In this paper , 6013al / sicp / gr metal matrix composite ( mmc ) was produced by spray codeposition , by means of changing the medium of quenching , influence of five types of heat treatment system ( furnace cooling , air cooling , water quenching , dry ice quenching , liquid nitrogen quenching ) and different aging temperature on the damping was studied systematically 本文采用噴射共沉積方法制備了6013al sicp gr金屬基復合材料( mmc ) ，通過改變淬火介質，較為系統地研究了五種熱處理制度(爐冷、空冷、水冷、干冰冷及液氮冷)以及不同時效溫度( 120 、 150 、 170 、 190及210 )對6013al sicp grmmc阻尼性能影響。
That is the premise of the bg / ha electrophoresis codeposition . the laws of the electrophoresis deposition of the bg and ha partic les were found by the study on each of their deposition under the different conditions . the electrophoresis codeposition of the bg and ha particles had been studied and the bg / ha graded coating , which is compact in the bottom layer and porous near the surface layer , had been prepared on the surface of the dental implant after the low temperature heat treatment ( about 740 ) and fast firing ( 50 - 80 / min , heat preservation time was 5 - 8min . ) 以bg微粉和ha微粉作為涂層原料，通過研究bg和ha微粉在非水介質中的分散情況和帶電特性，選擇冰醋酸為介質，使分散在其中的bg顆粒和ha顆粒表面均帶上正電荷，為電泳共沉積提供前提條件；通過對不同條件下bg 、 ha各自電泳沉積的研究，探索出了兩者電泳沉積的規律；通過對bg和ha在冰醋酸中電泳共沉積以及后續低溫( 740左右)快燒( 50 ? 80 min ，保溫5 ? 8min )熱處理的研究，在鈦合金牙根種植體基體上成功制備出了底層致密而表層多孔的bg ha梯度涂層。
In this thesis , in order to reducing the amount of the pt catalyst , improving the electrocatalytic activity of the pt catalysts and utilization ratio of pt , the electrochemical codeposition method by cyclic voltammetry ( cv ) was used to prepare a series pt / moox / glassy carbon ( gc ) composite electrodes with high dispersibility . the composite electrode , pt / moox / gc , was characterized to study its composition and its electro chemical behavior by cv . using the xrd and sem techniques , the size and the dispersion degree of the catalyst particles were studied in presence or absence of moox in the catalyst 為了降低主催化劑pt的用量、提高pt的活性和利用率，本論文利用循環伏安法共沉積制備高分散的pt moo _ x催化劑顆粒，利用循環伏安電化學表征、 xrd和sem技術研究了引入moo _ x后的催化劑即pt moo _ x顆粒的粒子大小、分散狀態；利用icp - aes定量分析pt moo _ x催化劑顆粒的組成含量；并借助于電化學方法分別評價了pt moo _ x gc電極催化劑的對甲醇的電催化活性和穩定性、氧還原電催化活性。
Deposition mechanism of electroless plating tin in acid chloride solutions was analyzed theoretically , and three steps were summed up , including period of replacement reaction , coexistence periods of copper - tin codeposition and self - catalyzed deposition , and period of self - catalyzed deposition 從理論上系統地分析了酸性氯化物化學鍍錫的沉積機理，將其歸納為置換反應期、銅錫共沉積與自催化沉積共存期和自催化沉積期三個階段。
Presence of vulcan xc - 72 active carbon powder in the pt / moox / gc composite electrode by electrochemical codeposition made peak potential of methanol oxidation a further negative shift of about 50mv and a further promotion of co - tolerant performance for methanol oxidation 催化劑中vulcanxc - 72活性碳粉的引入即共沉積制備的pt moo _ x c gc電極催化劑甲醇氧化峰電位又進一步負移50mv左右，抗co中毒催化性能又進一步提高。
