GAS TURBINE BLADE, GAS TURBINE HIGH-TEMPERATURE MATERIAL, AND MANUFACTURE THEREOF

摘要

PURPOSE: To provide gas turbine high-temperature material capable of surely preventing the separation of a ceramics layer provided on a base material under the use condition at high temperature, and a manufacturing method thereof. ;CONSTITUTION: A bond layer 2, having the main component of either of Ni or Co or both of them and moreover containing Cr and Al, is formed on base material 1 having the main component of either of Ni or Co. Al is diffused on the bond layer 2, and then diffused Al is oxidation-treated to form an Al oxide layer 3 previously. A ceramics layer 4 is formed on this Al oxide layer 3.;COPYRIGHT: (C)1995,JPO
