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.

本小企业创新研究一期项目是对电极材料在大电流脉冲运行条件下的腐蚀性能进行研究。这项研究将延长一种新的脉冲灯的寿命，使其在经济上可行。这种新的灯可以成为紫外线(UV)水处理的行业标准，并实现一种新的光解剥漆工艺。脉冲功率电极材料的配方适用于低峰值电流下的连续或交流电流。初步研究表明，在脉冲大电流作用下，这些材料通过晶粒长大而降解，从而在晶界形成空洞。研究的目的是为了更好地了解材料性能对晶粒生长和侵蚀的影响，并展示增强和开发低侵蚀电极材料的可行性。该研究将提高对重复大电流脉冲循环电极材料退化和侵蚀的科学认识。此外，新的电极材料将扩大脉冲功率的使用，并提供一种替代硫化钨的方法，后者在欧洲是被禁止的，因为它具有放射性。主要目标是实现一种具有多种应用的新型商业脉冲灯。该灯是汞灯的潜在替代品，它将消除汞的使用和公众的暴露。该灯还将实现商业光解涂料的去除，取代劳动密集型的化学和研磨技术，产生灰尘和碎片，并产生有毒副产品。
