Surface hardening for Titanium and Aluminum.

Carlos · #1

With the ATR and no doubt eventually other titanium-handled knives down the road, I thought that I would mention a couple of ways to protect this soft metal from cosmetic damage.

Ventura, a watch company in Switzerland, uses Nitrogen surface hardening on its titanium-cased watches, bringing the surface hardness to 1300 HV (Vicker's scale). I know of a few people with these watches and all have yet to report a single scratch.

But even better (possibly) is the Keronite surface hardening method for Ti, Al, and Mg. "KERONITE is a process of refractory ceramic oxide layers formation by oxidation of substrate material caused by high-current electro-chemical reactions in electrolyte." Gobbeldygook aside, it results in a ceramic layer on the metal with a hardness of 1300 to 2000 HV. As a final step, it may give Almite, Tufram, etc. a run for their money.

Here is their webaddress so you can look them up yourself:

BTW, the Keronite coating also works with MMC!

Thanx again Carlos. The Tekno place is sure to become my favorite "job" to moderate.

Hi Sal,

It's nice to have someone around who not only likes this high-tech materials stuff as much as I do, but who may actually use it as well. <img src="smile.gif" width=15 height=15 align=middle>
