Patent JP-H07197232-A (JP)
Title: Microshaft
Inventor: TAWARA MASAAKI
IPC: F16C3/02
Filed: 1993-12-29
Abstract: PURPOSE:To combine corrosion resistance with surface hardness by incorporating no crystalline chromium nitride into the nitrided and hardened layer of an austenitic stainless steel and incorporating specific amounts of N atoms into the structure of the outermost surface layer part. CONSTITUTION:When nitriding treatment is applied to an austenitic stainless steel at low temp., no chromium nitride is precipitate and formed. When nitrogen atoms are allowed to penetrate into the matrix phase of an austenitic stainless steel and the amount of its penetration is controlled to 2-12%, deterioration in corrosion resistance does not occur and, further, a nitrided and hardened layer having high surface hardness is formed by the penetration of the nitrogen atoms. The nitrogen atoms merely penetrate into the matrix phase of the stainless steel and form lattice strain, but it does not leat to the precipitation and formation of crystalline chromium nitride. Deterioration in corrosion resistance is caused by the precipitation of crystalline chromium nitride and the reduction in the concentration of solid-solution chromium in the matrix phase and the resulted absence of active chromium necessary to form a passivating film.
