Quaternary Ammonium-based Composite Particles for Antibacterial Finishing of Cotton-based TextilesM.Messaoud1,P.Chaudouёt1,M.Langlet11. LMGP(Grenoble Institute of Technology-Minatec)摘 要:The antibacterial finishing of cotton-based fabrics has been achieved from quaternary ammonium-based composite particles.This functionalization is based on the simple......
prepared is an Al-rich composite coating. The Ti particles embedded in the Al matrix reacted with the Al particles and TiAl3 formed prior to other type of Ti-Al composite under this condition[15... Preparation of TiAl3-Al composite coating by cold spraying SHEN Li(沈 莉), KONG Ling-yan(孔令艳), XIONG Tian-ying(熊天英), DU Hao(杜 昊), LI Tie-fan(李铁藩) State Key Laboratory of Corrosion and Protection......
of La-Ti composite oxides) with a mass fraction of 1%-5% were added to the system. Then, the temperature of the system was increased to 120 ℃ to promote the formation of oligomer and the removal... by ZnO. It is becasue nanocrystals of La-Ti composite oxides can be dispersed homogenusously in the system and they did not precipitate from the solution. And every nanocrystasl can act as the boiling......
, the quantity of fractured particles on the fracture face decreases and the strength and ductility of the weld decrease. Key words: SiCp/LD2 composite; electron beam welding; interfacial reaction 1... possesses a very fine cellular solidification structure (3 to 4 mm apparent cell spacing) because of high cooling rate. Compared with the particles in the as-received composite, the surface of survived......

of TiAl to Ti3Al phase decreases correspondingly, the grains of the composites are remarkably refined, and the produced Al2O3 particles are uniformly dispersed. When 6% Nb2O5 is added, the composite has... above 800 ℃. Ceramic particles reinforced TiAl matrix composite is a promising material to cope with these problems. Especially, Al2O3 can be regarded as a good choice in virtue of its high elastic......
that Si3N4 particles in the composite are in cylindrical polyhedron shape. Extrusion deformation is beneficial to uniform distribution of Si3N4 particles and improves the relative density of Si3N4p/2024Al.... Fortunately, squeeze casting method is an effective method to fabricate composite when wettablity between matrix and reinforcement is poor, just as Si3N4 and Al system[8]. Generally, the application of ceramic......

bombardment by electron beam; (b) Under bombardment by electron beam for 10 s; (c) Under bombardment by electron beam for 20 s It can be seen from Fig.1 that the composite powders, such as particles... the repulsive force exceeded the biggest force that the composite needed to overcome, the migration appeared which confirmed there was polarization among the composite particles. Fig.1(a) shows the micro......
