Materials to resist CaCl2 corrosion

Materials to resist CaCl2 corrosion

(OP)
What materials are best suited to resist attack from calcium chloride (CaCl2)? I know that chrome does not.

Temperature and concentration?

Solution or molten salt?

RE: Materials to resist CaCl2 corrosion

A chrome carbide applied by an hvof process would probably work.  The coating is about 98% porosity free if applied correctly and will not allow an attack on the base material.

RE: Materials to resist CaCl2 corrosion

(OP)
I'm not sure of the conditions.  The application is oil-well drilling.  The customer has most of his tools chrome plated, but for the sour wells the calcium chloride eats them away.  It's an inner surface of a narrow bore tube that needs to be coated, so HVOF is out.  We're looking to use a unique inner diameter coating process, but need to determine the best material to deposit.
