A highly effective thermal insulating piston concept with high projected durability characteristics has been developed by means of computer aided modelling, thermal rig bench screening, and small-bore engine testing. The piston concept is composed of a relatively low thermal conductivity titanium alloy type 6242 structural material and a 1.25 mm thick slurry densified thermal barrier coating. The piston material, structural configuration, and detail design features were selected through computer aided modelling and qualified through small-bore engine testing. Screening of plasma sprayed thermal barrier coatings was performed on a simple thermal test rig and final selection of a system was made through small-bore engine testing.
