Study on the Monitoring of Light Emission in Blasting Process

在喷砂过程中，可以观察到由于工件与喷砂介质之间的碰撞而产生的光发射。发光的强度和光谱取决于爆破条件。对爆破光辐射进行监测，有助于确定爆破条件，了解爆破状态。有必要构建传感器系统，玻璃将是传感器的合适材料。本研究的目的是实现光发射的监测。本研究利用氩离子激光照射硅溶胶-凝胶液体中的基板材料。不锈钢、硅、铟被用作衬底。结果表明，生长的针状玻璃柱具有高的长径比，生长速率与溶液温度和衬底材料有关。用聚硅氮烷代替溶胶-凝胶硅液，得到透明的玻璃薄膜。

In blasting process light emission due to the collision between workpiece and blasting media can be observed. The intensity and the spectrum of luminescence depend on the blasting conditions. To monitor the light emission will be useful to decide blasting conditions and understand the blasting state. It is necessary to build a sensor system and glass will be suitable material for a sensor. The aim of this research is to realize the monitoring of light emission. In this study, substrate materials were irradiated by argon ion laser beam in sol-gel silica liquid. Stainless steel, silicon, indium were used as substrates. As a result, needle-shaped glass pillars with high aspect ratio were obtained and the growing rate depended on the solution temperature and substrate materials. Also poly-silazane is examined instead of sol-gel silica liquid, and transparent glass film was obtained.
