Forming titanium nitrate on titanium effect electrical resistance




We are thinking about protecting titanium by nitration forming a titanium nitride coating of 4-6 micrometers. Will this effect this effect the electrical resistance.
We want to contact the titanium plate and want a low resistance.

Titanium nitride has a lower electrical resistivity than titanium.

Jim, are you sure? Perhaps you mean a lower electrical conductivity, equivalent to a higher electrical resistivity?

The resistivity of titanium is around 55 micro-ohm-cm; titanium nitride coatings are around 25 micro-ohm-cm. Bottom line: titanium is not a good electrical conductor.

Dear Jim sir,

here I have one doubt can you explain please.

actually Ti is a metal .so it is good conductors of electricity, whereas TiN is ceramic film so it needs to have almost lower electrical conductivity. Because metals are good conductors of electricity as well as heat.here I am thinking that Ti will have lower electrical resistivity . can you explain please.

1. Ceramic materials with covalent bonding are poor electrical conductors. These include most oxides and AlN. TiN and the other transition metal nitrides are primarily metallically bonded. Ionically bonded ceramics (salts) are also good electrical conductors.

2. Ti is a very bad electrical conductor, as metals go.
