Abstract
An article includes a substrate formed of a molybdenum-based alloy. The molybdenum-based alloy has a composition that includes molybdenum, silicon, and boron. A barrier layer is disposed on the substrate. The barrier layer is formed of at least one noble metal.
Claims17
An article comprising:
- a substrate formed of a molybdenum-based alloy, the molybdenum-based alloy having a composition including molybdenum, silicon, and boron;
- a barrier layer disposed on the substrate, the barrier layer formed of at least one noble metal;
- and
- a metal interlayer disposed between the substrate and the barrier layer.

A method of fabricating an article, the method comprising:
- depositing a barrier layer onto a substrate formed of a molybdenum-based alloy, the molybdenum-based alloy having a composition that includes molybdenum, silicon, and boron, and the barrier layer having at least one noble metal;
- and
- prior to depositing the barrier layer, depositing a metal interlayer onto the substrate.
A gas turbine engine comprising:
- at least one an engine section, the at least one engine section selected from the group consisting of a compressor section, a combustor section, and a turbine section, the at least one engine section having a turbine engine component including,
- a substrate formed of a molybdenum-based alloy, the molybdenum-based alloy having a composition including molybdenum, silicon and boron;
- a barrier layer disposed on the substrate, the barrier layer formed of at least one noble metal;
- and
- a metal interlayer disposed between the substrate and the barrier layer.
