Title: Production of endless metallic ring
Inventor: NAKAJIMA KATSUYUKI
IPC: C23C10/24
Filed: 1996-10-09
Abstract: PROBLEM TO BE SOLVED: To obtain good wear resistance and durability in a short time in a ring by subjecting an endless metallic ring after rolling to salt bath nitriding treatment under specified conditions. SOLUTION: A ring produced by welding a managing steel sheet is subjected to solution treatment and cold rolling and is thereafter immersed in a salt bath heated at 520 to 530 deg.C for only 10 to 25min. In this way, a nitriding layer with a depth the same as that obtd. by the conventional gas soft-nitriding at 480 deg.C can be obtd. in an extremely short time. Namely, with the control depth of the nitriding layer as 12 to 25μm, for obtaining this, it has been taken for 2 to 6hr heretofore, but, the time can remarkably be reduced to 10 to 25min at 529 to 530 deg.C in the salt bath nitriding. In the case this temp. is made higher, the time allowable for holding the control depth is made too high, so that the operation is made difficult. Conversely, the temp. is made lower, the time is getting longer to drop the productivity.
