A chromium layer was deposited on the graphite surface by sputtering and controlled heat treatments were employed in order to develop a suitable microstructure. Scanning electron microscopy measurements showed rough, crack-free interfaces between the filler metal and both the graphite and nimonic parts. From metallographic examination a well defined layered structure of the metallic elements close to the filler/graphite interface has been found. The metallic elements transport from the interface to the carbon bulk where they fill all the graphite pores up to a depth up of 50 μrn and form a layered structure within the pores.5enginfo:eu-repo/semantics/restrictedAccessconference output10.4028/3-908454-01-8.209BrazingChromium carbideGraphiteNimonic alloysGeneral Engineeringhttp://www.scopus.com/inward/record.url?scp=71949083076&partnerID=8YFLogxK
