Al 9Si 6BN 20Polyester Powder Description:
Al 9Si 6BN 20Polyester Powder coatings are tailored for aerospace and industrial turbine applications, specifically engineered to optimize clearance control and enhance operational efficiency. These coatings belong to the class of Titanium blade-friendly abradables, meaning they can be cut by untreated titanium alloy blade tips. Composed of an Al12Si metallic matrix with embedded polyester, they offer excellent rub characteristics and strike an optimal balance between abradability, erosion resistance, and hardness. Designed to meet stringent gas turbine OEM specifications, these coatings have a proven track record globally. Best applied via the atmospheric plasma spray process, they find application in lightweight clearance control coatings for aerospace turbine engine low-pressure compressors and automotive/industrial turbochargers. Compatible with a range of blade materials including untipped titanium alloy, nickel alloy, and steel, they ensure minimal wear to rotating components while maximizing gas path efficiency in seal areas.
