The results show that the ingather of tungsten in the composites using internal feedstock injection is higher than that of the composites using external feedstock injection. For the composites using IFI method, the influence of input power on the copper oxidation is not evident, while more and more cuprite (Cu2O) is detected with the increasing of input power for the composites using EFI method. The thermal conductivity of WCu composite is lower than the theoretical value by ROM.

结果表明,在内部送粉条件下,复合材料中钨的收得率要高于外部送粉条件下复合材料中钨的收得率;在内部送粉条件下,功率对铜氧化的影响并不明显;而在外部送粉条件下,随着功率的提高,铜的氧化明显增多;由于氧化物和孔隙等的存在,利用大气等离子喷涂工艺制备的复合材料的导热率远远低于根据混合法则计算的理论值。

The results show that the decalescence of catalyst bed affects the process of hydrogen peroxide catalytic decomposition greatly. If the catalyst bed is preheated or made up of materials with low thermal conductivity, that influence can be depressed. At the same time, the response characteristic of catalyst bed and the efficiency of catalytic decomposition can be improved. The low frequency pressure instability of catalyst bed occurs because of the coupling of catalytic decomposition and supplying. The decomposition plane pushes all the way through the catalyst bed during pressure oscillations, causing unreacted liquid hydrogen peroxide to be exhausted from the bed and leading to the appearance of liquid hydrogen peroxide channeling. Consequently, how to prevent or at least limit this channeling is the key to eliminate the pressure instability of catalyst bed. It was found that adding clapboard to the catalyst bed can depress the pressure instability efficiently.

结果表明催化剂床及催化剂的吸热对过氧化氢分解过程影响很大,对催化剂床进行预热或采用热导率低的材料制造催化剂床等措施,可以降低催化剂床壁面吸热对催化分解过程的影响,提高催化剂床的响应特性和催化分解效率;催化剂床的低频不稳定是催化分解过程与供应系统耦合产生的,催化剂床气体界面的波动过程中,液体过氧化氢穿透催化剂床形成过氧化氢液体通道,过氧化氢液体通道的产生和扩大是催化剂床不稳定的主要原因,也是消除催化剂床不稳定的关键,试验中在催化剂床内加入分流板成功地抑制了催化剂床的低频不稳定。
