Corrosion inhibitor solutions and corrosion-resistant substrates that include pyridinium hydroxyl alkyl ether compounds and methods of making the same

A method of producing a corrosion-resistant substrate, the method comprising:

• contacting at least a portion of a first surface of a substrate with a corrosion inhibitor solution, wherein the corrosion inhibitor solution comprises a solvent and a pyridinium hydroxyl alkyl ether compound having a general formula:
• wherein R1 is a C1-C18 alkyl group, a C1-C18 hydroxyl alkyl group, a C1-C18 alkenyl group, a C1-C18 alkynl group, a C1-C18 acryl group, a C1-C18 cycloalkyl group, or a C1-C18 functional alkyl group;
• and
• wherein RA, RB, RC, RD, and RE are each independently chosen from hydrogen, a C1-C18 alkyl group, a C1-C18 hydroxyl alkyl group, a C1-C18 alkenyl group, a C1-C18 alkynl group, a C1-C18 acryl group, a C1-C18 cycloalkyl group, or a C1-C18 functional alkyl group;
• and
• drying the corrosion inhibitor solution to produce the corrosion-resistant film on the substrate, wherein at least a portion of the solvent is expelled from the corrosion inhibitor solution during the drying to form the corrosion-resistant film, such that the corrosion-resistant film is solid.
