NK5959 Ni 17.5Cr 5.5Al 2.5Co 0.5YO Powder

Ni 17.5Cr 5.5Al 2.5Co 0.5YO Powder Description:

Ni 17.5Cr 5.5Al 2.5Co 0.5YO Powder is a high-performance composite powder developed for the production of self-bonding coatings with excellent oxidation and corrosion resistance at temperatures up to 980°C (1800°F). The addition of Chromium enhances oxidation resistance, while Aluminium and Cobalt improve self-bonding properties and overcome high residual stresses in nickel-chromium alloys. Yttrium oxide reacts during the spraying process with Aluminium to form a ductile ceramic Al2O3-Y2O3 complex oxide, which increases the high-temperature cohesive strength of the coating and provides flexibility for applications requiring bending.

Ni 17.5Cr 5.5Al 2.5Co 0.5YO Powder Specifications:

Ni 17.5Cr 5.5Al 2.5Co 0.5YO Powder Applications:

1. Protective Barriers: It is utilised as a protective coating in environments exposed to high temperatures and corrosive conditions, such as gas turbines, industrial furnaces, and other industrial high-temperature processes.

2. Bonding Agent for Thermal Barrier Coatings: It serves as a bonding agent for ceramic thermal insulation layers in the aerospace and energy generation industries by improving adhesion of ceramic top coats on metal substrates and providing an intermediary layer that alleviates thermal expansion differences.

3. Oxidation and Corrosion Resistance: The application extends to components exposed to oxidative and corrosive environments, such as turbine blades, combustion liners, and exhaust components in the aerospace and automotive industries.

4. High-Temperature Applications: The powder is suitable for applications where materials are required to maintain their integrity and performance at temperatures up to 980°C (1800°F), such as in heat exchangers and other high-temperature installations.

5. Flexibility-dependent Uses: Due to the formation of a ductile ceramic Al2O3-Y2O3 complex oxide, it is ideal for applications where mechanical flexibility and high-temperature cohesive strength are critical, such as in flexible joints and dynamic components exposed to temperature fluctuations.

Ni 17.5Cr 5.5Al 2.5Co 0.5YO Powder FAQ:

Q1: What are the main advantages of using Ni 17.5Cr 5.5Al 2.5Co 0.5YO Powder for coatings?

A1: The main advantages include excellent oxidation and corrosion resistance at high temperatures (up to 980°C or 1800°F), improved self-bonding properties due to Aluminium and Cobalt, and enhanced high-temperature cohesive strength and flexibility owing to the formation of Al2O3-Y2O3 complex ceramic oxides.

Q2: How does the addition of Yttrium oxide affect the performance of the coating?

A2: Yttrium oxide reacts during the spraying process with Aluminium, forming a ductile Al2O3-Y2O3 ceramic complex oxide. This enhances the high-temperature cohesive strength of the coating and provides flexibility, making it suitable for applications requiring mechanical bendability and resistance to temperature variations.

Q3: What spraying techniques can be used to apply Ni 17.5Cr 5.5Al 2.5Co 0.5YO Powder?

A3: Plasma spraying is the most common technique for applying this powder, as it enables the formation of high-quality, self-bonding coatings with excellent adhesion and uniformity.
