STUDY OF THE EFFECT OF TEMPERATURE ON THE HARDNESS, GRAIN SIZE, AND YIELD IN ELECTRODEPOSITION OF CHROMIUM ON 1045 STEEL

A study was made on the effect of temperature on the electrodeposition of hard chromium on 1045 steel within a range of 30° to 60°C, as shown by variations in reaction yield, surface hardness, and depositional grain size. Increase in temperature produced a decrease in faradic yield of the reaction o...
