The seal assembly can have a support ring having an annular shape defined around a seal axis, and a plurality of strips of a metal material, each strip of the plurality of strips being folded along a length of the strip forming a fold and a pair of segments extending radially inwardly from the fold, relative the seal axis, the fold secured at the support ring, the fold having a bending radius defined around a bending axis, the bending axis oriented parallel to the seal axis, the plurality of strips being arranged circumferentially relative one another, around the seal axis.

A protection method, protects at least one hollow internal area of a turbine engine part made of a superalloy from oxidation and/or corrosion, wherein the at least one hollow inner area has been formed by means of at least one core made of a ceramic material limited by an external surface that surrounds it. Before bringing the superalloy around the core made of a ceramic material, the external surface is coated with a material that includes a nanometric layer of hafnium (Hf), and/or a micrometric layer of platinum (Pt), or mixture at least of hafnium and platinum.

A method for limiting void formation in a melt-infiltrated ceramic matrix composite (MI-CMC) component includes arranging one or more infiltrant feedstocks in fluid communication with a targeted area of the MI-CMC component. The one or more infiltrant feedstocks have a nominal melting point at or below a nominal melting point of an alloy within the MI-CMC component. The method includes heating the one or more infiltrant feedstocks to a first temperature at or above the nominal melting point of the one or more infiltrant feedstocks to form a molten phase. The method also includes infiltrating the targeted area of the MI-CMC component with the molten phase. As such, the molten phase reacts with a solid phase in the targeted area of the MI-CMC component. Further, the method includes cooling the MI-CMC component to a second temperature that is below the first temperature to solidify the molten phase.
