Thermal plasma spraying is an important manufacturing technique that creates a thermal barrier coating to protect the surface underneath from wear, erosion, oxidation and corrosion. In this paper, we develop a new microstructure classification and quantification (MCQ) module that could fully automatically classify and quantify two types of microstructures, globular and interlamellar, in the top coat...
This paper presents an overview of space mission concepts for disrupting or pulverizing hazardous asteroids, especially with warning time shorter than approximately 10 years. An innovative mission concept, referred to as a nuclear hypervelocity asteroid intercept vehicle (HAIV) system, employs both a kinetic-energy impactor and nuclear explosive devices. A new mission concept of exploiting a multiple...
Thermal barrier coating, a widely used advanced manufacturing technique, provides thermal insulation and protection of a part surface from inclement environment. In the coating process, microstructures, such as globular and interlamellar, are naturally formed in the coating layer. The amount and types of microstructures greatly influences the property and quality of the coating. This paper introduces...
Thermal barrier coating is a widely used advanced manufacturing technique. This paper introduces an image analysis based automated thermal barrier coating porosity measurement (TBCPM) framework. The proposed automated image analysis framework consists of two modules, including 1) top coat layer detection module, and 2) microstructure recognition and porosity measurement module. The first module is...
Insulation systems for coils used in particle accelerator and associated magnets are selected to meet particular electrical and mechanical requirements. Voltage range from 6 volts to 10 kv to ground. Mechanical requirements vary with the size of the coil, magnetic forces, and the pressure required for mounting the coils on cores. In addition, many coils are exposed to radiation of various types and...
