WebAug 25, 2024 · They pointed out Cu wetting on C/C composites was improved and direct joining of C/C composites to Cu was feasible without any filler metal, and the best results in terms of wettability of molten copper on C/C have been achieved by modifying C/C composites with Cr. ... The graphite with porosity of about 15 vol% was supplied by Dong … WebJan 3, 2024 · Abstract. The paper studies the wetting of grain boundary triple junctions (GB TJs) by the second solid phase (intermetallic) δ in the Cu–In alloys. In this system, the portion of grain boundaries in a copper-based solid solution (Cu), which are "wetted" by the second solid phase δ, changes non-monotonically with increasing temperature.

WebMar 26, 2024 · CO 2 wetting on Cu-like substrates. (a) Wetting morphologies of a CO 2 droplet on a smooth Cu-like surface with the interaction energy parameter between CO 2 and the Cu-like surface varying from 0.005–0.012 eV. (b) The total potential energies develop with MD simulation times in the CO 2 /Cu-like surface systems. WebDec 12, 2013 · The Cu/Co(W) interface exhibited greater adhesion strength than the Cu/Ta interface, which may be due to the smaller lattice mismatch (2.8% between Cu and Co, compared with 22.0% between Cu and Ta). Cu on pure Co also exhibited lower wetting angle (60°), and thereby greater adhesion strength than the Cu/Ta, which is consistent … WebJan 1, 2009 · The median downstream EM lifetimes at 300C for PVD Ta(N) Liners ranged from 15 hours (Cu seed / Co cap) to 40 hours (CuMn seed, No Co cap), consistent with earlier studies [2][3][4] [5] [6].
