Jack Wood - Background & Experience

  • 33 years (9/1968 - 4/2001) at General Electric Power Systems: includes 10 years as technical leader and principal engineer in superalloy and coating development.

  • Superalloy research and development: Ni-base and Co-base alloy development; heat treatment studies; microstructural stability studies; failure analysis of gas turbine hardware; 4 patents.

             -Evaluated and selected IN-738 as GE bucket alloy (1st commercial use of 738)

             -Castability improvement studies of IN-738 leading to introduction of IN-738LC

             -Developed and patented GTD-111 (primary GE bucket alloy)

             -Developed and patented GTD-222 (latter stage nozzle alloy)

-Bucket failure analysis work on all GE gas turbine frame sizes: 3002, 5001, 5002, 6B, 7E, 7F & FA+, 9E, 9F

  • High temperature coatings: Overlay coating (MCrAlY) development: Coating type and process selection for gas turbine hardware; coating life studies on overlay and diffusion coatings; development of coating life prediction models; evaluation of serviced coatings (gas turbine applications); coating failure analysis; 3 patents.

    • Development of bucket MCrAlY and overaluminided MCrAlY Coating Systems: GT-29, GT-29PLUS, GT-33, GT-33PLUS

    • Worked with aluminide coating suppliers in developing simultaneous internal and external aluminide coating processes for cooled buckets and nozzles

    • Coating performance analyses on buckets and nozzles from all frame size machines

  • Responsibility for development and/or selection of all high temperature alloys and coatings used in most GE gas turbine hot section component designs through year 2000.
