Given the crucial nature of their utilization, medical devices should be designed to provide precision at all times. This is of utmost importance. Because the smallest kind of mistake in this field can lead to devastating consequences. In situations primarily governed by retribution claims and lawsuits, all tools that come into contact with the human body or are implanted in it, must be able to deliver flawless performance.
Steel has been used extensively in the medical field since time immemorial. To be specific, stainless steel is the kind of steel that is utilized in the world of medicine. Tt delivers diverse applications, superb finish, and is available in a wide variety of forms.
What Makes Stainless Steel Appealing?
A remarkably high corrosion resistance factor coupled with low carbon content makes stainless steel very appealing in the medical manufacturing industry. This metal provides the assurance that it will not react with any bodily fluid or tissue in case of a surgery or implantation etc.
The Advantages of Steel in Medical Industry
The following are the advantages of using stainless steel:
Diverse set of applications
Reduces risks of any type of infection
Antibacterial in nature as it hinders oxidation
Non-magnetic and so will not cause devices such as a pacemaker to malfunction
It is a well known fact that had it not been for the extensive usage of various kinds of metal, our commercial flights would not have been as durable as they are now, and that fighter jets would not be as efficient at their jobs as they currently are. Given its extra long life and strength, the most reliable material for the construction of any tool or machinery is metallic in nature.
This is the reason that ever since humankind found its way into aeronautics, metal has been extensively used to carry out the design of various items such as overhead bins, propulsive components, navigational tools etc.
The various advantages of using metals in the aerospace industry are:
Extension of the total range of flight
Helps in radar evasion
Increasingly tolerant to harsh chemicals
Increased resistance to radiation
Increased tolerance towards pressure changes
Higher ductility as compared to ceramics and other materials
Excellent electrical conductance
What Are They Used For?
Various components of aircraft’s use metal components. From the body of the aircraft’s to the various navigational tools installed in these planes, metal is found everywhere.
Some of the metals that are the top notch choice in the Aerospace industry are aluminum, nickel, titanium, steel and nickel. These are used to make landing gear parts, critical fasteners, wing components, and hydraulic tubing. These metals also give excellent performance in outer space. We have also found good information about metals and how to treat them on this page http://www.tantec.com/surface-treatment-of-metals.html . But what is equally important, is how these metals are treated, in order to make them so durable. In any case, you will have to treat the surface of the metal, in order to paint it, or to increase adhesion.
The End Note
In today’s world where the economy is volatile, and where you have to keep durability in your mind, using metal is the ideal solution to cut back on the costs of constantly having to construct replacements. Also, using metals makes aircraft’s more durable and safer for travel. This is why this material is a good replacement for the conventional use of metallic alloys.
In a world where the economic situations keep varying with every passing minute, it is difficult to manage one’s fuel costs. In order to cut down on the fuel consumption of vehicles, the automotive manufacturing industry has made various modifications. These are practical measures that have reduced fuel consumption tremendously.
These measures have ensured that the vehicles manufactured, now provide better mileage and cut down on harmful emissions. These modifications have also brought down the amount of wear and tear that the engine experiences; thereby reducing maintenance costs. Read more
Materials with low surface energies like polymers and metals are not wettable by printing ink and adhesives. These materials require some treatment to match the surface tension of adhesives. The procedure of using chemicals, plasma or radiations for increasing the surface tension of non-polar materials is called as surface activation.
Although every method of activation has its own pros and cons, choice of the treatment method depends on the nature of the material being treated. For example, plasma treatment is commonly used to activate the polymer surfaces, while for metal surfaces UV radiations are used.
With the boom of customization and automation in the automotive industry, the need of finely tuned methods for producing high quality automobiles is also increasing. The automotive industry relies on a number of robust preconditioning processes for producing rugged and reliable automobiles. One of such processes is plasma treatment. Although automobile manufacturers have been using plasma treatment in the automotive industry for the surface treatment of automotive parts for years, plasma treatment can also be used for enhancing bonding characteristics of automobile parts.
What is Plasma Treatment?
Plasma refers to the fourth state of matter. According to the principles of chemical reactions, an element can change its state if enough energy is provided. When an element is in the gaseous state, extremely high energy is required to change the state from gas to plasma. Plasma consists of partially ionized atoms which possess high energy. When these excited particles come in contact with a metal surface they transfer their energy to the metal atoms, thus modifying the chemical and physical properties of the material. These modifications in the chemical properties make the material suitable for painting and adhesive bonding. This is the reason that plasma treatment is one of the most commonly used preconditioning processes in the automotive and aircraft industries.
How it Increases Surface Tension?
Automobiles are made of metals and plastic and both of these materials have considerably low surface tension. Low surface tension means less probability that the printing ink or paint will stick to the material surface. Plasma treatment in the automotive industry is used to increase the surface tension of plastic and metals and make them suitable for printing, bonding and painting. Read more
Although plastic can replace metals like aluminum and copper in many appliances due to its light weight, it cannot match the reliability of these metals. One way to improve the reliability of plastic is surface activation. Moreover, the technique can also be used to improve the physical properties of metals like conductivity, immunity to corrosion etc. Every industry relies on this technique for a number of purposes including metalizing, cleaning and improving adhesion.
What is Surface Activation?
Metal or plastic surfaces are treated with different chemicals, plasma or UV rays which energizes molecule and changes the atomic structure of the material up to the depth of few microns. It increases the polarity of the surface being treated thus increasing its wettability. On a commercial scale, surface activation is mostly used to enhance the surface tension of metals and plastics. In automobile, medical devices and aircraft industry, surface activation is used to make the material suitable for printing calibrations and adhesion.
Methods of Surface Activation
While there are a number of ways to treat metal surfaces, some of the most commonly used methods of polymer and metal activation are: Read more
