Aircraft Turbines
Large fan blades or small compressor blades – the variety of blades used in aircraft engines is huge. The examples given here are only a selection of different shapes and materials. Nickel-based high-temperature alloys and titanium alloys have, for years now, been important components in the aviation industry.
The development of nickel alloys, titanium and titanium alloys is closely linked to the aviation sector. Nickel alloys are a major factor contributing to the efficiency of aircraft, especially in aircraft engine construction. Semifinished products such as rods, discs, panels, blades and forged parts are used in medium and high pressure compressors, where high strength and high-temperature stability are indispensable requirements. The main alloying element of most superalloys is either nickel or cobalt. Stability at high temperatures, high creep strength, good fatigue performance, low crack propagation, toughness and resistance to high-temperature oxidation are, therefore, the key properties and features of these superalloys. After superalloys have been melted, they are often re-melted twice to meet the highly stringent quality requirements of the aerospace industry, and to ensure the high purity of the material, microstructure homogeneity and an exact chemical analysis. Some components, where low weight is equally as important as high strength, are made from titanium alloys, which are designed to exhibit exceptional strength and corrosion resistance during use under high and critical stresses.
A perfect surface finish is therefore of elementary importance. To find the right abrasives for your finishing application on new or repaired components, such as vanes, blades, honeycomb seals and housings, compare our products in our "Turbines" brochure.
