Heavy-duty Marine Gas Turbine Project. Task 1/6. Operational Performance and Maintenance Improvement. Final Report. Volume B. Materials Development,

摘要

This document describes part of the work performed within Task 1/6,Operational Performance and Maintenance Improvement,of the Heavy-Duty Gas Turbine Development Program or MARAD Project. The MARAD Project is an integrated effort to develop the heavy-duty gas turbine as an alternate competitive form of marine propulsion. This Volume B covers materials development efforts;Volume A covers rig testing and fuel additive development,and Volume C encompasses other research efforts. This volume describes research efforts directed toward establishing the best discrete materials(s) for application in residual fuel-burning gas turbines. A large number of materials were concurrently investigated initially: (1) alloys: (2) composites; (3) EB coatings; (4) claddings; (5) diffusion coatings,and (6) ceramics. Intensive development evaluations (including fabrication of trial components) showed the sheet cladding to be the best material.
