NASA / TM-2010-216233 Thermal Expansion of Vacuum Plasma Sprayed Coatings

Metallic Cu-8%Cr, Cu-26%Cr, Cu-8%Cr-1%Al, NiAI and NiCrAlY monolithic coatings were fabricated by vacuum plasma spray deposition processes for thermal expansion property measurements between 293 and 1223 K. The corrected thermal expansion, (AL/Lo)therma1, Varies with the absolute temperature, T, as (AL/L.o)the.a1= A(T – 293) 3 + B(T – 293)2 + C(T – 293) + D… CONTINUE READING
