• A coating system consisting of a superalloy substrate, a MCraly bondcoat and the doped thermal barrier is tested under extreme temperature gradient conditions in a laboratory. Visible is the (bluish) flame of the burner impinging on the coating. The surface temperature is about 1,250ºC. The substrate is kept at much lower temperatures. Typical gradients of 200K to 300K are achieved over a coating thickness of 300μm.

    On a cycle – thermal barrier coatings

    Materials World magazine
    Trials of a novel phosphor-doped thermal barrier coating (TBC) have been completed at RWE npower’s power station in Didcot, UK. Tested for 4,000 hours in a Siemens V94.3 (A) gas turbine, the doped yttria-stabilised zirconia (YSZ) coating is said to have remained in good condition, while the conventional YSZ TBC delaminated.
  • Probing hardmetal

    Materials World magazine
    Scientists in France and Sweden have made progress in understanding why some properties of hardmetal improve when doped with vanadium. The findings could help manufacturers control the hardness and durability of hardmetal.
  • Low–porosity ceramic tiles

    Materials World magazine
    Improved stain resistance in polished ceramic tiles may now be possible, say researchers at the Instituto de Ceramica y Vidrio in Spain, who have introduced an organic fugitive phase during liquid sintering of green tiles to achieve reduced porosity volume with various pore sizes.
