Suitability of Novel Titanium Powder for Metal Injection Moulding Application

Abstract:

A new technology of titanium metal powder production by means of two stages reduction of titanium dioxide, using magnesium and calcium, has been developed and patented by VELTA, Ukraine. In addition to the grades of pure metal titanium, the proposed technological scheme makes it possible to obtain various titanium alloys powders by joint reduction of titanium dioxide with oxides of alloying elements. The powder consists of compact particles with a low content of interstitial elements oxygen, nitrogen and carbon under the levels of standard for Ti Grade 1. A particle size measurement shows a broad distribution with D50 near 50 µm with a large number of very fine, almost spherical particles under 2 µm. A classification of the produced powder by a relatively cheap sieving technology into fractions makes it suitable for different powder metallurgical applications, particularly in Metal Injection Moulding (MIM) technology. The fraction of the powder under 45 µm (35 wt.% of the product) has been tested for MIM technology. Two types of feedstock (catalytic and water-soluble) were used in the study. Sintered samples comply with Ti-400 standard for MIM components used in medical, chemical, aerospace and other industries.
