“…The technique described in this paper shows how it is possible to activate the surface layers of the corroded component to chemical and physical attack by introducing, in this case, aluminium by a chemical vapour deposition process (aluminising). This process of aluminising has been well studied and is commonly used to protect turbine components in the hot section of both aero and land based turbines against corrosion and oxidation (Duret et al, 1982). The aluminide coatings used in these cases are typically 25 -75 micron in thickness.…”

During the normal operation of a land based gas turbine attack will occur of the gas washed surfaces of the rotating and stationary blades in the turbine hot section. This attack and its intensity can be variable depending on the blades position in the turbine hot section. This attack will progressively degrade these gas washed surfaces even if these surfaces have been previously coated with a protective layer. During the service period of the turbine, it will be necessary to refurbish the blades from the hotter section of the turbine. One of the refurbishment steps will be to provide the blades with a suitable replacement coating to afford protection until the next service period. Conventional refurbishment techniques used to clean the blade surface rely on abrasive cleaning and/or chemical pickling. These processes may be capable of removing superficial oxidation and any residual coating but are not able to consistently remove the substrate material that has suffered from corrosive attack. It is important that this attacked substrate layer is removed completely otherwise any residual corrosion products, particularly the presence of deeply penetrated sulphides in grain boundaries, could significantly reduce the life of any subsequent coating. The technique described in this Paper essentially activates the surface layer of the substrate that is corroded, thus rendering it more easily removed by chemical and physical means. It is possible by this method to remove up to 400 microns of the substrate material and provided that all the corrosion products are contained within this zone, it is demonstrated how this produces a clean unattacked surface that is necessary for any subsequent welding, brazing or recoating operation.

“…As a result it has been used in Pratt and Whitney commercial aircraft engines [153]. Furthermore, to improve hot corrosion resistance, especially against low-temperature type II corrosion, of the traditional overlay M-Cr-Al-Y coatings, the addition of Pt, Ti, Zr, Hf, Si and Ta [179-181] have been examined.…”

Part III of this overview presents a summary of the potential multifunctional applications of MAX phase materials. Coatings of these materials have been investigated for a range of uses, such as for: high-temperature electrical contacts, microelectronic layers, magnetic and optical materials, fuel holder protection in the nuclear industry, oxidation, corrosion and erosion protection, biocompatible material, thermal barriers, protective aerospace coatings and as armour in defence applications. What makes this material useful for many of these applications is its excellent mechanical properties, damage tolerance, self-healing, high-temperature melting point, and its outstanding oxidation, corrosion and abrasion resistance. Particular attention is given to an aircraft engine's design and the related materials challenges. A comparison is made to the currently utilized turbine surface coatings, as well as the motivation behind the usage of these new high performance MAX phase coatings, the nature of their protection/wear and other strengths/weaknesses.
