INVESTIGATION OF ORGANIC PHOSPHATES AS CORROSION INHIBITORS FOR COOLANTS

Abstract

The object of the study was to investigate the use of organic phosphates as corrosion inhibitors in coolant formulations. Glassware bench corrosion tests and simulated service tests were conducted on various organic acid phosphates in combination with other inhibitors such as sodium tetraborate (borax), sodium metaborate and sodium mercaptobenzothiazole (NACAP). Test data showed that these phosphates when exposed to hard water form non-crystalline precipitates that offer no deleterious effect to cooling systems. Test data also showed that these phosphates are effective corrosion inhibitors when used with a sodium borate buffer.
