the ebsd technique, in addition to the others methods, confirmed that the welding using brh4-r electrode formed coarser grains than the others samples, less amount of acicular ferrite and also af with lower aspect ratio. among the e-7018 electrodes, it could be observed the coating was responsible to refine the monten zone microstructure
to this end, the magnetron sputtering technique was used to grow trilayered thin films nanostructures of ni 81 fe 19 /cr/ni 81 fe 19, using as substrates al 2 o 3 and zro 2 ceramic flexible sheet produced by the tape casting technique. as a comparison standard, similar films were grown onto amorphous rigid substrate (glass), which has been
experimental. a soda-lime silicate bioactive glass (molar composition: 46.1% of sio 2, 24.4% of na 2 o, 26.9% of cao and 2.6% of p 2 o 5) was used as the bioactive phase of the composite, being therefore the source of bioactivity and responsible for reinforcing the polymer matrix. the glass was used in a particulate form (125-106 µm) and was
