Dr. Gregory Smith is a Materials Scientist and Professional Engineer licensed in New York, Connecticut, New Jersey, Massachusetts, and Maryland, with a B.E. in Engineering Science, a B.S. in Marine Sciences, and a Ph.D. in Material Science and Engineering from Stony Brook University, State University of New York. Dr. Smith has experience in the analysis and forensic investigation of failures and other technical issues related to mechanical equipment, products, components, and systems. Dr. Smith’s experience has included a focus on both research and development and practical engineering-related failure analysis, statistical process control, process and design engineering, and mechanical/thermal testing. He has over 10 years of experience working with surface engineering and protective coatings for corrosive, marine, and other harsh environments and for general corrosion protection, involving paints, polymers, and cladding.

Dr. Smith has experience with and has inspected various aerospace-, sea-, and land-based power generation systems, heavy machinery equipment, chemical processing equipment, boilers, furnaces, water heaters, HVAC systems and components, valves/actuators, heat exchangers, plumbing and piping system failures (including valves, unions, fittings, piping and joints in copper, brass, steel, stainless steel, PEX, PVC/CPVC, and other materials), weld failures, metallurgical, and fire protection system failures. He combines both his background in materials science and mechanical engineering to provide an in-depth analysis of complex system and component failures.

Dr. Smith began working as a process engineer with a start-up firm developing characterization tools and sensors for process measurement of thermal spray deposition activities. This included advancing a DARPA-funded non-distributive evaluation (NDE) inspection program using flash infrared thermography (FIT) to identify and visualize defects below spray-coated Navy ship decks using a digital image correlation algorithm that he developed.

He extended his NDE coating inspection focus internationally at GKN Aerospace Engines Sweden, where he implemented an eddy current-based thickness probe for contact thickness measurement of complex geometry ceramic thermal barrier coating (TBC) layers applied to a range of FeCrAlY and NiCoCrAlY metallic bond coats and Fe, Ni, and Ti-based substrates. Additionally, Dr. Smith supported statistical process control and process engineering for commercial aerospace-, land-, and sea-based power generation gas turbines in the development of test reduction plans, to reduce QC/QA test burdens, and supported failure analysis on critical systems.

Dr. Smith’s materials graduate work focused on mechanical property characterization of thermal spray and cold spray coating systems. Externally facing, he heavily supported an Army Futures Command program developing temperature-resistant diesel piston coatings for improved power generation on track vehicles. Additionally, he supported process parameter development and mechanical testing for aerospace original equipment manufacturer (OEM) components, such as Al2O3 clearance coatings in turbine compressor sections and WC-CoCr and CrC-NiCr hard-chrome alternative materials in landing gear struts, where resistance to fatigue and impact-based damage was a primary concern.

As a Materials Research Engineer for the US Navy, Dr. Smith supported shipyards, warfare centers, regional maintenance centers, and Navy technical authorities on a wide range of corrosion-related mitigation and prevention efforts. He was recognized as an expert in surface preparation, non-skid materials, and research and development within NAVSEA 05P Coatings and Corrosion Control technical pyramid and directly supported updates to NAVSEA Standard Item 009-32 and 009-124 to improve technology transfer to shipboard and fleet operation. Dr. Smith worked with a range of polymeric and thermal spray coatings systems under MIL-PRF-32577, -23236, and -24667, and with a range of aluminum, stainless steel, CuNi, Inconel, and high-yield carbon steel material components. Additionally, he is certified as a NACE/SSPC Level 1 Coatings Inspector.

Dr. Smith is an active member of ASM’s Thermal Spray Society sub-committee and involved in the publication and peer-review of the Journal of Thermal Spray Research papers. He additionally mentors and supports graduate students at his alma mater and participates as a member of the Department of Materials Science and Engineering’s Industrial Advisory Board (IAB).
