Electrical conductivity properties of WC Co

[Met.Eng.]

Hi every one,

We want to make high wear resistance and tolerable low electrical conductivity surface characteristic.


Does anyone have information about the electrical properties of WC-alloys? (WC-Co, WC-CoCr, WC-Ni...ect.)

Besides, If we make a comparison between WC alloys to TiC alloys, which one do you think we must choose? (low electric conductivity).

I would be happy if the type of proposal other than oxide ceramics tiles.

Thank you very much for your answers. Good day everyone.

Hi Metallurgy_eng

Depends what a "tolerable low electrical conductivity surface characteristic" actual is. If you are after an insulator with high wear resistance, I think you will need to consider oxide ceramic coatings. Cermet coatings, though probably being more resistive than metal coatings will still tend to be quite conductive.
