“…In GTEs, metallic and ceramic coatings, or a combination of both, are usually used to enhance/maintain the system efficiency, thus minimising the maintenance costs [121][122][123][124][125]. It is now generally accepted in the literature that by using coatings in mechanical components, for instance, blades and vanes, the cycle reliability and performance can be protected against the aggressive degradation phenomena, which can cause component failure at an early stage [122,126]. Protection coating is a highly cost-effective technique that helps to increase GTE reliability, availability, and performance.…”

Solid Particle Erosion Behaviour and Protective Coatings for Gas Turbine Compressor Blades—A Review

et al. 2020

View full text Add to dashboard Cite

Gas turbines (GTEs) are often utilised in harsh environments where the GT components, including compressor vanes and rotor blades, are subject to erosion damage by sand and dust particles. For instance, in a desert environment, the rate of damage made by solid particles erosion (SPE) becomes severe, and therefore results in degradation to the GTE parts, lowering the cycle efficiency, reducing the device lifetime, and increasing the overall cost of the operation. As such, understanding the erosion mechanism caused by solid particles and the effects associated with it is crucial for selecting the appropriate countermeasures and maintaining the system performance. This review paper provides a survey of the available studies on SPE effects on GTEs and surface protective coatings. Firstly, the ductile and brittle SPE mechanism is presented, as well as the ductile-brittle transition region. Then, an in-depth focus on the parameters associated with the SPE, such as particles properties and impingement conditions, is introduced. Furthermore, the existing theoretical models are shown and discussed. Afterwards, erosion resistant coating materials for surface protection and their selection criteria are covered in the review. Finally, the gap in knowledge and future research direction in the field of SPE on GTEs are provided.

“…Cr 2 AlC is a member of the ceramics family, has a MAX phase structure, and exhibits excellent properties of thermal and electrical conductivity, thermal shock resistance, machinability, and damage tolerance . These fascinating properties make Cr 2 AlC an optimistic candidate to be used as a protective coating on metallic substrates in harsh environments at high temperatures and high thermal stress . The Cr 2 AlC ceramic coating can be used to protect the Zr clad tube from oxidation at high temperature for the application of nuclear plant security .…”

Surface & Interface Analysis

A diffused interface between a ceramic coating and a metallic substrate is expected to signify a more solid bonding. In addition to depth profiling, a novel 3D view and imaging approach based on ToF‐SIMS analysis was developed to investigate the diffused species around the interface. The diffusion of Al species in a Cr2AlC ceramic coating and Zircaloy substrate system was investigated in both the as‐deposited and postannealed states. In terms of the 3D view and imaging of CsAl+ after Gaussian convolution, Al species visibly diffused into the substrate after annealing at 800°C for only 5 minutes compared with that in the as‐deposited sample.

“…It results in material loss on the surface due to particles in the flowing media generally air. Various of parts of aero engines [2] experience high erosive wear due to dust particles and salt crystals in air which comes along with the air stream during operation. To improve the resistance towards erosion, various researchers are providing solutions such as coating of the surfaces with hard reinforcements, metal matrix composites with ceramic reinforcements [3] etc.…”

In the present study, solid particle erosion behaviour on copper – fly ash composite is studied. Composite with addition of 2.5 (wt.%) fly ash as reinforcement is prepared through powder metallurgy(P/M) technique. Solid particle erosion studies were carried out by varying the input parameters such as erodent velocity and erosion time. The results revealed that addition of fly ash reduced the resistance to erosion.
