This Small Business Innovation Research (SBIR) Phase I project will address in-situ forming of environmentally protective coatings over engineering material surfaces subject to degradation. Most failures of large scale engineering systems result from the progressive environmental degradation of metallic components over time. Due to operational and cost constraints, timely repair or restoration is not feasible, and premature failures of these systems result in loss of productivity and wasted materials. Phase I will develop a low cost thermal process for engineering materials to combat corrosion-related problems. Material designs and processing criteria will be examined in dry and wet conditions in order to evaluate resultant coatings for high-temperature oxidative and hydrogen environment applications. Phase I will demonstrate basic concepts for material compatibility and key process parameters that could lead to desired coating quality and resistance to oxidation and corrosion. Phase II would proceed to process and material optimization. If successful, this process will provide a significant cost reduction for restoration or modification of engineering material surfaces leading to an extension of the usefulness or life of manufactured systems. The process is specifically adaptable to on-site surfaces that are inaccessible to conventional surface treatments, such as plating, laser cladding, or plasma spraying. It would also be commercially useful in forming durable surface layers since a genuine alloying of the electrode material to substrate occurs.

这个小型企业创新研究(SBIR)第一阶段项目将解决在易降解的工程材料表面原位形成环保涂层的问题。大型工程系统的大多数故障是由于金属部件随着时间的推移而逐渐恶化的环境造成的。由于操作和成本的限制，及时维修或恢复是不可行的，这些系统过早故障会导致生产力损失和材料浪费。第一阶段将为工程材料开发一种低成本的热工艺，以应对与腐蚀相关的问题。将在干燥和潮湿条件下检查材料设计和工艺标准，以评估高温氧化和氢气环境应用所得到的涂层。第一阶段将演示材料兼容性的基本概念和关键工艺参数，这些参数可能会导致所需的涂层质量和抗氧化性和耐腐蚀性。第二阶段将继续进行工艺和材料优化。如果成功，这一过程将显著降低修复或修改工程材料表面的成本，从而延长制造系统的可用性或寿命。该工艺特别适用于传统表面处理无法达到的现场表面处理，如电镀、激光熔覆或等离子喷涂。由于电极材料与基材发生真正的合金化，因此在形成耐用的表面层方面，它在商业上也是有用的。
