THE DEVELOPMENT OF A CORROSION INHIBITOR FOR ADDITION TO ROAD DE-ICING SALT

A CORROSION INHIBITOR FOR USE AS AN ADDITIVE TO HIGHWAY DE-ICING SALT HAS BEEN DEVELOPED. LABORATORY EXPERIMENTS HAVE BEEN USED AS SCREENING TESTS AND THE MORE PROMISING MATERIALS HAVE BEEN EVALUATED IN TRIALS ON CARS. THE CORROSIVE ACTION OF SALT ON MILD STEEL IS ALMOST CONSTANT OVER A CONCENTRATION RANGE OF 10 TO 0.05 PER CENT OF SALT IN SOLUTION. THE PROTECTION GIVEN BY INHIBITORS DIMINISHES MARKEDLY AS THEY BECOME DILUTED AND THEY ARE ONLY EFFECTIVE IN REDUCING CORROSION IF THEIR INITIAL ADDITION IS OF THE ORDER OF 7 PER CENT OF SALT. THIS HAS BEEN DEMONSTRATED BOTH IN LABORATORY TESTS AND IN FIELD TRIALS. /AUTHOR/
