Toxicity of tungsten, cobalt and titanium carbides

[amikee]

I am trying to do a research on carbidizing titanium blades and can't find my answer anywhere.
Can anyone chime in with some info?
Is there any risks for using any of those?
Thank you

Depends on what do you mean by using it.
Inhaling volatile heavy metal compounds while carbidizing is not good, but using such blade is safe.

I meant after it's electroplated onto titanium or whatever steel.
Inhaling dust it's not good, right. But does any of it stay in the food when a knife is carbidized? I'm very curious although probably it safe like you're saying. Otherwise people wouldn't make them and use them. Thank you

No, it isn't really transferable in use.

Thank you for the information Stacy.
