Improved corrosion resistance of Mg alloy AZ31B induced by selective evaporation of Mg using large pulsed electron beam irradiationWoo Jin Lee,Jisoo Kim,Hyung Wook Park摘 要:Large pulsed electron beam(LPEB) irradiation was employed as a surface treatment of magnesium(Mg)alloy AZ31B to enhance its corrosion and wear resistance. Selective evaporation of Mg......
[14]. Carbon nanotubes have extremely low electrical resistance which is derived from their 1D character and the peculiar electronic structure of graphite. Carbon nanotubes (CNTs) are the stiffest known... content for PLA/MWCNTs (a) and of surface resistivity and MWNTs content of for PLA/c-MWCNTs (b) Recordation of digital high resistance meter can be conversed to electrical conductivity to embody......
sintered above 2 200 ℃. The phase composition and microstructure of the RSiC-WC composites ceramics were investigated by XRD, SEM and EDS. The open porosity, flexural strength and electrical resistivity were... between SiC grains and well wet with SiC grains. The lowest open porosity, the highest flexural strength and the lowest electrical resistivity of the RSiC-WC composite ceramics are 19.2%, 109 MPa......
produced by the electrical explosion of zirconium (Zr) wires, and blended with platinum (Pt) powders (<44 mm) for 2-72 h in ambient atmosphere. The Pt particle size followed the typical decreasing...; electrical wire explosion; mechanical alloying 1 Introduction Platinum (Pt) and platinum group metals are highly valuable because only a few hundred tons are produced annually. In spite......
