Title:
ENVIRONMENTAL BARRIER COATING AND METHODS OF FORMING THE SAME
Document Type and Number:
Japanese Patent JP2017165644
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide methods of forming an environmental barrier coating (20).SOLUTION: A method includes disposing a powder-based coating on a substrate (12), heat-treating the powder-based coating at a temperature greater than 800°C and less than 1200°C to form a porous coating that includes surface-connected pores, infiltrating at least some of the surface-connected pores of the porous coating with an infiltrant material to form an infiltrated coating, and sintering the infiltrated coating at a temperature greater than 1200°C and less than 1500°C to form an environmental barrier coating (20) on the substrate (12).SELECTED DRAWING: Figure 2
