Abstract
The article deals with the application of PVD (Physical Vapour Deposition) coatings onto the surface of compressor blades. In sandy or dusty conditions, compressor blades are the first obstacle for particles which are being sucked into the jet engine. Compressor blades equipped with a protective layer should have greater resistance against erosive and abrasive damage. To support this theory, an empirical experiment had to be conducted. Based on the data acquired from the experiment, we were able to summarise the effectiveness of coatings applied.
Highlights
The gas turbine engines operate in one of the harshest environments, which enforces the continuous development of the applied materials
If we look at this problem from a purely theoretical point of view, the coating applied to the blade surface should increase its lifetime
It would be possible to implement this technology for military aircraft, either turboprop (C130, C295W, C-27J, etc.) or turbojet (C17, A330 MRTT, KC390, etc.) which operate from unpaved runways
Summary
The gas turbine engines operate in one of the harshest environments, which enforces the continuous development of the applied materials. The main objective of this article is to show the possibility of protecting the compressor blades with PVD (Physical Vapour Deposition) coating, prolonging their lifetime These coatings are implemented onto the desired object in order to improve its resistance to wear, drag, abrasion and erosion. The process of erosive wear of components and entire sub-assemblies of the aircraft gas-turbine engines may have a fundamental impact on their durability and reliability level. This is especially important when one realizes that quartz grains are characterized by hardness equal to 7 in the 10-degree Mohs scale, and diamonds being equal to 10. The second one occurs when dust particles, under the influence of inertia forces, strike their operating surface, which is characteristic for wear of the initial stages of the compressor’s rotors [5]
