Titanium powder preparation and application

Titanium and titanium alloy powder

Titanium powder is a versatile metal powder. Titanium powder is silver-gray irregular powder with high suction power and high temperature, which will produce sparks in flammable conditions. Titanium powder metallurgy (P/M) offers the possibility of manufacturing clean or nearly clean shaped parts without the material losses and costs associated with machining complex parts from forged blanks. The powder can be mixed or pre-alloyed, and then solidified by metal injection molding, hot isostatic pressing, direct powder rolling or laser engineering mesh molding.

Titanium and titanium aluminum alloy have excellent comprehensive properties and are widely used in SLM, EBM, HIP, MIM and other fields. Titanium spherical powder is one of the best metal 3D printing materials and is widely used in the manufacture of high-strength products.

Titanium powder has long been used as an alloy component for various applications. By using it, a net shape part can be created with zero or minimal material loss, which is the same as a complex part of a machine using a blank forging.

Titanium powder preparation

The traditional process for extracting titanium powder is called the Kroll process. This technology requires temperatures as high as 1040°C and involves a series of sub-processes, including alloying, hot isostatic pressing and so on. After that, more methods must be used to produce pre-alloyed titanium powder. In order to remove contaminants, the material must undergo hydride-dihydride process, cold pressing, vacuum hot pressing, final vacuum annealing, plasma rotating electrode process, titanium gas atomization process and plasma atomization. In order to produce the final product, many metal integration strategies must be implemented. Powder injection molding or metal injection molding is a cost-effective and long-term method that can be used to manufacture small-sized metals in large quantities. Then comes the direct powder rolling process for the production of plates. In order to rapidly manufacture, enhance and repair metal parts, laser engineering net shaping technology is applied. In order to compact the titanium powder to its maximum theoretical density, the components must be subjected to hot isostatic pressing, which is carried out under high pressure and high temperature. Finally, in order to obtain the final product, spark plasma sintering or current-assisted sintering is applied to produce titanium powder with better mechanical properties and good grain size without all unwanted grain growth.

The use of titanium powder to print 3D automotive parts is one of the latest breakthroughs in the field of metal manufacturing. It allows 3D printing to produce different parts for automotive and aerospace frames and engines. Titanium powder also plays an important role in metal injection molding and powder metallurgy.

Overview of titanium powder

Titanium powder is a crystalline solid with a gray metallic luster. It is hard in texture, second only to diamond in hardness, and weak in magnetism. The molecular weight is 59.89, the melting point is 3140°C, the boiling point is 4820°C, the relative density is 4.93, and the hardness is 9-10. Insoluble in water, soluble in nitric acid and aqua regia. It is stable to air below 800℃, and corroded by air above 2000℃, at 1150℃. Used in the manufacture of cemented carbide, also used as electrodes and abrasives for arc lamps.

Application of titanium powder

1. Titanium carbide powder is used for high temperature thermal spraying materials, welding materials, hard film materials, military aviation materials, hard alloys and cermets.

2. Used as an additive in thermistor production to improve wear resistance.

3. Titanium carbide powder has a NaCl type cubic crystal structure. Adding 6% to 30% TiC to WC-Co cemented carbide forms a TiC-WC solid solution with WC, which can significantly improve the red heat resistance, wear resistance and oxidation resistance. , Anti-corrosion and other properties, more suitable for processing steel than WC-Co cemented carbide. Alloys such as Ni-Mo can also be used as a bonding agent to form a tungsten-free cemented carbide, which can increase the turning speed and the accuracy and finish of the workpiece.

4. Used as cutting tool materials and additives for metal bismuth, zinc and cadmium smelting crucibles, preparing semiconductor wear-resistant films, HDD large-capacity storage equipment, an important part of cemented carbide, and used as a deoxidizer in the steelmaking industry. It is also used as a cermet, which has the characteristics of high hardness, corrosion resistance and good thermal stability.
