A method for remediating fractures in a cement structure including heating the cement structure to a temperature at or above the melting temperature of the eutectic metal alloy particles to allow the particles to flow in liquid state into the fractures in the cement structure until the heat source is discontinued, allowing the particles to cool and solidify.

The present disclosure is drawn to hybrid media sheets, ink-receiving layer compositions for coating on a media substrate, and a method of making hybrid media sheets. The hybrid media sheet scan have a media substrate with a front barrier layer, a back barrier layer, an adhesion promoting layer applied to the front barrier layer, and an ink-receiving layer applied to the adhesion promoting layer. The ink-receiving layer can include a water-soluble polymer, a mordant, and particles of a metal- or semimetal-oxide.

A process for manufacturing an abradable layer, includes compressing a powder composition including at least micrometric ceramic particles having a number-average form factor greater than or equal to 3, a mass content of said micrometric ceramic particles in the powder composition being greater than or equal to 85%, the form factor of a particle being defined as the ratio [largest dimension of the particle]/[largest cross-sectional dimension of the particle], and sintering the powder composition thus compressed to obtain the abradable layer, wherein a temperature imposed during sintering, the sintering time and the compression pressure applied are selected so as to obtain a volume porosity rate of the abradable layer greater than or equal to 20%.

A cemented tungsten carbide body is formed by mixing a tungsten carbide powder and a cobalt powder together to form a powder mixture. The tungsten carbide powder makes up greater than or equal to 80 weight percent of the powder mixture, while the cobalt binder powder makes up about 1.5 weight percent to about 20 weight percent of the powder mixture. Next, the powder mixture is compacted to form a green compact, and a boron nitride coating is applied to a surface of the green compact to form a coated compact. The coated compact is sintered at a temperature sufficient to melt the cobalt powder, such that boron from the boron nitride coating diffuses into the compact and creates a gradient of metallic cobalt and boron extending inward from the surface. The metallic cobalt content increases from the surface inward, while the boron content decreases from the surface inward.
