Paul, you didn't really comment on the potential of the idea.
Do you think it won't work? I know it would be more expensive
than steel, but it shoud still be effective. Using the captured
steel plate would be considered bleeding edge by many. I am
interested in your comment on functionality excepting the
cost of course. Bill Jepson

I am trying to minimize the sharpness of the bleeding edge :)

It might be functional but the first thing you want to do is find
out if the basic idea works so you start with parts of it that you
know will work. It is like experimental science. You only change
one thing at a time. Determining if titanium really worked better
than steel may take thousands of hours of engine time.
I don't see the benefit of the higher conductivity.
What you really want to do is run the steel hotter as that
will minimize the energy loss to the cooling system.

With two cycle oil you can still lube the side seals at even
higher wall temps. We have evidence of that as no wall oil coking
is taking place on the much hotter rotor housing with the current set ups
and two cycle oil apex seal lube.

Bill,
I like the idea but don't know much about the Titanium Nitride process -
does it give a coat that could peel off or does it actually penetrate the
surface of the Titanium and harden that surfacing and to what depth.

I can see the advertising now -wouldn't that blow the socks off the
competitors.
