The trouble with Wankel wear coatings is there is no way to inspect

over every square inch of the wear surface.

In other words there is no way of controlling the quality.

I bet this is interesting "news" to Mazda, seeing as how they have been
nitriding the side housings and chroming the rotor housing for years
without apparent problem controlling quality...

Paul, your emotional reaction to Mark Burns' letter (perhaps deserved)
is interfering with your ability to make rational statements.

Passionate yes....emotional no.

First you missed a very important point Russell.

"Mazda has built over two million engines with excellent results."

Once you make a few hundred thousand engines and they are in
service for ten years you tend to get confidence in what you
are doing.

Second; nitriding is not a coating. It is a hardening process where
a chemical is actually ingested into the surface of the metal at
high temps.
