SBIR Phase I: Development of a New High Intensity Pulsed Light Source System

这个小企业创新研究一期项目是对电极材料在大电流脉冲操作下的侵蚀性能进行研究。这项研究将延长新型脉冲灯的使用寿命，使其经济实用。新灯可以成为紫外线（UV）水处理的行业标准，并实现新的光解漆剥离工艺。用于脉冲功率电极的材料是在低峰值电流下为连续或交流电流配制的。初步研究表明，在脉冲大电流作用下，这些材料通过晶粒生长降解，导致晶界处形成空洞。研究目的是为了更好地了解材料性能如何影响晶粒生长和侵蚀，并展示增强和开发低侵蚀电极材料的可行性。提出的研究将加强对电极材料的降解和侵蚀的科学理解，这些材料经过反复的大电流脉冲循环。此外，新的电极材料将扩大脉冲功率的使用，并提供一种替代碳化钨的材料，碳化钨因其放射性在欧洲被禁止使用。主要目标是使一种新的商业脉冲灯具有多种应用。这种灯是汞灯的潜在替代品，它将消除汞的使用和公众接触。这种灯还将实现商业化的光解涂料去除，取代化学和研磨技术，这些技术是劳动密集型的，会产生灰尘和碎片，并产生有毒的副产品。

This Small Business Innovation Research Phase I project is to conduct research on the erosion properties of electrode materials under high-current pulsed operation. This research will allow extended lifetime for a new pulsed lamp, making it economically practical. The new lamp can become the industry standard for Ultra-Violet (UV) water treatment and enable a new photolytic paint stripping process. Materials used for pulsed power electrodes were formulated for continuous or alternating current at low peak current. Under pulsed high current, preliminary research shows that these materials degrade through grain growth, leading to void formation at the grain boundary. The research objective is to develop a better understanding of how material properties affect grain growth and erosion, and show the feasibility of enhancing and developing low erosion electrode materials.The proposed research will enhance scientific understanding of the degradation and erosion of electrode materials that undergo repeated high-current pulsed cycling. Also, new electrode materials will enable the expanded use of pulsed power and provide an alternative to thoriated tungsten, which is banned in Europe because of its radioactivity. The primary goal is to enable a new commercial pulsed lamp with many applications. The lamp is a potential replacement for mercury lamps, which would eliminate mercury use and exposure of the public. The lamp also will enable commercial photolytic paint removal, replacing chemical and abrasive techniques that are labor intensive, create dust and debris, and generate toxic byproducts.
