納米粉體
Clear AFM images were(obtained) from PbZr_(0.90)Ti_(0.10)O_3-Fe_(0.003) nano powder sample prepared by DDS method. 采用DDS法制備PbZr0.
The chemically synthesized compound powder and the nano powder obtained by high-energy ball milling are two development trends of ZnO varistor c. 對(duì)粉體的制備方法和應(yīng)用前景進(jìn)行了展望,指出化學(xué)法合成復(fù)合粉體和高能球磨法制備納米粉體是氧化鋅壓敏陶瓷粉體的兩個(gè)主要發(fā)展趨勢(shì)。
The results indicate that the species and using level of dispersing agent were important factors to the particle size and distribution of the nano powder. 結(jié)果表明,分散劑的種類和用量是影響納米氧化鎂顆粒大小和均勻度的重要因素。
Based on all the above, feasibility of developing coated metallic nano powder materials by SLS was analyzed;at last an idea of prototyping metallic parts with coated metallic nano powder materials... 在此基礎(chǔ)上,分析了研究開(kāi)發(fā)選擇性激光燒結(jié)覆膜金屬納米粉末材料的可行性,并提出一種選擇性激光燒結(jié)覆膜金屬納米粉末材料成型金屬件的思路。
The micro or nano powder,or micro and nano powders were mixed into base oil,machinery oil 68,and confected into five kinds of running-in oils. 將微米和納米固體粉末單獨(dú)或混合加入到68%23機(jī)械油中,配制了5種微米、納米或微納米混合磨合油,并試驗(yàn)研究了5種磨合油分別應(yīng)用于鋼質(zhì)粗糙軟齒輪副間的磨合磨損行為和作用機(jī)制。
