CO5811 Co 25Cr 5Al 0.27Y 1.75Si 15HBN Powder

Co 25Cr 5Al 0.27Y 1.75Si 15HBN Powder Description:

Co 25Cr 5Al 0.27Y 1.75Si 15HBN Powder is a specialised cermet mixture composed of a CoCrAlYSi alloy and hexagonal boron nitride (hBN), developed for thermal spray coatings that provide exceptional protection against metal-to-metal wear on components made of titanium alloys. This powder is particularly effective in applications where only one surface can be coated due to space constraints, such as in the dovetail attachment of compressor blades to discs. High-strength coatings with low hBN content can be applied using the High Velocity Oxygen Fuel (HVOF) process. In contrast, coatings with lower strength and high hBN content are suitable for Atmospheric Plasma Spray (APS). Coatings produced from this powder have demonstrated superior performance at temperatures up to 450°C (840°F), significantly surpassing CuNiIn coatings in terms of friction coefficient, disc wear and pit depth. These coatings exhibit high compressive strength and are therefore suitable for compressor blades of all sizes, including large blades used in fans and low-pressure compressors. Each application should be validated under conditions closely resembling actual service conditions.
