Double spray forming machine and its applications to layered light-metals materials production

Abstract

In current paper we present a new additive manufacturing method of production of bulk/macroscopic double-layer metallic materials by a unique Double Spray Forming machine in situ under a protective high-purity argon atmosphere. This method allows direct layer by layer deposition of metallic materials with good interlayer adhesion without formation of internal oxides. The double-layered materials including metal 1/metal 2, crystalline alloy 1/crystalline alloy 2 and crystalline alloy/glassy (amorphous) alloy were produced. The resulting materials consist of a combination of a relatively hard layer 1 and a relatively soft layer 2, thus making an in-situ layered composite “inlaycom”. The obtained structures were examined by X-ray diffractometry and scanning electron microscopy. The paper is focused to show the principle of the process usable as a scientific instrument. The proposed method can be applied for production of other double layer metallic materials including crystal/glassy ones and can be used by the scientists and engineers working in various research fields.
