I have 39 years of experience, and specialize in the field of metallurgical engineering with specific knowledge in the areas of failure analysis, high temperature metallurgical processing and high temperature coatings. I have published on such topics as simultaneous diffusion coating of external airfoil surfaces and internal serpentine cooling passages, heat treat cycle reduction for nickel base superalloys and cost effective replacement of pack cementation aluminide and chromide coatings for aeroderivative abd IGT hot zone components. I have testified on failed aluminum alloy ladder, failed aluminum alloy culvert and failed 96″ diameter watermain.
