A coating for a blade root/disk interface includes a layer of soft metal matrix, and a solid lubricant distributed through the soft metal matrix. Examples of materials include CuAl as the soft metal matrix and MoS.sub.2 as the solid lubricant, although others are also disclosed.

Provided are: a sintering binder including nanoparticles, a method for producing the sintering binder, and a method for bonding using the sintering binder. The sintering binder mainly includes cuprous oxide nanoparticles, combines particle stability with bondability, and less undergoes ion migration. A composite particle including metallic copper with the remainder being cuprous oxide and inevitable impurities is used for bonding typically of metals. The composite particle structurally includes metallic copper dispersed inside the particle and has an average particle size of 1000 nm or less.

A sintered bearing includes, on an inner peripheral surface, a cylindrical portion and a one-side increased-diameter portion, which are provided so as to be continuous in the axial direction. An end portion of one side in the axial direction of the cylindrical portion and an end portion of another side in the axial direction of the increased-diameter portion coincide, and the cylindrical portion and the increased-diameter portion are molded by performing sizing on a sintered compact having a tubular shape, which is introduced into a die.

The present invention provides a thick-film paste for printing the front side of a solar cell device having one or more insulating layers. The thick film paste comprises an electrically conductive metal, and a lead-tellurium-lithium-oxide dispersed in an organic medium.

The present invention relates to a powder for sintering containing a mixture of a metal powder and metal oxide particles having an average particle diameter of 5 nm or more and 200 nm or less, and to a sintered body.

An iron powder and method of making an iron powder. The method includes a step of neutralizing an acidic aqueous solution containing a trivalent iron ion and a phosphorus-containing ion, with an alkali aqueous solution, so as to provide a slurry of a precipitate of a hydrated oxide, or a step of adding a phosphorus-containing ion to a slurry containing a precipitate of a hydrated oxide obtained by neutralizing an acidic aqueous solution containing a trivalent iron ion with an alkali aqueous solution. A silane compound is added to the slurry so as to coat a hydrolysate of the silane compound on the precipitate of the hydrated oxide. The precipitate of the hydrated oxide after coating is recovered through solid-liquid separation, the recovered precipitate is heated to provide iron particles coated with a silicon oxide, and a part or the whole of the silicon oxide coating is dissolved and removed.
