Abstract
We have measured the thermal conductivity of a ni20Cr / 8% yttria-partially-stabilized-zirconia functionally graded 1.1 mm thick coating on a substrate of 403 stainless steel. We measured thermal conductivity of the as-received coated specimen, then thermally shocked the specimen and measured thermal conductivity again. The measurements were done using an absolute, steady-state technique over a temperature range from 400 K to 1200 K. The specimen was thermally shocked by heating in a furnance to 475 K, then quenching in water at 295 K. We discuss the effect of moderate thermal shock on the thernal conductivity of the coating.Conference Dates
