Role of Sintered Porous Metal Filte

Fluid Filtration

Porosity is capable of retaining solid particles contained in liquid or gaseous fluids and partially separating liquid and solid phases or gaseous phases of different molecular weights. This property can be used to filter a variety of fluids with different characteristics.

Pressure drop

Porosity reduces the pressure of the fluid passing through it, a phenomenon known as pressure loss. This phenomenon is used to suppress the sound of pressurized gases (silencers) or to protect hydraulic equipment and electronic devices.

Flow control

Porosity allows the fluid to pass through it with a constant flow rate at the outlet of the porous member, especially when the flow is generated by capillaries. In this way, a precise control of the output flow of the fluid stored under pressure is achieved.

Air / Fluidization

The passage of pressurized gas through porosity results in a constant, controlled gas flow rate at the outlet of the porous component, with the same pressure distribution at all points. In this way, liquids can be vaporized or aerated, providing a constant gas flow rate, or powdered solids can be manipulated by fluidization.

Moisture Resistance

Porosity is capable of retaining and condensing moisture in the gas passing through it. This property is used to dry and protect equipment from corrosion.

What are the design considerations for a sintered metal filter?

When selecting a sintered metal filter, consider the required particle retention, the flow rate through the filter, the operating fluid, and more. Our last blog post on filter design considerations focused on specific applications, such as fuel filters and hydraulic oil filters in industries such as aerospace, defense and marine. When considering sintered metal filters more specifically, you'll want to know the following additional points.

Pore Size - Also known as micron rating, pore size defines the size of particles you want to block. If a filter is rated at 5 microns "absolute", this means that 99% of particles larger than 5 microns in size will be blocked. If you specify a "nominal" rating of 5 microns, you are allowing a much larger percentage of 5 micron particles to pass, perhaps as much as 60%.

Pressure Drop - This is the pressure loss that occurs as the liquid or gas flows through the filter. You must determine how much pressure your specific application will allow and specify this to the filter manufacturer.

Temperature Range - How hot or cold your filter will operate. The metal alloy you choose for your filter must be able to tolerate it.

Strength - Sintered filters are a good choice when high strength is required. Another advantage is that they provide the same level of strength in forward or reverse flow.

Please contact us to share your requirements!

Please see the previous section on design considerations. Before ordering a sintered metal filter, you need to thoroughly understand your application. The following questions need to be answered prior to fabricating a mold for a sintered filter.

What is the application? (e.g., filtration, fluidization, dispersion of gases in liquids, noise abatement, extraction of oil or other liquids from gases, )

What will pass through the filter?

What is the corrosion problem?

What special operating conditions, such as temperature or pressure, are involved?

What contaminants may be encountered?

What sizes, shapes and tolerances are required?

How many units will be required?

How will the filter be mounted or supported?

What is the ideal flow rate and allowable pressure drop across the filter unit?

What is the overall pressure of the system?

With the answers to the above questions our professional engineers will be able to answer any questions you may have! (Estimates?, technical?, advice?, etc.)

For years, materials scientists and engineers have been trying to create porous metals and metal foams based on in an attempt to emulate naturally porous materials, such as bone, coral and cork.

Metal foam is a cellular structure made up of a solid metal containing a large volume fraction of gas-filled pores. These pores can either be sealed (closed-cell foam), or they can be an interconnected network (open-cell foam). The closed-cell foam is referred to as metal foams, while the open-cell foam is referred to simply as porous metal.

Metals that Can Be Used

The metal that is commonly used to make metal foams is aluminium. However, other  varieties of metals can be used to make the foam, such as titanium and tantalum.

Properties of Metal Foam

The key properties of metal foam are as follows:

• Ultralight material (75&#;95% of the volume consists of void spaces)
• Very high porosity
• High compression strengths combined with good energy absorption characteristics
• Thermal conductivity is low
• High strength

Metal Foam - Science Nation

Production Method

Metallic melts can be foamed by creating gas bubbles in the liquid. These gas bubbles in the metallic melt tend to rise to the surface due to the high buoyancy forces in the high-density liquid. In order to prevent this from happening, the viscosity of the molten metal has to be increased. This can be done by adding fine ceramic powders or alloying elements to form stabilizing particles in the melt.

Three ways of foaming metallic melts are listed below:

• Injecting gas into the liquid metal from an external source
• Causing the precipitation of gas that had just been dissolved in the liquid
• Causing an in-situ gas formation in the liquid by admixing gas-releasing blowing agents to the melt

Foaming of Metallic Melts using Gas Injection

Foaming aluminium and aluminium alloys is used by Cymat Aluminium Corporation in Canada and Hydro Aluminium in Norway. Silicon carbide, aluminium oxide, or magnesium oxide particles can be used to enhance the viscosity of the melt.

The mixing techniques should be consistent to ensure uniform distribution of particles throughout the melt. The melt is then foamed by injecting gases, namely, air, nitrogen, and argon into it using rotating impellers or vibrating nozzles.

Foaming of Melts with Blowing Agents

A second method for foaming melts directly is to add a blowing agent to the melt instead of injecting gas into it. Gas is introduced into the melt by using compounds such as hydrides or carbonates.

The compound tends to decompose and forms gas bubbles when heated in a liquid metal or semi-solid pellet. The resulting foam has to be stable so that the porous metals will have uniform pore sizes and densities.

Shinko Wire Company, Amagasaki, Japan, has been producing foams using this method. About 1.5 wt.% calcium metal is added to an aluminium melt at 680°C (F°). The melt is mixed well and the viscosity starts to increase due to the formation of calcium oxide, calcium aluminum oxide, or Al4Ca intermetallics. This aids in thickening of the liquid metal.

Once the viscosity reaches the desired value, titanium hydride as a blowing agent is added serving to release hydrogen gas in the hot viscous liquid. The melt then begins to expand slowly and gradually, filling the foaming vessel. The foaming has to take place at constant pressure. When the vessel is cooled below the melting point of the alloy, the liquid foam turns into solid aluminium foam and can be taken out of the mold for further processing.

Solid-Gas Eutectic Solidification

Porous materials formed by solid-gas eutectic solidification are called &#;gasar&#;, meaning &#;gas-reinforced.&#; It has been a known fact that certain liquid metals form a eutectic system with hydrogen gas.

When one of these metals is melted in a hydrogen atmosphere under high pressure of up to 50 atm, the resultant melt is homogeneous and charged with hydrogen. The melt will have a eutectic transition to a heterogeneous solid+gas system when the temperature is lowered. The solid+gas system should have a eutectic concentration, and then a segregation reaction will occur at a specific temperature.

The melt begins to solidify causing gas pores to precipitate and become entrapped in the metal. Mostly elongated pores oriented in the direction of solidification are formed.

Applications

The main applications of metal foams and porous metals are listed below:

• The closed variety is used for structural applications requiring load-bearing features, and for weight-saving and impact-absorbing structures in vehicles
• The open variety is ideal for vibration and sound absorption, filtration and catalysis at high temperatures, for heat exchange and in medical devices.
• The open variety is also useful in functional applications such as filtration and damping.
• Foam metal is being used as an experimental prosthetic in animals.
• Metal foams with high strengths can act as high-capacity impact-energy absorbers.
• Automotive industry - the foams reduce the number of parts in the car frame, facilitate assembly, thereby reducing costs and improving performance.
