Thread: Ceramic coating

I apologize if it has been posted elsewhere, but I build custom woodturning tools and we have been looking into ceramic coating for our tools. I was wondering if there is any reason a razor couldn't be ceramic coated. My thoughts were for minimizing spine wear, rust resistance and looks. A person could even mask parts to decorate. Of course one offs wouldn't be affordable, but if I slip one in with my tools...

It can as long as the temper is not wrecked - But.

A coating can prevent rust over the large surfaces.
The cutting edge is another thing. A normal double
bevel will not expose the coated material as an
edge. Ceramic tends to chip at the angles used
on razors.

If it was easy and worth doing the big guys would be doing
it for their str8's. Does not mean that you cannot
try it with a rescued blade.

So maybe masked behind the proposed bevel? There are many cold applied ceramics as well.

yep the trick would be the temp that the coatign is applyed
but a nice even high gloss black that was rust resistant would be supre cool

might hav eot use a steel like cpm3v cause of the higher tempering temps would hav eot do a bit of trstig on this tho to be sure

Ya I looked into that there are cold applications as well as low heat applications. The low heat could actually be incorporated into tempering process as they are about 400 F IIRC and kept under strict temp/time schedules. I would have to talk to someone more knowledgable about tempering if I choose to go that way.

if they hold 400 for 2 hours or less then i see not mu ch problem on moststeels
