The resistance welding method of different kinds of materials is the method for welding an iron material and an aluminum alloy material, and comprises the steps of: performing in advance a coating treatment at least to a portion of the aluminum alloy material, where resistance welding is ...
Comparison of the Effect of Different Cavity Designs and Temporary Restoration Materials on the Fracture Resistance of Upper Premolars, Undergone Re-treatm... Due to the increasing variety of temporary restorative materials and the importance of the remaining crown structure in maintaining the fracture ...
PROBLEM TO BE SOLVED: To provide a resistance welding method for different kinds of materials, a method that can use existing welding equipment, that is excellent in continuous spot welding, and that can reduce maintenance frequency of an electrode, and also to provide a resistance welding member...
aIt was confirmed for different materials and electrodes that there is a similar positive effect of nano fillers on PD resistance 它为不同的材料和电极被证实了有nano补白的一个相似的正面作用在PD抵抗[translate]
[29], [30] investigated the relationships between the properties and RGD resistance of NBR materials featuring different crosslink systems using mixture gas with N2 and CO2. They reported that NBR materials cured using a conventional vulcanization (CV) system, resulting in a high crosslink density...
The trenched gate further includes at least two mutually insulated trench-filling segments each filled with materials of different work functions. In an exemplary embodiment, the trenched gate includes a polysilicon segment at a bottom portion of the trenched gate and a metal segment at a top ...
aThere are a variety of materials used as electrodes in electrolysers.Each metal has a different level of activity, electrical resistance,resistivity against corrosion and life time. 有用于各种各样的材料作为电极在electrolysers。每种金属有活动、电阻、抵抗力反对腐蚀和生活时间的一个不同的水平。[trans...
In series II five groups of three unit bridges (n =5/group; codes A to E) were prepared from Artglass dental composite without (group A) or with (groups B to E) different Connect fiber reinforcement locations/techniques. Bridges were cemented using 2 bond resin cement to a standardized ...
The oxidation behaviour of the phase in Nd-Fe-B sintered magnets containing additional elements (Al, Co, V, Nb, Mo) was investigated by Mssbauer spectrometry. The microstructure of the different samples was first characterized. Added elements were detected in both intergranular and intragranular pre...
This chapter presents a broad overview of negative differential resistance (NDR) devices and their operation, including intraband and interband tunneling topologies. The materials science issues and tradeoffs considered for their synthesis as well as how each impacts overall NDR performance are also discu...
