U.S.-Mexican Cooperative Research on Protective Coatings Applied by Pulsed Electrode Surfacing (PES)

9603039 Stiglich这一美洲计划奖将资助弗吉尼亚州材料修改公司的Jacob Stiglich博士和Cuernavaca自治大学的Ramiro Perez Campo博士之间的合作项目。他们将通过一种名为脉冲电极堆焊(PES)的发展中的MMI涂层程序，对应用于金属基材的涂层进行研究，以确定其在三种环境下的有效性--高应力磨损、腐蚀和氧化。MMI将制作实验涂层样品，UNAM的物理研究所将定义和进行环境暴露测试，并对样品进行初步表征，并将评估涂层承受测试环境的有效性。磨损问题存在于许多涉及机械和设备的工程应用中，但它们没有像腐蚀问题那样受到详细的关注。要解决磨损问题，首先必须确定导致失效的主要磨损机制。MMI认为，PES是一种重要的通用技术，不仅可以解决和缓解磨损，而且还可以解决腐蚀和高温氧化问题。***

9603039 Stiglich This Americas Program award will fund a collaborative project between Dr. Jacob Stiglich, Materials Modification, Inc. (MMI), Virginia, and Dr. Ramiro Perez Campo, Universidad Autonoma de Mejico (UNAM), Cuernavaca. They will conduct research on coatings applied to metallic substrates by a developmental MMI coating procedure called pulsed electrode surfacing (PES), in order to determine its effectiveness on three environments - high stress wear, corrosion, and oxidation. MMI will fabricate the experimental coated specimens and the Physics Institute in UNAM will define and conduct the environmental exposure testing and perform the primary characterization of specimens and will evaluate the effectiveness of the coatings to withstand the test environments. Wear problems exist in many engineering applications involving machinery and equipment, but they have not received the same detailed attention as corrosion problems. To solve wear problems it is first necessary to identify the predominant wear mechanisms that have contributed to failure. MMI believes that PES is an important, generic technology to address and alleviate not only wear, but corrosion and elevated temperature oxidation problems as well. ***
