In a recent effort, AlSi 20wt% BN powder was optimized for clearance control applications in aircraft engines. This paper follows up on the initial results, reviewing the wear mechanism of AlSi, the corrosion behavior of AlSi-BN and AlSi-graphite, and the commercial use of AlSi-BN abradable coatings. Paper includes a German-language abstract.
