Inventor: TAKAYAMA ISAMU
IPC: C22F1/00
Filed: 1997-10-09
Abstract: PROBLEM TO BE SOLVED: To evade the occurrence of heat treating strains in a valve and to improve its fatigue strength by composing it of a metastable β type titanium alloy and imparting wear resistance at least to the surface of a shaft part by oxidation treatment. SOLUTION: In the metastable type titanium alloy, deformation caused by gravity in heating at the time of inexpensive oxidation treatment hardly occurs even if its structure is the one after hot working, and, moreover, its fatigue strength is remarkably improved by aging treatment. It is essential that the shaft part 2 of an engine valve is subjected to oxidation treatment, and moreover, by subjecting the face part 4 of a bevel part 1 to oxidation treatment as well, there is no need of using an expensive copper series valve seat. As for the production of the engine valve, a valve crude shape material is obtd. from a metastable β type titanium alloy rod by hot working such as hot extrusion or the like, successively, its dimensions are finished by machining, and, thereafter, wear resistance is imparted thereto by oxidation treatment.  The hot working is executed preferably in the temp. range of 600 deg.C to the transformation point +100 deg.C.
