Using VPr11-40N Brazing Powder as a Wear-Resistant Cladding for GTE Blade Airfoils

Abstract:

This paper dwells upon using the VPr11-40N high-temperature brazing powder as a cladding applied by a laser to restore the height of the airfoil of a turbostarter blade in an NK-12MP turboprop, while also making the edge more wear-resistant. It has been found out that laser cladding generates a highly homogeneous structure with lesser gradient of hardness over the clad area compared to furnace brazing. Abrasive-wear tests have shown that this braze resists abrasive wear better than the blade substrate material (superalloy JS6К heat-resistant intermetallic alloy).
