A sintered titanium is a pure or alloy titanium that has been subjected to the process of powder classification, molding, and sintering.
Sintered titanium filter
There are several commercial pure grades and alloys of titanium available for use in diverse industries and applications.
They include:
Titanium grade 1 is a pure commercial titanium grade with excellent formability, high impact toughness, and corrosion resistance.
This grade is the most ductile and softest of the titanium grades and is widely used in applications demanding high formability.
Commonly nicknamed the 'workhorse' of pure titanium, this grade is widely available and suitable for many applications.
It closely resembles grade 1 in properties but is much more robust.
Consequently, grade 2 has excellent cold-forming property and moderate strength.
Similarly, it has excellent weldability, ductility, and resistance to oxidation and corrosion.
This grade of commercially pure titanium has a higher strength than the first and second grades of commercially pure titanium.
It also has greater mechanicals than the early two grades.
It is slightly less formable but shares similar ductility levels as the predecessors.
You can use this grade in industries like aerospace and industrial processing that demand high resistance to corrosion and moderate strength.
Similar to other grades, grade 3 pure commercial titanium is available in numerous diverse forms.
It Is the strongest of the four commercial-grade pure titanium.
You can easily cold form it in addition to possessing excellent weldability and resistance to corrosion.
You can use grade 4 for a wide variety of applications though it is best suited for medical-grade titanium, where high-strength materials are fundamental.
Grade 7 is a titanium alloy formed after the addition of interstitial element palladium.
It has similar physical and mechanical properties as grade 2 but with enhanced corrosive resistance, especially reducing acids, making it the most resistant titanium alloy.
Besides, it also has excellent fabricability and weldability.
Because of its strong resistance to corrosion, this grade is suitable for processing chemicals and producing production equipment components.
It is an alloy formed following the addition of trace amounts of palladium to enhance its corrosive properties.
It closely resembles grade 1 titanium but with increased resistance to corrosion.
You can use this product in chloride environments where reducing acids and crevice erosion is a significant concern.
It is the most used titanium alloy accounting for half of the total worldwide titanium consumption.
It has numerous benefits, including:
Grade 23 is a highly pure version of grade 5 and shows superior tolerance to damages compared to other alloys.
You will select this grade if you need a combination of great anti-corrosion, high toughness, excellent strength, and lightweight.
It is widely used in the manufacture of dental and medical-grade equipment.
This grade of titanium alloy has a perfect rating for quality weldability.
It has the following key features:
Possess great strength, creep and corrosion resistance, weldability, and stability at high temperatures.
Other alloy grades of titanium include:
Titanium is a naturally occurring element on the earth's crust and is also the seventh most abundant of naturally occurring metals.
You will readily find titanium as sediments derived from igneous rocks or as titanium oxides.
This metal also occurs naturally in water bodies and living things.
Some of the most common minerals containing titanium include rutile, perovskite, brookite, titanite, and anatase.
However, only two of these minerals, ilmenite, and rutile, are of economic importance though you can rarely get them in sufficiently high concentration.
The naturally occurring titanium comprises five stable isotopes ranging from 46Ti to 50Ti, and isotope 48Ti is the most naturally abundant isotope.
Sintered titanium possess the following key features:
Sintered titanium disc
You should consider using sintered titanium when your application is operating under the following conditions or in the presence of corrosive substances:
The sintered titanium will develop a thick and adhesive film of inert oxides over the material's surface.
The film protects the sintered titanium against corrosion by passivation, enabling you to efficiently filter strong corrosive substances.
Sintered titanium is the most resistant metal against seawater corrosion.
It is also light in weight and has exceptional mechanical strength, making it suitable for high-speed and stationary seawater operations.
It has exceptional filtration abilities for other acid-base fluids.
There are diverse methods of material sintering. Some of the standard techniques include:
Direct metal laser sintering is a 3D technology that utilizes software guidance to melt the powder metal at the sintering temperature. It guides the laser as directed by the cross-sectional software model.
This process repeats itself several times while printing the powder metal layer by layer to completion. This technology has the following benefits compared to traditional sintering methods:
You can produce near pore-free Blended elemental sintered titanium parts through sintering titanium hydride (TiH2) powder instead of the titanium powder. A rise in temperature to moderate levels will dehydrogenate TiH2 before getting sintered at a higher temperature in the vacuum.
Alternatively, you can subject the TiH2 to sinter under controlled atmospheric partial pressure then transform the material by eutectoid. You can then apply a moderate temperature to achieve dehydration. This process is cheaper, produces near pore-free material with ultrafine grain sizes.
It also has superior tensile and fatigue features compared to traditional sintering methods.
You can produce titanium powder either through the following routes/methods.
Initially, you will extract titanium from the natural ore through chlorination then reduce the chlorides using magnesium or sodium. Titanium sponge result as a result of the reduction process. You can also distill the produced sponge in a vacuum for the removal of residual chlorine.
Melt and re-solidify for the formation of got. You can also crush the sponge to form the powder. However, you have to hydrogenate to crush it, given that titanium is very ductile. Subject the product to vacuum heat treatment for dehydrogenation.
The process is helpful where you need to create a product with higher purity levels. Using a feedstock with lower oxygen levels, nitrogen and chlorine, apply hydrogenation to form brittle TiH2. Crush it into a powder then reheat in a vacuum for dehydrogenation and formation of powdered titanium powder.
You can use this method for the preparation of spherical powders. You can use it to prepare commercially pure or alloyed titanium powder. The feed material, a consumable electrode, is a metal bar that is either pure or alloyed.
Working in an inert atmosphere, spun the bar at a very high speed while melting its end by gas plasma arc. The process produces small metal droplets that fly away from the melting end and form spherical titanium powder.
This process utilizes wire as the feedstock for the production of spherical titanium powder. Using this process, you can either produce pure or alloyed titanium or even a titanium aluminide composition. This process has a faster cooling rate compared to PREP. It also produces finer powdered particles compared to PREP.
Other titanium production processes include:
Sintered titanium is exceptionally resistant to corrosion and highly suitable for constructing filters for use under alkaline and acidic environments. You can use either bright titanium. Black titanium constitutes pure titanium wire coated using graphite and is highly suitable for filtration in seawater or ship applications.
On the other hand, bright titanium lacks the graphite coating but has a pure woven titanium wire underneath. You can use this type of titanium to construct fine chemical filters, electrode nets, battery collecting nets, etc.
Generally, you can use sintered titanium in diverse industries demanding strong resistance to chemicals with excellent formability. Specifically, the sintered titanium filter in the following industries:
You can use it for:
Sintered titanium
There are several characteristics of titanium powder, which can significantly influence sintered powder product's characteristics and performance. Such factors include:
Shape and size of powder as a result of the production process. Different powder production methods can deliver either spherical, sponge, or angular-shaped titanium powder.
The powder chemistry can be defined in terms of content impurities. Impurities such as magnesium and hydrogen can arise from the powder production process while others originate from the source. Other common contaminants include nitrogen, oxygen, carbon, sodium, chlorides, etc.
