Ion cleaning technology has been widely used before coating deposition for its obviously contribution to improve coating properties. High energy cleaning source of Ar+ ions were produced by n merous e
High velocity air fuel technique has lower temperature than High velocity oxygen fuel technique during spray process. Moreover, the spray powders performs better oxidation resistance during HVAF spray
This study is to create a high density 8YSZ electrolyte of solid oxide fuel cell by the suspension flame spray. Dense zirconia coating couldnt be achieved by the normal flame spray due to its lower fl
在ABO3型铁电体钙钛矿材料(BiFeO3,Pb(Zr1-xTix)O3,BaTiO3)中已观察到光伏作用.但是O元素与过渡金属元素的电负性相差较大,使得ABO3型铁电体钙钛矿材料的禁带宽度较大(2.7-4 eV),较大的禁带宽度限制了其在太阳能电池方面的应用.KNbO3(KNO),作为一种重要的无铅型铁电材料,由于特殊的光学和电学材料,已经得到关注.研究表明采用BaNi1/2Nb1/2O3-δ(
Ultilizing diamond particles and fibers as fillers, diamond-silicone rubber composites are fabricated to obtain a thermally conductive and electrically insulating thermal interface materials and their
Ta涂层被认为是取代耐烧蚀涂用电镀Cr涂层的较佳候选涂层体系.本文利用电弧离子镀方法在钛合金表面制备了Ta-W涂层.研究了涂层/基体体系的显微结构及性能,以评估Ta-W涂层在钛合金表面的应用.涂层连续、均匀,主要由α-Ta(W)组成.涂层与基体晶格为共格/半共格,有助于涂层中α-Ta(W)的形成.涂层由100-250 nm致密等轴晶组成.划痕试验表明,涂层与基体的临界载荷达58.8N,可满足工程需
Polyurethane hybrid materials with different compositions of low surface energy polydimethylsiloxane and degradable poly(L-lactic acid)were synthesized by three major steps.Initially,the hydroxylation
Bimetallic composite pipe consists of a CRA layer for corrosion resistance and carbon steel for mechanical properties, which shows a promising prospect of gathering pipeline with its effective-cost an
With the increasingly severe working condition, machine components need to expose tocorrosive media including Cl- and SO42- containing environments. In this work, erosion-corrosion properties of HVOF
The respective advantages of porcine bone hydroxyapatite (PBHA) and chitosan (CS) were combinated together, Chinese medicine Drynariae Rhizoma (DR) was introduced into bone repair materials for the pu
