U.S.-Mexico Cooperative Research on Protective Coatings Applied to Steel Substrates

Stiglich 9815044美国-墨西哥奖由土木和机械工程部，设计，制造和工业创新部以及国际项目部共同资助，将为Jacob J. Stiglich博士，材料改性公司之间的合作研究项目提供支持。(MMI)和墨西哥库埃尔纳瓦卡的墨西哥国立自治大学物理研究所的Ramiro Perez博士。 研究人员打算继续合作研究应用于钢铁基材的保护涂层。 在该项目的初始阶段，研究人员利用两种工艺对IFUNAM提供的钢基材进行涂覆，探索耐磨涂层性能。涂层成功应用，并建立了冶金债券的所有工艺条件。这种键对于任何涂层技术的成功工业应用都是必不可少的。 这一阶段的合作将研究由于复合材料和钢之间的热膨胀不匹配而导致的沉积涂层问题。特别是，研究人员打算通过在耐磨外层中添加合适的应力消除夹层来解决这些问题。 MMI制造的样本将由IFUNAM进行高应力磨损试验、腐蚀试验和氧化试验。 通过这种合作开发的技术能够迅速转移到工业用途。 通过使用改进的保护性钢涂层延长设备的使用寿命，该项目将对两国产生工业效益。

Stiglich 9815044This U.S.-Mexico award, jointly funded by the Divisiojn of Civil and Mechanical Engineering, the Division of Design, Manufacture, and Industrial Innovation, and the Division of International Programs, will provide support for a collaborative research project between Dr. Jacob J. Stiglich, Materials Modification, Inc. (MMI), and Dr. Ramiro Perez at the Institute of Physics of UNAM (IFUNAM), Cuernavaca, Mexico. The investigators intend to continue cooperative research on protective coatings applied to steel substrates. Under the initial stages of the project, the researchers explored wear resistant coating performance utilizing two processes to coat steel substrates supplied by IFUNAM. Coatings were successfully applied and metallurgical bonds were established for all process conditions. Such bonds are essential for the successful industrial applications of any coating technology. This stage of the collaboration will investigate problems with deposited coatings due to the great thermal expansion mismatch between composites and steel. In particular, the investigators intend to address these problems by adding suitable stress relieving interlayers to the wear-resistant outer layer. Specimens manufactured by MMI, will be subject to high stress wear testing, corrosion testing and oxidation testing by IFUNAM. Technologies developed by this collaboration are capable of rapid transfer to industrial usage. By extending equipment life-cycles with the use of improved protective steel coatings, this project should be of industrial benefit to both countries.
