Calcium-magnesium-aluminosilicate resistant coating and process of forming a calcium-magnesium-aluminosilicate resistant coating |
摘要 |
A process (101) of forming a calcium-magnesium-aluminosilicate (CMAS) penetration resistant coating, and a CMAS penetration resistant coating are disclosed. The process includes providing a thermal barrier coating (110) having a dopant (112), and exposing the thermal barrier coating (110) to calcium-magnesium-aluminosilicate (114) and gas turbine operating conditions. The exposing forming a calcium-magnesium-aluminosilicate penetration resistant layer (201). The coating includes a thermal barrier coating composition (110) comprising a dopant (112) selected from the group consisting of rare earth elements, non-rare earth element solutes, and combinations thereof. Additional or alternatively, the coating includes a thermal barrier coating (110) and an impermeable barrier layer or a washable sacrificial layer positioned on an outer surface of the thermal barrier coating. |
