Corrosion Mechanisms

Abstract Gas turbine engines are susceptible to high temperature corrosion which is enhanced by marine atmospheres. This high temperature corrosion is also known as sulfidation because it is believed that the formation of metal sulfides from sulfur containing substances is essential. An understanding of the corrosion mechanisms involved is necessary in seeking methods of eliminating the problem, and the initial step in formulating mechanisms is to identify the chemical reactions involved. Corrosion product characterization is essential for this identification. Characterization of the corrosion products from the nickel-sodium sulfate-air system at temperatures near 1000 C (1832 F) suggests that the sodium sulfate acts as a flux rather than as a chemical reactant. Some of the techniques used to characterize the corrosion products are discussed.

Abstract The nickel-iron-chromium (alloy 20) is enriching by hybrid surface treatment through plasma nitride (PN) and physical vapor deposition (PVD) process. The plasma nitriding process takes 12 hours at 500°C. Potentiodynamic testing is used to characterize the corrosion performance of the treated material, followed by morphological analysis of the exposed surface; XRD, EDX, SEM, hardness, and tensile testing are used to investigate appropriate coating properties. Plasma nitride and hybrid PVD nickel-iron-chromium alloys exhibit perlite (γ + α ’) phases and martensite (γ + α) phases, respectively. The martensite microstructure ensures superior tensile strength and hardness. The pin-on-disc tribometer test proposes to analyze friction and hard-faced behavior in the dry sliding position. The inclusion of Si improves the adherent oxide film, resulting in a low wear rate in TiAlSiN alloy 20. Due to the presence of the passive film, TiAlSiN alloy 20 exposes the most passive region to attain better corrosion resistance.
