Abstract: A method includes masking at least one hole of an article with a paste, wherein the hole opens onto a surface of the article, applying a coating to the surface of the article, and removing the paste including contacting the paste with water, leaving at least one open hole in the surface of the coated article. The paste includes about 40-80 wt % of a filler material, about 0.5-20 wt % of an inorganic binder, about 0.5-15 wt % of a polyhydroxy compound and about 5-25 wt % of water. The filler material includes a first material which includes alkali metal doped alumina, zirconium oxide, titanium oxide, silicon dioxide, or a combination thereof and a second material which includes a silicate. A weight ratio between the first and second materials is in a range of about 1-10.

Abstract: An apparatus is disclosed, including a first article, a second article, at least one interface structure, and a thermal break directly adjacent to the at least one interface structure. The first article includes a first material composition having a first thermal tolerance. The second article includes a second material composition having a second thermal tolerance greater than the first thermal tolerance. The first article and the second article are in contact with one another through the interface structure. The thermal break interrupts a thermal conduction path from the second article to the first article.

Abstract: A method for treating a field operated component is disclosed which includes providing the component including a ceramic matrix composite and removing a first portion of the component, forming a first exposed surface on the component. The method further includes providing a second portion including the composite, the second portion having a second exposed surface including a conformation adapted to mate with the first exposed surface. The second portion is positioned in association with the component so as to replace the first portion, and the second portion and the component are joined to form a treated component. Another method is disclosed wherein the component is a turbine component which further includes removing an environmental barrier coating from the component, arranging and conforming the first exposed surface and the second exposed surface to define a joint, and applying an environmental barrier coating to the treated component.

Abstract: A method includes masking at least one hole of an article with a paste, wherein the hole opens onto a surface of the article, applying a coating to the surface of the article, and removing the paste including contacting the paste with a water containing liquid/environment to dissolve or re-disperse the paste, leaving at least one open hole in the surface of the coated article. The paste includes about 20-80 wt % of a filler material, about 0.5-20 wt % of a hydrogen phosphate compound, about 0.5-15 wt % of a polyhydroxy compound and about 5-25 wt % of water. The filler material has an average particle size in a range of about 0.1-100 microns, and includes a first material which includes alkali metal doped alumina, zirconium oxide, titanium oxide or a combination thereof and a second material which includes a silicate. A weight ratio between the first and second materials is in a range of about 1-10.
