ABSTRACT:
A molten metal gas-atomizing spray-depositing apparatus has an atomizer which employs a pressurized gas flow for atomizing a stream of molten metal into a spray pattern of metal particles and for producing a flow of the particles in the pattern thereof along with the pressurized gas flow in a generally downward direction. The apparatus also has a substrate, such as composed of stainless steel, disposed in spaced relation below the atomizer with at least an upper surface layer of a glass thereon, being thermally softenable over a broad predetermined temperature range. The pressurized gas flow impinges on the glass surface layer of the substrate which receives a deposit of the particles in the spray pattern to form a product thereon. The use of a glass which will soften over a broad predetermined temperature range but still retain a viscosity of sufficient strength to prevent it from being blown away by a pressurized atomizing gas flow and thereby maintain its capability to function as a substrate results in a reduction of porosity and an improvement of flatness of the deposit bottom surface located in contact with the glass substrate surface.
