Abstract:

X-Metal is an ore concentrate obtained from a mine which is located in California. The original ore assays 7 metallics, and by crushing, classifying, flotation, and concentration of 14 to 1, a product is obtained which is called X-Metal. This concentrate is ball-milled to about 100 mesh size for the spray material. The mechanism of spraying consists of the introduction of the powder into a stream of air which propels the powdered concentrate into a reducing flame of propane. Here the small particles reach white heat before impinging upon the samples which are at room temperature. After spraying, the material is given a short heat treatment. This 1941 report sought to determine corrosion resistance in salt spray and microstructure of low carbon steel plate sprayed with X-Metal powder.
