UK RESEARCH AIMED TO REDUCE MOTOR VEHICLE CORROSION CAUSED BY HIGHWAY DEICING SALT

Occurrence of aggressive attacks on automobiles in regions where deicing salt is used are described and some of the mechanisms and controls discussed. Laboratory tests with various inhibitors, including synergism of two or more inhibitors have produced inconclusive results. On-site tests on vehicles and in outdoor test equipment also have not indicated good results unless phosphates, Ca or Zn are included. Organic inhibitors are sometimes better than phosphates but are more expensive. Track tests in Europe and England are described and economics considered. Advantages of car washing with inhibited water are discussed and various tests and results reported. Track tests indicate that the most damaging corrosive effect--inside out attack--is not substantially reduced by inhibitors. The effects of spray washing with inhibited water are measurable but test results do not reflect what actually happens under service conditions.
