| RADIATOR CORROSION EXPERIMENTS. The following is a list of the tests applied. In all cases tap water was used for making the solutions in which the various materials were immersed, also, in all cases, unless otherwise stated, the said materials were placed in the solutions so that they were not touching, but were connected to one another outside by means of copper wire. The vessels and their contents were raised to 100°C during the day time and allowed to cool over-night. The results given are after one week of this treatment. Test No. Particulars of Test. 1 T50L alloy. 2 Piston Metal. 3 T50L in 0.01% solution Zinc Chloride. 4 Piston Metal as (3). 5 T50L in 0.02% Borax and 0.01% Boric Acid Solution. 6 Piston Metal as 5. 7 T50L in solution 0.02% Borax. 8 Piston Metal as 7. 9 T50L in soln. 0.02% Borax 0.01% Boric Acid and 0.01% Zinc Chloride. 10 Piston Metal as 9. 11 T50L in soln. 0.02% Borax, and 0.01% Zinc Chloride. 12 Piston Metal as 11. 13 T50L in soln. 0.07% Borax, 0.035% Boric Acid and 0.01% Zinc Chloride. 14 Piston Metal as 13. 15 T50L coated with Linseed Oil in soln. 0.01% Zinc Chloride. 16 Piston Metal as 15. 21 T50L in soln. 0.1% Sodium Phosphate. 22 Piston Metal as 21. 23 T50L in soln. 0.01% Zinc Chloride, 0.1% Sod.Phosphate. 24 Piston Metal as 23. | ||
