Influence of electric charge of metal on the rate of gas corrosion of titanium VT1-0 and alloy VT6 in carbon tetrachloride
A construction of a chemical reactor with an electric capacitor of a cylindrical type in which the samples investigated are part of the inner liner is proposed. Corrosion rate of commercially pure titanium VT1-0 and titanium alloy VT6 in the low of carbon tetrachloride vapors at a temperature of 673 K and capacitor voltage from 400 to 7680 V with diferent polarity of the electric charge of the inner plate has been measured by gravimetric method. Efect of the electric potential of any polarity applied to the oxidized metal in the capacitor voltage range from 6000 to 7680 V on the gas corrosion rate of titanium in carbon tetrachloride is established. It is shown that the reaction rate of Ti s + CCl4 vap → C s + TiCl4 vap increases by a factor of 2 with increasing the capacitor voltage from 6000 to 7680 V. As the voltage increases, the efect increases. Efect of increasing the rate of oxidation of titanium by the chloroagent can be useful in the processing of titanium scrap.
