DISPERSIóN ASISTIDA POR MAGNETRóN EN PELíCULAS DE TiN

by means of the pvd (physical vapour deposition) technique using magnetron assisted dispersion, a film of tin it was deposited on sustrates of tool grade steel d2, starting from a titanium target in a mixture of ar and n2 gases. the films was deposited at sustrate temperatures around 400oc. a significant surface change in the typical golden color and in the hardness was observed. the results obtained using sem (scanning electron microscope) and diffraction of x rays reveal that there was a change of coloration, composition and hardness when varying the conditions of deposition times and working distances. this was confirmed in the results obtained by hardness measurements using a mitutoyo microdurometer. the scanning electronic microscopy revealed a columnar morphology. vickers hardness measurements were performed on all samples.
