Acquisition of Scanning Electron and Optical Microscopes

摘要CTS-9414035 Roger Doherty 该设备赠款提案的目的是通过购买配备EDS X射线探测器及其微分析处理器的分析扫描电子显微镜（SEM），使德雷克塞尔大学（ME-DU）机械工程的显微镜设施现代化。 这一设备将取代地中海-贫铀所现有的相应的老化仪器，这一设备对许多研究项目都很重要，其中包括：{SYMBOL 183 \f“Symbol”}使用热喷涂（NSF）加工陶瓷聚合物纳米复合材料{SYMBOL 183 \f“Symbol”}用于轻质结构的等离子喷涂轻质涂层（NSF）{喷射沉积（NSF）过程中陶瓷-陶瓷复合材料的微观结构评估和控制{SYMBOL 183 \f“Symbol”}结构-加工-性能 瞬态塑性相加工（NSF）{SYMBOL 183 \f“Symbol”}喷射铸造合金和复合材料的半固态加工（NSF）{SYMBOL 183 \f“Symbol”}使用激光研究失效单向复合材料的微观力学 拉曼光谱（NSF）{SYMBOL 183 \f“Symbol”}通过VLS反应原位金属基复合材料（ONR）{SYMBOL 183 \f“Symbol”}喷射铸造（ONR）过程中的建模和微观结构发展{SYMBOL 183 \f“Symbol”}多晶金属的再结晶和变形处理（NSF/ALOCOA） 目前可用的SEM已连续使用超过11年，基本上已达到其使用寿命。 负责维护机器在良好的工作条件，培训学生在其使用和驾驶仪器偶尔非专家用户，将分配给全职技术员目前雇用的ME-DU的显微镜实验室。 技术人员由本提案的主要调查人员监督。 新的SEM机器也将被用于，因为是以前的SEM，在高级设计项目和教学的本科课程在德雷克塞尔在新开发的德雷克塞尔课程，重点是实验室的经验。

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.
