| 中文摘要 | In this work, we reported a novel method that is flexible to metallize alumina ceramics with complex surface. Through Ti(2+) disproportionation occurred in molten NaCl-KCl-K(2)TiF(6) bath, the dense Ti layer was deposited on Al(2)O(3) ceramics surface with strong adhesion. The effects of reaction temperature, time and initial K(2)TiF(6) concentration on deposition rate were investigated. As-prepared coatings compose of bilayer structure of reactive Ti(2)O phase, namely, the outer layer with coarse grains and the inner layer with fine grains. The wettability of eutectic Ag72Cu28 and Pb37Sn63 alloys with metallized Al(2)O(3) ceramics was measured by using sessile drop method and compared with that of original ceramics. The results show that the metallized Al(2)O(3) surface could be reactively wetted well with Ag72Cu28 and Pb37Sn63 alloys. The contact angles lowered to 35 degrees and 8 degrees, respectively, when temperature rose to 900 degrees C, showing significant enhancement of wettability after Ti metallization by molten salt reaction.
