界面改性对SiCp/Cu复合材料导热性能的影响*(复合材料专题)

采用磁控溅射法结合结晶化热处理工艺在碳化硅（Silicon Carbide, SiC）颗粒表面成功制备了金属钼（Molybdenum, Mo）涂层,分析了Mo涂层的成分和形貌;然后采用热压烧结工艺制备了SiCp/Cu复合材料,重点对比分析了Mo界面阻挡层厚度对复合材料导热性能的影响。结果表明：磁控溅射法能够在SiC颗粒表面沉积得到Mo 涂层,随溅射时间的延长Mo涂层的厚度增加、粗糙度增大,且磁控溅射后SiC颗粒表面直接得到的Mo涂层为非晶态,结晶化热处理后,变为致密平整的晶态Mo涂层。磁控溅射时间即Mo涂层厚度对复合材料导热性能影响明显,随磁控溅射时间的增加,复合材料的热导率呈现先增后减趋势,采用磁控溅射9h镀Mo改性并经过800℃结晶化热处理的SiC复合粉体在850℃下热压烧结制备的SiCp/Cu复合材料（VSiC=50%）,其热导率达到了最高值274.056W/(m·K)。

PARLIAMENT AND DEFENCE OVERSIGHT

Abstract

A tremendous amount of important work has been done recently on operationalising the protection of civilians as a military task. The bulk of the discussion has focused on how militaries should respond to direct attacks on civilians. This is an important issue, but thinking about civilian protection should also include a serious examination of the ways in which the approach of military organisations to the problem of ‘spoiler’ groups can affect the level and dynamics of attacks on civilians – importantly, where armed groups are interested in violent control of civilian populations, attempts to ‘dislodge’ them from areas of control may substantially increase the level of violence against civilians (beyond the dangers to be expected from being near areas where active fighting is taking place). In 2009, the United Nations mission in the Democratic Republic of Congo (MONUC) supported the Congolese military in operations to dismantle the Hutu-dominated FDLR (Forces Démocratiques de Libération du Rwanda, Democratic Forces for the Liberation of Rwanda) militia group, at massive human cost. Critics have primarily focused on MONUC's failure to protect civilians from direct attack, consonant with the general discourse on tactics for civilian protection. These criticisms are valid, but in this paper I argue that two crucial additional considerations should be kept in mind: the way that military operations can affect violence against civilians, and the way that moralising the approach to armed groups, even those which have committed serious abuses, can limit military and political options – potentially in ways that increase civilian risk in the name of protecting them.
