The gear teeth snapping was one of our main concerns and we would never have used worm gears if they didn't back drive.
As for getting the worm gear in a harder material the only other material that they're made in is cast iron and while thats harder it's also brittle and won't help at all with the teeth snapping issue.
One other comment on the design, you're going to want thrust bearings on both sides of the worm.

I brought up a few of the several concerns
here, but I don't have experience with worm gearing for drive parts. My thought is that the teeth will just snap off before the wheel looses traction with the ground. In your gearbox, did you have your worm gear before or after any other reduction?
