The oxygen-enriched alpha case on titanium and alloys was successfully deoxygenated to satisfactory levels by electrolysis in molten CaCl2, in which the cathode was made from the metal to be refined. The oxygen distribution in the metal before and after electrolysis was characterized by microhardness tests, scanning electron microscopy (SEM), and energy-dispersive X-ray (EDX). The electrolysis has been carried out at voltages sufficiently below that for the decomposition of CaCl2, and the… 

Electrochemical Deoxidation of Titanium and Its Alloy Using Molten Magnesium Chloride

Oxygen was directly removed from pure titanium and a Ti-6Al-4V alloy by electrolysis in molten MgCl2 at 1173 K (900 °C), where the metal being refined was the cathode and a graphite rod was used as

Electrochemical Deoxidation of Titanium in Molten MgCl2–YCl3

A new electrochemical deoxidation process for Ti, where a mixture of magnesium chloride and yttrium chloride (MgCl2–YCl3) is used as flux, was developed. In the new process, Ti and carbon were used

Electrochemical Removal of Oxygen in amorphous Zr55Cu30Al10Ni5

Contamination with oxygen is known to reduce the processability and otherwise affect the properties of Zr-based bulk metallic glasses (BMGs). Due to their affinity for oxygen, however, it is

Calciothermic reduction of titanium oxide and in-situ electrolysis in molten CaCl2

A concept for calciothermic direct reduction of titanium dioxide in molten CaCl2 is proposed and experimentally tested. This production process consists of a single cell, where both the

Process strengthening for electrochemical reduction of solid TiO2 to Ti in situ

In this paper, a new electrolysis device was presented with corundum crucible as an electrolytic cell in place of a graphite crucible, and in the corundum crucible a sleeve with a cathode pellet with

Fe‐Ti Alloy Production from Mixed Ilmenite and Titanium Dioxide by Direct Electrolytic Reduction in Molten Calcium Chloride Electrolyte

The electrolytic reduction process of mixed ilmenite (FeTiO3) and titanium dioxide (TiO2) to Fe-Ti intermetallic alloy in molten calcium chloride (CaCl2) electrolyte was studied. FeTiO3 and TiO2



Electrochemical deoxidation of titanium

Removal of oxygen in titanium using an electrochemical technique was examined at temperatures around 1223 K with the purpose of obtaining nearly oxygen-free titanium. Titanium and carbon electrodes,

Cathodic refining in molten salts: Removal of oxygen, sulfur and selenium from static and flowing molten copper

The removal of nonmetallic impurities, including oxygen, sulfur and selenium, from molten copper (cathode) was achieved by constant voltage electrolysis in molten BaCl2 and CaCl2 alone, or the

Direct electrochemical reduction of titanium dioxide to titanium in molten calcium chloride

An electrochemical method for the direct reduction of solid TiO2 is reported, in which the oxygen is ionized, dissolved in a molten salt and discharged at the anode, leaving pure titanium at the cathode.

Electrolytic Reduction of Titanium Monoxide

An electrolytic method for preparation of titanium metal from titanium monoxide is described. The process is carried out in alkaline earth halide melts under an inertatmosphere. The inert atmosphere
