Efeito da oxidação nas análises de dureza e atrito em filmes finos de Si3N4
(2014-06-23)
Hard coatings are widely used in surface engineering of mechanical components due to
their high wear resistance and reduced friction coefficients. Actually, the dry cutting techniques
are demanding new materials with ...
