. (Metal.) A certain process for producing upon articles of iron or steel an adherent coating of the magnetic oxide of iron (which is not liable to corrosion by air, moisture, or ordinary acids). This is accomplished by producing, by oxidation at about 1600° F. in a closed space, a coating containing more or less of the ferric oxide (Fe2O3) and the subsequent change of this in a reduced atmosphere to the magnetic oxide (Fe2O4).

(Metal.) A process of hardening the face of steel, as armor plates, invented by Hayward A. Harvey of New Jersey, consisting in the additional carburizing of the face of a piece of low carbon steel by subjecting it to the action of carbon under long-continued pressure at a very high heat, and then to a violent chilling, as by a spray of cold water. This process gives an armor plate a thick surface of extreme hardness supported by material gradually decreasing in hardness to the unaltered soft steel at the back. [ Webster 1913 Suppl. ]

n. Wrong or irregular proceding. [ 1913 Webster ]

(Photog.) A process, now no longer used, invented by J. N. Niepce, a French chemist, in 1829. It depends upon the action of light in rendering a thin layer of bitumen, with which the plate is coated, insoluble. [ Obsolescent ] [ Webster 1913 Suppl. ]
