Method for handling a slag pot or ladle or pyro-metallurgical tools comprising the steps of spraying a mineral suspension onto a wall and putting into service of said slag pot or ladle or of the pyro-metallurgical tool, wherein said mineral suspension comprises calcium particles in suspension in an aqueous phase forming a calcium particle slurry containing a carbon hydrate at a content between 0.2 and 3%.

Aspects include supplying a plurality of nickel-enriched braze powder particles to a cold spray system through a particle supply inlet. The nickel-enriched braze powder particles are accelerated through a transfer tube and out an exit in the transfer tube towards a substrate to produce a braze cold-sprayed substrate. A component surface is positioned proximate to the braze cold-sprayed substrate. The braze cold-sprayed substrate is heated to bond the braze cold-sprayed substrate to the component surface.

A method for laser-processing a metallic surface to produce a functionalized metallic surface comprises: providing a material substrate having the surface; and applying a pulsed laser beam to a region of the surface, the pulsed laser beam being applied at a non-normal angle to the surface, wherein material in the region of the surface ablates due to the applied pulsed laser beam and wherein at least a portion of the ablated material redeposits on the surface to produce one or more material-coated structures angled at the non-normal angle with respect to the surface, wherein the surface having the one or more material-coated structures is the functionalized surface. The functionalized metallic surface has broadband directional emissivity independent of polarization.

The second surface includes inclined surfaces having inclination angles ?1 and ?2 of larger than or equal to 30? and smaller than 90? with respect to the first surface. An open end of the through hole in the second surface is formed in the inclined surfaces.

A sliding member of the present invention includes a base material and a coating layer that is formed on the base material. The coating layer includes a particle aggregate, and the particle aggregate contains two or more kinds of precipitation hardened copper alloy particles that have different compositions. The sliding member has high coating strength and superior wear resistance.

The disclosure relates to a process for depositing nanoparticles on a substrate and comprising the following steps: a) generating an aerosol from a suspension of nanoparticles in a liquid; b) generating, with the aerosol, a jet of nanoparticles in a carrier gas, under vacuum; c) depositing said nanoparticles of the jet on a substrate; characterised in that step a) is carried out using a surfactant-free suspension in which the nanoparticles comprise a core made of a conductive or semiconductor material coated by a shell made of a non-metallic material.

The disclosure also relates to a substrate obtained by said process.

The present invention relates to a method for coating large area solid substrates with titanium by reacting the substrate surface with a mixture comprising titanium halide or subhalide powders in the presence of a reducing agent.
