Title:
CONSTRUCTION METHOD FOR HEAT-PROOF COATING, HEAT-RESISTANT MEMBER, AND GAS TURBINE
Document Type and Number:
Japanese Patent JP2015004132
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a construction method for a heat-proof coating having a high heat cycle durability and a high thermal insulation.SOLUTION: A construction method for a heat-proof coating comprises: the step of forming a bond coat layer 2 on a heat-resistance alloy substrate 1; and the step of forming a top coat layer 3 on the bond coat layer 2. The step of forming the top coat layer 3 includes: the step of forming a plurality of ceramic films 3a by a flame spray; and a step of performing a temperature control so that the surface temperature, as measured at the ending time of the formation of the top coat layer 3, of the top coat layer 3 may be 450°C or lower.
