Acquisition of Scanning Electron and Optical Microscopes

CTS-9414035罗杰·多尔蒂这项设备赠款提案的目的是通过获得一台配备能谱X射线探测器及其微分析处理器的分析扫描电子显微镜，使德雷克塞尔大学机械工程(ME-DU)的显微镜设施现代化。该设备将取代ME-DU目前可用的相应老化仪器。这种设备对于大量的研究项目来说是重要的，包括：{符号183\f“符号”}热喷涂陶瓷聚合物纳米复合材料{符号183\f“符号”}等离子喷涂轻质结构涂层{符号183\f“符号”}喷射沉积(NSF)过程中微观组织的评价和控制{符号183\f“符号”}瞬时塑性相处理(NSF)陶瓷-陶瓷复合材料的结构-加工-性能{符号183\f“符号”}喷射铸造合金的半固态处理和复合材料(NSF){SYMBOL 183\f“SYMBOL”}利用激光拉曼光谱(NSF)研究单向复合材料失效的细观力学{SYMBOL 183\f“SYMBOL”}喷射铸造(ONR)原位金属基复合材料{SYMBOL 183\f“SYMBOL”}喷射铸造(ONR){SYMBOL 183\f“SYMBOL”}多晶金属的再结晶和变形加工(NSF/ALOCOA)目前可用的扫描电子显微镜已连续使用11年以上，基本上已接近使用寿命。ME-DU目前雇用的显微镜实验室的全职技术员将负责维护机器在良好的工作条件下，培训学生使用它，并为偶尔的非专家用户操作仪器。技术人员由这项提案的主要调查人员监督。新的扫描电子显微镜机器和以前的扫描电子显微镜一样，也将用于德雷克塞尔大学的高级设计项目和本科课程的教学，因为新开发的德雷克塞尔课程侧重于实验室经验。

ABSTRACT CTS-9414035 Roger Doherty The purpose of this equipment grant proposal is to modernize the microscopy facility of the Mechanical Engineering at Drexel University (ME-DU) by acquiring an analytical scanning electron microscope (SEM) equipped with an EDS X-ray detector and its microanalytical processor. This equipment will substitute the corresponding aging instruments that are currently available at ME-DU. This equipment is important for a large number of research projects, including the following: {SYMBOL 183 \f "Symbol"} Processing of Ceramic Polymer Nanocomposites Using Thermal spray (NSF) {SYMBOL 183 \f "Symbol"} Plasma Sprayed Lightweight Coating for Lightweight Structure (NSF) {SYMBOL 183 \f "Symbol"} Evaluation and Control of Microstructure During Spray Deposition (NSF) {SYMBOL 183 \f "Symbol"} Structure-Processing-Properties in Ceramic-Ceramic Composites Manufactured by Transient Plastic Phase Processing (NSF) {SYMBOL 183 \f "Symbol"} Semisolid Processing of Spray Cast Alloys and Composites (NSF) {SYMBOL 183 \f "Symbol"} Investigation of the Micromechanics of Failure Unidirectional Composites Using Laser Raman Spectroscopy (NSF) {SYMBOL 183 \f "Symbol"} In-Situ Metal Matrix Composites Via VLS Reactions (ONR) {SYMBOL 183 \f "Symbol"} Modeling and Microstructural Development During Spray casting (ONR) {SYMBOL 183 \f "Symbol"} Recrystalization and Deformation Processing of Polycrystalline Metals (NSF/ALOCOA) The currently available SEM has been continuously used for over 11 years and is essentially at the end of its useful life. The responsibility of maintaining the machine in good working condition, training students in its use and driving the instrument for occasional non-expert users, will be assigned to the full-time technician currently employed by the ME-DU for the microscopy laboratory. The technician is overseen by the principle investigators of this proposal. The new SEM machine will also be used, as was the previous SEM, in t he senior design projects and teaching of undergraduate courses at Drexel in light of the newly developed Drexel Curriculum which has an emphasis on the laboratory experience.
