The　adhesion　property　of　Au/NiCr/Ta　multi-layered　metallic　films　was　investigated　by　the　indentation　method,　rolling　contact　fatigue　method　and　scratch　method　with　both　friction　and　acoustic　emission　modes.　The　results　indicate　that　the　indentation　method　can　not　distinguish　if　the　failure　happens　between　the　metallic　film　and　substrate　and　there　are　no　cracks　during　the　indentation　process;　and　the　rolling　contact　fatigue　method　can　not　be　used　to　evaluate　the　adhesion　property　for　metallic　films　due　to　the　plastic　deformation;　only　the　scratch　method　can　eventually　be　used　to　distinguish　the　special　scratch　behavior　for　multi-layered　metallic　films.　Additionally,　the　friction　mode　can　reflect　the　changes　on　different　metallic　film　layers,　it　is　more　sensitive　than　the　acoustic　emission　in　the　same　layer.　The　number　of　layers　and　the　layer　thickness　of　film　and　the　scratch　resistance　of　metallic　films　can　be　reflected　by　a　critical　characteristic　load　at　a　certain　extent.
