摘要:
A metal surface infused composite object made by thermal spraying a metal material onto a release agent coated pattern, followed by vacuum infusion at least a portion of the metal material layer with a resin and then separating the composite infused metal object from the pattern.

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.

A method of making a spray formed article includes the steps of providing a sand pattern and spraying metal material toward the sand pattern to form the desired article. The sand pattern is made from a sand molding composition comprising refractory materials and binder. The refractory material comprises at least about 15 weight percent alumina, based on the total weight of the refractory material.

摘要:
The present invention relates to a method of providing a spray formed composite article. The method comprises providing a first article. The first article is a spray formed article. A second article is located adjacent the first article. Metallic particles are sprayed onto the articles and allowed to form a metal deposit that extends between and connects the first and second articles.
