Ti alloy poppet valve and a method of manufacturing the same |
| abstract |
A Ti alloy poppet valve consists of a valve stem and a valve head, and is employed as intake or exhaust valve in an internal combustion engine of an automobile. O 2 is put into the valve in a furnace at very slight amount and heated to introduce oxygen atoms into titanium of the valve to form a Ti-O interstitial solid solution without making titanium oxides. The valve is strengthened to increase hardness and wear resistance. |
