Abstract

Corrosivity to steel and aluminum alloys on the example of St3, D16T, and D16AT is studied for solutions containing sodium and calcium chlorides in a weight ratio of 3 : 1, and urea in a ratio of 10 to 90% to the NaCl + CaCl2 mixture. It is determined that urea has no noticeable effect on the corrosivity of chlorides to the studied samples of steel and aluminum alloys.
