What is the purpose of a surface finish?

The major purpose of a surface finish is to protect and/or decorate the underlying product surface. This can be done by adding material to or removing it from the underlying surface, or by some combination of both methods. When material is added to a surface it is called a coating.

Why the materials selection is important in aerospace components?

Wing design is influenced by strength, durability, and damage-tolerance requirements. Materials properties such as compressive yield strength, stiffness in compression, fatigue resistance, and fracture toughness are key considerations. This is due to ground–air–ground alternat- ing loads generated during flight.

What types of materials are typically used for AM applications in the aerospace industry?

Aerospace industry typically uses premium materials like Titanium alloys, Nickel Alloys, Aluminum alloys and special tools. This is mainly to address the high strength to weight ratio, wide range of operating temperature, high corrosion resistance.

Why surface finish is important in engineering applications?

For many engineering applications, the finish on a surface can have a big effect on the performance and durability of parts. Rough surfaces generally wear more rapidly and have greater friction coefficients than smooth surfaces.

Is higher surface finish smoother?

Overall, the lower the Ra, the higher-purity production application of the vessel. Not only is it easier to clean, but a smoother finish means that it is easier to empty product.

Why is the aerospace industry important?

Aerospace is responsible for many US exports and improvements. Aerospace is important to research because of its lack of publicity. The demand for aerospace-‐related jobs is rising. Aerospace is relied on by many industries (ex: airlines, wireless technology, space travel).

Is aerospace industry an applications of 3D printing?

3D printing is used routinely to manufacture aerospace components that rely on aesthetics over function, such as door handles and light housings to control wheels and full interior dashboard designs.

Why is 3D printing important in aerospace?

3D Printing in Aerospace Airlines depend on 3D printing to alleviate supply chain constraints, limit warehouse space and reduce wasted materials from traditional manufacturing processes. Rapidly producing aircraft parts on demand saves enormous amounts of space, time and money.

What is the product line of the aerospace industry?

The product line of the aerospace industry is, by necessity, broad because its primary products—flight vehicles—require up to millions of individual parts. In addition, many support systems are needed to operate and maintain the vehicles.

What should aerospace and defense professionals know about surface roughness?

With the growing use of advanced ceramics, there are many considerations related to surface roughness that aerospace and defense professionals should understand to ensure that a component is manufactured at a reasonable cost, delivered on-time, and with the ability to perform as designed.

Who are the major customers of the aerospace industry?

In terms of sales, military aircraft have the largest market share, followed by space systems and civil aircraft, with missiles still a modest grouping. The industry’s customers range from private individuals to large corporations and commercial airlines, telecommunications companies, and military and other government agencies.

Why is surface roughness important in the production of ceramic components?

Because the production of critical ceramic components requires a high degree of engineering expertise and manufacturing know-how, the collective abilities of engineers and manufacturers to define, specify, and produce the correct surface roughness for a particular application may determine whether the component will perform to specifications.
