INFLUENCE OF SURFACE ROUGHNESS AND PREOXIDATION STATE ON THE WETTABILITY OF ALUMINIUM NITRIDE BY COMMERCIAL BRAZES
Aluminium nitride substrates were prepared with surface finishes (Ra) of 0.17-0.20 micron and 0.02-0.03 micron and annealed in vacuum at 800 C. The smoother samples were oxidised in air at 1250 C. The wettability of the prepared surfaces by commercial brazing alloys CB4 (70.5%Ag, 26.5%Cu, 3%Ti) and...
