    摘要: A ceramic thermal barrier coating (TBC) (18) having first and second layers (20, 22), the second layer (22) having a lower thermal conductivity than the first layer for a given density. The second layer may be formed of a material with anisotropic crystal lattice structure. Voids (24) in at least the first layer (20) make the first layer less dense than the second layer. Grooves (28) are formed in the TBC (18) for thermal strain relief. The grooves may align with fluid streamlines over the TBC. Multiple layers (84, 86,88) may have respective sets of grooves (90), Preferred failure planes parallel to the coating surface (30) may be formed at different depths (A1, A2, A3) in the thickness of the TBC to stimulate generation of a fresh surface when a portion of the coating fails by spalling. A dense top layer (92) may provide environmental and erosion resistance.

    摘要: This invention relates to a process for the catalytic grafting of an ethylenically unsaturated monomer onto a copolymer in the presence of a catalyst. The monomer is selected from the group consisting of ethylenically unsaturated carboxylic acids, anhydrides esters and other derivatives thereof. The copolymer is selected from the group consisting of certain copolymers of ethylene and ionomers of such copolymers. The catalyst is a mixture of (a) a certain amount of water and (b) at least one of certain phosphorus-containing compounds. The process comprises admixing copolymer, monomer, catalyst and an organic peroxide at a temperature above the melting point of the copolymer for a period of time so as to obtain a uniform distribution of monomer, catalyst and peroxide in the copolymer. The resultant grafted copolymer has improved color, and is useful in adhesive systems and as a compatibilizer for polymers and other materials.
