    摘要: A spray forming pattern of a first metal having a melting point at a first temperature is formed. The spray forming pattern has a surface defining a cavity that has the shape of a master pattern. Steel particles having a carbon content in the range of 0.01-0.9% by weight are sprayed onto the spray forming pattern to form a deposit on the spray forming pattern. The deposit has a thickness of at least 0.5 inches and the temperature of the steel particles increases as the thickness of the steel deposit increases. The spraying conditions are controlled so that the steel particles coming into contact with the spray forming pattern results in a surface temperature of the spray forming pattern of less than about 80.degree. C. The deposit and the spray forming pattern are heated to a second temperature, which is higher than the first temperature, to melt the spray forming pattern from the deposit. The resulting deposit has the general shape of the master pattern.

    摘要: A method of reducing distortion in a spray formed rapid tool includes the steps of making a model of a desired tool and constructing a ceramic pattern as the inverse of the model. The method also includes the steps of building a thermal model of the desired tool from a solid model of the ceramic pattern and applying thermal boundary conditions to the thermal model based on known conditions. The method also includes the steps of running the thermal model to produce a temperature distribution of the desired tool and determining any temperature deviations in the temperature distribution above a predetermined value. The method further includes thermally spraying a metal material against the ceramic pattern to form the desired tool if there are no temperature deviations in the temperature distribution above the predetermined value.

    摘要: A method of spray forming a weldable metal deposit. The method comprises (a) providing a ceramic spray forming pattern, (b) heating the spray forming pattern to a sustained temperature sufficient to prevent internal stress formation in deposited carbon steel having a carbon content of less than about 0.3 weight percent when deposited on the heated spray forming pattern, (c) spraying metallic particles onto the spray forming pattern heated to the sustained temperature, and (d) allowing the sprayed metallic particles to cool to form a metal deposit. The metallic particles have a carbon content which is sufficient to result in metal particles having a carbon content of less than about 0.3 weight percent when deposited on the heated spray forming pattern. The resulting deposit has a carbon content of less than about 0.3 weight percent.

    摘要: Method of sprayforming bulk metal deposits that replicate a master pattern: (i) casting and solidifying ceramic about a master pattern to form a spraying pattern; (ii) after removing the spraying pattern from the master pattern, heating the ceramic spraying pattern to a sustained temperature to effect an isothermal diffusion dependent microstructural transformation; (iii) while in such heated condition, thermally spraying allotropic metal particles onto the heated spraying pattern to form a deposit having a bulk thickness, the particles impacting the spraying pattern, or previously deposited particles, at a temperature above the sustained temperature of the spraying pattern; (iv) holding the deposit on the heated spraying pattern sufficiently long enough to allow the particles of the deposit to undergo a diffusion reaction that relieves internal stresses due to deposition and solidification; and (v) thereafter gradually cooling the deposit to room temperature to produce a unitary article with essentially no distortion relative to the spraying pattern.

    摘要: Method and arrangement for spray forming an article. The method includes spraying a plurality of metal streams upon a low-heat resistant model and thereby forming a spray formed article. Each of the plurality of metal streams is composed of moltenized droplets, and as between the plurality of metal streams, each is composed of different constituent elements. In the spray form process, conditions of the metal streams are controlled, particularly around the time that the droplets land, to prevent adverse affects such as melting or burning the master model. The spray conditions are controlled in such a manner that the individual metal droplets forming the metal streams remain substantially segregate. The segregated state is maintained through out solidification so that the resulting spray formed article is composed at least partially of psuedo-alloy.
