic shielding for the application of very sensitive detectors.…”

A novel system which is specially designed for measuring effectiveness of small-scale magnetic shields in a liquid helium Dewar is introduced in this paper. This system is mainly applied to test the shielding performance of multilayer magnetic shielding structure which is used in the field of single-flux-quantum (SFQ) electronics testing at liquid helium temperature. This system allows using a fluxgate magnetometer to measure the magnetic flux instead of the superconducting quantum interference device (SQUID) method. The fluxgate magnetometer can be put into the system through a circular channel which is connected with the ambient environment. Thus, both the shielding effectiveness and the absolute magnetic flux can be obtained by this system. In addition, this system is designed with the shielding of the interference of environmental magnetic field, which improves the measurement accuracy. By utilizing this system, the magnetic shield effectiveness of a four-layer magnetic shields manufactured with low-temperature permalloy material and superconducting material was measured. The experimental results shows that the axial shielding effectiveness (SE) is 58.3 dB. The comparison between the experimental and theoretical results verified the effectiveness of this system.

“…The prevailing steel coatings include traditional coatings, superhydrophobic coatings, conducting polymer coatings and nanopolymer composite coatings. Traditional metal coatings have excellent mechanical properties, high resistance to corrosion and functional properties such as magnetostatic shielding and resistance to radiation [1][2][3][4]. However, their use is restricted due to shortcomings such as toxicity, high cost and short service life.…”

Corrosion is the principal reason for causing degradation of steel material properties, and coating is one of the most popular and effective ways to protect steel from corrosion. There are many kinds of coatings with different constituents, mechanisms and effectiveness. This paper presents a comprehensive review on the development of coating technology including traditional coatings, hydrophobic coatings, conducting polymer coatings and nanopolymer composite coatings. In particular, conducting polymers and nanopolymer composite coatings are reviewed in detail, which are the most popular and promising coatings. The advantages and limitations of each coating method as well as the influencing factors on corrosion protection are elaborated. Finally, the future research and applications are proposed.Coatings 2019, 9, 807 2 of 22 fluorocarbon coating, silicone coating, polyurethane coating and zinc-rich coating, provide corrosion protection by their barrier effect to ionic species, oxygen and water transport, which diminishes the corrosion rate [5][6][7], but their shortcomings are still significant, such as low impact strength, poor weatherability, poor bond strength and poor durability [8]. Almost all prevailing superhydrophobic coatings can adopt nanotechnology. Silica nanoparticles [9][10][11], carbon nanotubes [12,13], titanium oxide nanotubes [14][15][16][17], nanopolymers [18][19][20] and nanosilane [21][22][23] have been widely used for fabricating superhydrophobic coatings. Procedures such as the dip coating technique, electroless plating, sol-gel process and electro deposition are adopted to fabricate the superhydrophobic coatings. The water contact angles of the superhydrophobic coatings can reach 145-165 • C [9-23]. There is also some literature about using soft lithography method based on a polydimethylsiloxane (PDMS) template to prepare nanostructured superhydrophobic coatings [24,25]. Although significant progress has been achieved regarding the synthesis of superhydrophobic coatings and their anticorrosion properties for steel, the majority superhydrophobic coatings have been studied only in laboratory till now, and there are still many obstacles before they could be widely used in industry. The prevailing fabrications are complicated, costly and not suitable for on-site use. Many efforts should be made to develop an optimum superhydrophobic coating with excellent water repellency, long service life, good adhesion performance, low cost, easy fabrication and convenience in site spraying and curing.In recent years, conducting polymer coatings and nanopolymer composite coatings have been widely used in many projects. Many studies on nanopolymer composite coatings, conducting polymers and their combinations were conducted with a good deal of progress. Some new nontoxic corrosion protection materials with the properties of high efficiency and smart corrosion protection, long effective period and easy construction have been developed.Different coatings have deferent deposition mechanisms. At present, the prev...

A System Engineering Approach Using FMEA and Bayesian Network for Risk Analysis—A Case Study

et al. 2019

View full text Add to dashboard Cite

This paper uses a system engineering approach based on the Failure Mode and Effect Analysis (FMEA) methodology to do risk analysis of the power conditioner of a Proton Exchange Membrane Fuel Cell (PEMFC). Critical components with high risk, common cause failures and effects are identified for the power conditioner system as one of the crucial parts of the PEMFCs used for backup power applications in the telecommunication industry. The results of this paper indicate that the highest risk corresponds to three failure modes including high leakage current due to the substrate interface of the metal oxide semiconductor field effect transistor (MOSFET), current and electrolytic evaporation of capacitor, and thereby short circuit, loss of gate control, and increased leakage current due to gate oxide of the MOSFET. The MOSFETs, capacitors, chokes, and transformers are critical components of the power stage, which should be carefully considered in the development of the design production and implementation stage. Finally, Bayesian networks (BNs) are used to identify the most critical failure causes in the MOSFET and capacitor as they are classified from the FMEA as key items based on their Risk Priority Numbers (RPNs). As a result of BNs analyses, high temperature and overvoltage are distinguished as the most crucial failure causes. Consequently, it is recommended for designers to pay more attention to the design of MOSFETs’ failure due to high leakage current owing to substrate interface, which is caused by high temperature. The results are emphasizing design improvement in the material in order to be more resistant from high temperature.
