该小型企业创新研究（SBIR）第二阶段项目将进一步研究高电流脉冲操作下电极材料的侵蚀特性，并证明新脉冲灯的寿命延长，使其具有经济实用性。随着使用寿命的延长，新灯可以成为紫外线水处理的行业标准，并实现新的光解油漆剥离工艺。用于脉冲功率电极的材料最初被配制用于低峰值电流下的连续或交流电流。在第一阶段中，钨复合材料用特定的工艺制造，腐蚀的十六分之一的标准电极材料的侵蚀。第二阶段继续对这种钨复合材料及其制造工艺进行研究，以证明低腐蚀性，目的是证明延长灯的寿命，满足商业化的要求。如果成功，拟议的研究将提高电极材料在重复高电流脉冲循环下的侵蚀的科学理解。新的电极材料将扩大脉冲功率的使用，并提供更好的替代品，钍钨，这是禁止在欧洲，因为它的放射性。主要目标是实现新的商业脉冲灯。这种灯将取代汞灯，减少汞的使用和公众的汞暴露。该灯还将实现商业光解油漆去除，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。光解过程将提供一种成本更低、更清洁的去除含铅油漆的方法。这将使减排取代目前流行的“临时措施”，并支持消除儿童铅中毒的国家目标。新灯的商业市场包括所有紫外线水处理和广泛的油漆去除应用。

This Small Business Innovation Research (SBIR) Phase II project is to conduct further research on the erosion properties of electrode materials under high-current pulsed operation, and demonstrate extended lifetime for a new pulsed lamp, making it economically practical. With increased lifetime, the new lamp can become the industry standard for UV water treatment and enable a new photolytic paint stripping process. Materials used for pulsed power electrodes were originally formulated for continuous or alternating current at low peak current. In Phase I a tungsten composite fabricated with a specific process eroded at one-sixteenth of the erosion of the standard electrode material. Phase II continues the research on this tungsten composite and its fabrication processes to demonstrate low erosion, with the objective of demonstrating increased lamp life that meets requirements for commercialization. If successful the proposed research will enhance scientific understanding of the erosion of electrode materials under repeated high-current pulsed cycling. New electrode materials will expand the use of pulsed power and provide better alternatives to thoriated tungsten, which is banned in Europe because of its radioactivity. The primary goal is to enable a new commercial pulsed lamp. The lamp will replace mercury lamps, reducing 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. The photolytic process will provide a lower cost and cleaner method of removing lead paint. This will allow abatement to replace "interim measures" currently in vogue, and support national goals to eliminate childhood lead poisoning. The commercial market for the new lamp encompasses all of UV water treatment and a wide range of paint removal applications.
