Before commencing onto the advantages of using plastics in the world of Science and Medicine, you should know about the various kinds of plastic being utilized in this field Read more

How the Usage of Steel Has Increased in the Aerospace Industry

How the Usage of Steel Has Increased in the Aerospace Industry

It is a well known fact that the environmental conditions of outer space are completely different from that of our planet. This is why durable materials such as steel are used to construct all tools and machinery that are used in outer space.

From space exploratory probes to the tiniest component of a space station, you will find steel everywhere. The reason behind this is that steel is capable of enduring high pressure and temperature and is least susceptible to corrosion as compared to other materials. It is thus, due to the utilization of steel and other metals, that space travel has become possible for humankind.

The Utilization of Steel in the Aerospace Industry

There are various components that are made out of steel in the aerospace industry. Steel is the choice of manufacturers in this regard since it is capable of withstanding very high temperatures and pressure changes which will melt other metals.

The following gives you a precise idea about the uses of steel in the aerospace industry.

  • Steel is used to create components such as jet engines which provide power to rockets and spacecrafts.
  • Given the durability of this metal, steel is also used to construct airframes.
  • Numerous alloys can be made with steel that enhance its properties.
  • The fuel tanks of space rockets are made out of steel. This is so because it does not react chemically with the fuel stored in the tanks.
  • The most crucial component that plays a pivotal role in maintaining the lifespan of the space rocket and also, the lives of the crew; is the heat shield. Made out of solid steel, this heat shield is responsible for tackling the aggressive thermal and pressure changes that the rocket experiences while traversing different layers of the atmosphere.

Plastic is the most high performance substance used in the automobile industry today. Not only is it very light, but it is also as cost efficient as it is light and does not tax the engine. Estimates suggest that you can reduce your fuel consumption by 5-7% if you reduce the weight of your vehicle by 10%. Some of the other features that make this material appealing for automobile manufacturers are:

  • Recyclability
  • Minimal corrosion
  • Freedom to create innovative designs
  • Flexibility in the integration of components
  • Economical
  • Safe

Plasma Driven Surface Treatment

Plasma Driven Surface Treatment

To work with materials and unleash their true potential, almost every industry needs to activate their surface to make them more reactive. The increase in the material’s reactivity makes it easier to work with and allows it to be used more effectively. Plasma is the fourth state of matter and is used in almost all industries as plasma technology is one of the most economical methods of surface treatment.

How does plasma activate surfaces?

Plasma state is achieved when additional energy is added to gaseous ions. When plasma comes into contact with the surfaces of polymers, it alters the surface by attaching functional or polar groups to it. The addition of polar or functional groups makes the materials reactive as these groups easily combine and react with other chemical groups. Once the properties of the material are altered, they can be used for a variety of different purposes.

The activation process primarily uses oxygen as a catalyst; however, some materials can react with plasma in open air, without the need of providing additional oxygen for the reaction.

What are the common types of plasma driven surface treatments?

  • Plasma surface treatments can be used for the following industrial treatments of materials:
  • Plasma Driven Surface Activation: Plasma treatments used to activate surfaces
  • Plasma Cleaning: Plasma is used to clean and prepare surfaces for various manufacturing processes
  • Plasma Coating: During plasma coating, an object is bombarded with plasma to allow a layer of polymers to form over the object.
  • Plasma Bonding: Plasma is used to lower the energy needed to bond two materials together.
  • Plasma Surface Modifications: Plasma treatments can be used to generate new properties of materials by activation, conditioning, and functionalization.
  • Plasma Ashing: Plasma ashing is the removal of carbon from products during manufacturing or cleaning processes.
  • Reactive Ion Etching: In this process, plasma treatments etch the surfaces which have already been treated.
  • Plasma Functionalization: This process improves the functions of materials, especially adhesiveness, bonding, and printing.

What makes plasma ideal for surface treatment?

Plasma is used for treating polymers too.

There are several factors that make plasma ideal for surface treatments. For one, it works on a wide range of materials which means that it can be used on multiple materials for multiple purposes. It also works uniformly on all surfaces and efficiently gives high quality results.

Apart from that, it is cheaper to use, store and maintain and has a fast treatment time, so plasma driven surface treatments are useful in the sense that they work well, and save both time and money.

Uses of Steel in the Medical Industry

Uses of Steel in the Medical Industry

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.

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.

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.
