Stainless steel 316 abstract Amorphous carbon (a-C) film about 3 mm in thickness is coated on 316L stainless steel by close field unbalanced magnetron sputter ion plating (CFUBMSIP). The AFM and Raman results reveal that the a-C coating is dense and compact with a small size of graphitic crystallite and large number of disordered band.

A cost model was developed and used to predict the cost to produce type 316 stainless steel, Ni-based alloys C-276 and C-22, and the iron-based amorphous metals discussed here. This model's assumptions for the costs of the raw materials required to produce all of these materials were taken from compilations of the United States Geological Survey.

Amorphous graphite is a seam mineral, not to be confused with a vein mineral. It is formed by the metamorphism of previously existing anthracite coal seams. Proto-coal organic carbon is deposited and converted into anthracite coal followed by low grade metamorphism of the coal. This results in the formation of microcrystalline graphite.

Abstract. Compact coatings of ''amorphous'' boron were deposited on a smooth surface of a substrate such as graphite, refractory metals, iron, and stainless steel using the reduction of boron trichloride by hydrogen. With a constant surface temperature, and a low deposition efficiency, a constant thickness is obtained if transport limitations ...

Amorphous Metal Defined An amorphous metal is a solid metallic alloy material that exhibits an unusual atomic-scale structure compared to all other metals. Most metals are crystalline in their solid state. Their atoms are arranged in a highly-ordered state. Amorphous metals, on the other hand, have a disordered arrangement of atoms and are non-crystalline with […]
