Acquisition of Scanning Electron and Optical Microscopes

本设备拨款提案的目的是通过购买一台配备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），使德雷塞尔大学（ME-DU）机械工程的显微镜设备现代化。该设备将取代ME-DU现有的相应老化仪器。该设备对大量研究项目非常重要，包括：{SYMBOL 183 \f " SYMBOL "}利用热喷涂（NSF）加工陶瓷聚合物纳米复合材料{SYMBOL 183 \f " SYMBOL "}用于轻量化结构（NSF）的等离子喷涂轻量化涂层{SYMBOL 183 \f " SYMBOL "}喷涂沉积（NSF）过程中微观结构的评价与控制{SYMBOL 183 \f " SYMBOL "}瞬态塑性相加工（NSF）制备的陶瓷-陶瓷复合材料的结构-加工-性能{SYMBOL 183 \f " SYMBOL "}喷雾的半固态加工铸造合金和复合材料（NSF） {SYMBOL 183 \f“SYMBOL”}激光拉曼光谱（NSF） {SYMBOL 183 \f“SYMBOL”}基于VLS反应的原位金属基复合材料（ONR） {SYMBOL 183 \f“SYMBOL”}建模和喷射铸造过程中的微结构发展（ONR） {SYMBOL 183 \f“SYMBOL”}多晶金属（NSF/ALOCOA）的再结晶和变形加工连续使用超过11年，基本上已经到了使用寿命的尽头。目前由ME-DU雇用的显微镜实验室的全职技术人员将负责维护机器处于良好的工作状态，培训学生使用仪器，并为偶尔的非专业用户驾驶仪器。技术人员由本提案的主要研究人员监督。根据新开发的Drexel课程，新的SEM机器也将像以前的SEM一样用于Drexel的高级设计项目和本科课程的教学，该课程强调实验室经验。

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.
