OPEN VESSELS AND THEIR USE
Vessels selected from crucibles, pans, open cups and saggars essentially comprising of two components, from which (A) one component being a ceramic matrix composite, and (B) the second component being from metal or alloy, and wherein component (A) is the inner one.
Compliant layer for ceramic components and methods of forming the same
An apparatus includes a ceramic matrix composite (CMC) component and an interface coating on the CMC component, wherein the interface coating includes a layer of at least one of the following compositions: 40-50 wt % Nb, 28-42 wt % Al, 4-15 wt % Cr, 1-2 wt % Si; 90-92 wt % Mo, 4-5 wt % Si, 4-5 wt % B; or 60-80 wt % V, 20-30 wt % Cr, 2-15 wt % Ti.
INCREASING THE DENSITY OF A BOND COAT
An example method may include applying a bond coat comprising silicon or a silicon alloy on a surface of a ceramic or ceramic matrix composite substrate, where the bond coat comprises a plurality of pores; infiltrating a precursor into at least some pores of the plurality of pores; and heat-treating the bond coat and the precursor, where after heat-treating a porosity of the bond coat is less than about 5 vol. %, and where after heat-treating, the bond coat is substantially free of continuous porosity extending through a thickness of the bond coat.
PHOTOVOLTAIC CONCRETE, ITS METHOD OF MANUFACTURE AND CONSTRUCTION ELEMENT INCLUDING SUCH A CONCRETE
