Hi all,

This might be a little more scientific question

.

The Talonite is a Cobalt Chromium alloy, right? It has about 28-32% of Chromium, 0,8-1.5% of Carbon, some other elements (not relevant right now) and the balance is Cobalt.

The Chromium is there in form of Chromium Carbides (Cr3C2). The ratio between Cr and C in carbides is about 6.5 to 1. It means that for 1% of Carbon, there should be 6.5% of Chromium. But the Chromium content of Talonite is much higher. Does that mean that there is Chromium in different form? If yes, why? Only carbides actually cut. Can someone explain this?

BTW: I use Talonite knife and regardless of the Chromium content it keeps cutting.....

Great question. Very sophisticated. Apparently you know the chemistry involved so I will address it otherwise.

1. Talonite is chromium and other carbides in a matrix. A big part of the chromium is required for the tough, extremely corrosion resistant matrix that holds the carbide crystals in place.

2. Chromium carbides can be in any of three forms: Cr23C6, Cr7C3, Cr3C2 Talonite may or may not contain just one kind of chromium carbide. This kind of catalytic chemistry and the grain size and overall grain growth technologies are highly proprietary.
 
I know it works and it WONT rust..... thats about all
