A turbine engine part includes at least a substrate, and present on the substrate, a ceramic coating for protection against calcium and magnesium aluminosilicates, the ceramic coating including AlOat a molar content lying in the range 33% to 49%, YAlOat a molar content lying in the range 21% to 53%, and yttria-stabilized zirconia at a molar content lying in the range 13% to 31%.

Turbine engine part coated with a protective ceramic coating, method for manufacturing and for using such a part

The invention relates to an alloy having high temperature mechanical strength in an oxidizing medium and comprising a carbide-precipitation-strengthened matrix containing chromium. The invention is characterized in that the alloy comprises carbides of at least one metal (M) selected from among titanium, zirconium and hafnium, said carbides also optionally containing (M') tantalum. The invention is suitable for articles that require high temperature mechanical strength, such as for hot glass processing or production.

Refractory alloy and mineral wool production method

Cobalt based alloys exhibiting high-temperature mechanical strength in an oxidizing medium are provided. The alloys are free of W and Hf and include the following elements in percentage by weight of the alloy: 23 to 34% Cr; 6 to 12% Ni; 6.0 to 10% Ta; 0.3 to 1.2% C; less than 3% Fe; less than 1% Si; less than 0.5% Mn; less than 0.1% Zr; and a balance of cobalt and impurities. Ta/C molar ratios of the alloys are at least 0.3.

Process for manufacturing mineral wool, cobalt-based alloys for the process and other uses

An alloy, characterized in that it contains the following elements (the proportions being indicated in percentages by weight of the alloy): the balance consisting of cobalt and inevitable impurities. An article for the manufacture of mineral wool, especially fiberizing spinner, made of such an alloy.
