Carbidized Edges

I have some Mission knives, straight and folding, that utilize beta hardened Titanium blades. I have some Boker kitchen knives of the same material. I had one of the Bokers Carbidized with a Titanium Carbide electrode after I chisel sharpened it. It was Carbidized on the non-bevel side.
I also have some Boker Cera-Titan knives, straight and folding, that utilize Titanium blades to which Titanium Carbide and Silver were added to improve the wear resistance and ductility. The Cera-Titan knives hold an edge like a ceramic blade but will not shatter when dropped.
I like all of my Titanium blades.
 
Just thought I'd add 2 cents to an old thread while investigating carbidized blades on the interwebs. I've also seen random RC numbers regarding Ti grades 5 and otherwise, and I believe this is due to 2 things: The first is who made it? Metals can get dirty and not be exactly what they're supposed to be, i.e. when I took my welding exams i could only use USA made steels because the Chinese stuff gets wonky and can ruin your tests. And secondly, grade 5 and it's improved ELI grade 23 will work harden, along with Beta titanium, increasing this number. That's why they forge plane parts, it's stronger. The stuff can be impressive, it's not like we knew how to make a good steel blade (or steel for that matter) without decades of ingenuity and hard work. Carbidizing is another way to get a specific improvement out of metals and now that I know how to make a carbidizer I'm about to have a little fun! :D I'd like to thank you guys for these posts as it has been enlightening.
 
I have been following this thread,nice to see a post here.
I built one of these(link below) and have just tested on titanium scrap but it seems to work.
I might try to carbidize a lock face in the near future.
