Title: Surface treatment method of fabricated metal product
Inventor: TERAKADO KAZUYOSHI
IPC: C23C8/36
Filed: 1980-01-23
Abstract: PURPOSE:To form a cemented layer selectively on the desired place on the surface of fabricated metal product by a method wherein the surface temperature of a fabricated metal product is partially increased, deep high carbon concentration is formed at that part of ion carburized nitride layer, and then is quenched. CONSTITUTION:A container 5 containing a shaft 1 to be treated is vacuumed to 10<-2> Torr or below, then a mixed gas of N2, CH4, and H2 is introduced 14 until 5 Torr is reached. Then, glow discharge is generated by applying 300-1,500V  across the container 5 that forms anode and a cathode support 6. As this pattern, of  an ion carburized nitriding treatment at 600 deg.C for 5hr, during first 40min and last 20min, gas pressure is reduced from 5 Torr to 3 Torr. This pressure reduction combines the negative glow region of the glow-discharge between a stopper 4 and a  cathode discharge auxiliary electrode 11. As a result, only at the stopper part 4, carburization temperature increases to about 850 deg.C. Then, the stopper part 4 is heated with high-frequency, is quenched with water, and is annealed. The process hardens  only the stopper part 4 with carburized nitriding treatment reaching to effective  depth.
