Titanium is very strong in relation to its low weight making it very interesting for lightweight applications. However, use of titanium in certain aircraft components is limited as it is a relatively soft metal that quickly deteriorates when mechanically stressed. A nitriding heat treatment was developed for Ti64 with aim to improve wear properties without negative effect on fatigue and strength.
