Title: Nitride-layer-coated austenitic iron-base alloy
Inventor: IGARASHI SHIGERU
IPC: C23C8/38
Filed: 2000-07-28
Abstract: PROBLEM TO BE SOLVED: To provide an austenitic iron-base alloy coated, on the surface, with a nitride layer combining hardness with corrosion resistance and causing no decomposition even if heated to high temperature. SOLUTION: The iron-base alloy has a first nitride layer composed essentially of Cr and N and a second nitride layer having M4N-type face-centered cubic structure and 0.38-0.40 nm lattice constant. Moreover, the thickness of the first nitride layer is 5-200 nm; the thickness of the second nitride layer is 0.5-20 μm; and the first nitride layer is located on the side nearer to the surface of the iron-base alloy than the second nitride layer. For example, The alloy is set in an ion nitriding furnace, held at 300-450 deg.C for >=3 h, and subjected to ion nitriding at 400-950 V applied voltage under 0.7×102 to 13.3×102 Pa holding pressure. This nitride-layer-coated austenitic iron-base alloy can also be obtained by using gas nitriding.  In this alloy, no rusting is observed even after a lapse of 100 h at the salt spray test of JIS Z 2371 and practically no decomposition of the secondary nitride takes place even if heating is done at 500 deg.C for 2 h.
