A method for treating a field operated component (100) is disclosed which includes providing the component (100) including a ceramic matrix composite (102) and removing a first portion (106) of the component (100), forming a first exposed surface on the component. The method further includes providing a second portion (202) including the composite (102), the second portion (202) having a second exposed surface including a conformation adapted to mate with the first exposed surface. The second portion (202) is positioned in association with the component so as to replace the first portion (106), and the second portion (202) and the component (100) are joined to form a treated component (300). Another method is disclosed wherein the component (100) is a turbine component which further includes removing an environmental barrier coating from the component (100), arranging and conforming the first exposed surface (200) and the second exposed surface (204) to define a joint (302), and applying an environmental barrier coating to the treated component (300).

摘要:
A method for making a ceramic sanitary ware product (M) comprises at least the following steps: applying a uniform layer (S) of bonding material comprising a high-viscosity fluid mixture to at least one surface (2) intended to be joined to at least a second part (M3) of the sanitary ware product (M); joining the second part (M3) of the sanitary ware product (M) to the first part (M2) along a joining zone defined by two respective contact surfaces (2, 3) of the selfsame parts (M2, M3) with the layer (S) of bonding material interposed between them; drying the sanitary ware product (M) thus obtained; immediately after the step of joining the two parts (M2, M3), there is a step of applying, through the agency of respective means (4), a flow (F) of electric charge uniformly distributed at least along the joining zone at a predefined intensity (A) and for a predetermined length of time (T) so as to increase mechanical strength at least at the joining zone.
