Title: Jig for surface treatment device
Inventor: WATANABE NORIKO
IPC: C23C8/36
Filed: 1985-01-28
Abstract: PURPOSE:To make possible the easy treatment of the required part of slender bars as well in the stage of subjecting locally the surface of metallic members to a surface treatment such as heat hardening by covering the part of the metallic members to be treated with a member having a large coefft. of thermal expansion except the treating part thereof then subjecting the same to the surface treatment. CONSTITUTION:The bar 15 to be treated such as wire rod having <=1mm diameter is sandwiched by covers 11, 12 which are made of brass, etc. having the coefft. of thermal expansion larger than the coefft. of thermal expansion of the bar 15 and have semicircular hollow grooves 13, 14 and the part 15a to be subjected to the surface treatment such as hardening is projected to the outside of the covers 11, 12 and is compressively held by holding members 16 in the stage of subjecting partially the above-mentioned bar 15 to the surface treatment such as heat hardening. Such bar is put into a vacuum reaction vessel and is set with the part 15a faced upward. A treating gas such as N2 is introduced into the reaction chamber and is ionized by the high voltage impressed thereto. The surface of the bar is hardened by the ionitriding. The covers 11, 12 expand by the effect of high temp. during the treatment to eliminate the space between the grooves 13, 14 and the bar 15. The surface hardening treatment of only the required part 15a by the ionitriding is thus executed without the intrusion of the cation of the gaseous N2 into the parts except the part 15a.
