This Small Business Innovation Research Phase I project will develop particle measurement and control technologies for the thermal spray industry. Thermal spray is a rapidly growing element of the metals processing industry, which needs process control. Currently, there are no direct particle condition controls for lack of a sensor to provide real-time measurement of particle temperature and velocity. A short-exposure imaging spectrometer will be developed for measuring and controlling the particle temperature and velocity in thermal sprays. The innovation combines the technologies of imaging andspectroscopy to capture particle data, critical to the coating quality. The imaging field of view provides spatially resolved measurements in the direction across the particle stream. With the development of the sensor, the system to control the particle stream conditions in a thermal spray will then be developed. When particles are sprayed at optimized conditions over long production cycles, the coatings will be of the highestquality and exhibit excellent bond integrity, strength and density. Critical elements of the sensor will be modeled in a design study. Prototype hardware and software will be constructed and an experiment to examine feasibility of the particle measurement and control will be performed in an industrial thermal spray facility.Commercial Application The technology for measurement and control of particle conditions in thermal sprays has direct application to a wide range of manufacturing industries, autos, aerospace, energy and heavy equipment. Its use in the long production cycles, typical of these industries, will provide significant improvements in their productivity and competitiveness.

该小型企业创新研究第一阶段项目将为热喷涂行业开发颗粒测量和控制技术。 热喷涂是金属加工行业中一个快速发展的元素，需要过程控制。 目前，由于缺乏传感器来提供颗粒温度和速度的实时测量，因此没有直接的颗粒状态控制。 研制了一种短曝光成像光谱仪，用于测量和控制热喷涂中粒子的温度和速度。 该创新结合了成像和光谱技术来捕获颗粒数据，这对涂层质量至关重要。 成像视场提供在穿过粒子流的方向上的空间分辨测量。 随着传感器技术的发展，热喷涂中粒子流状态的控制系统也将随之发展。 当在长时间的生产周期内以优化的条件喷涂颗粒时，涂层将具有最高的质量并表现出优异的粘合完整性、强度和密度。 传感器的关键元件将在设计研究中建模。 将构建原型硬件和软件，并在工业热喷涂设备中进行实验，以检查粒子测量和控制的可行性。商业应用热喷涂中粒子状态的测量和控制技术可直接应用于制造业、汽车、航空航天、能源和重型设备等广泛领域。在这些行业典型的长生产周期中使用它将大大提高其生产力和竞争力。关键词热喷涂，成像光谱仪，测量，控制，颗粒
