Titanium coatings

I am a senior mechanical engineering student working a senior project for an aerospace company in Indiana. A problem has been identified about wear on titanium parts mated with steel parts. We are searching for a coating to apply to the titanium that will reduce the wear that is caused by relative motion between the parts. I am looking for any advice!

Are the parts alkaline anodized, Genevieve? That's usually the basic first step in addressing a problem like this.

Try nitriding the titanium - it gives a good gold colour with very high hardness.

Try boron nitride which is even harder than titanium nitride. In a final step I would apply Teflon.
