Ni35/AlSi12　double　performance　coatings　were　obtained　through　laser　melting　deposition　technology.　Ni35　alloy　and　AlSi12　powder　produced　significantly　metallurgical　reaction,　resulting　in　precipitation　brittle　NiAl　intermetallic　phases　thus　has　a　higher　cracking　tendency.　And　the　cracks　cannot　be　controlled　effectively　through　the　optimization　of　the　process　parameters.　Therefore,　Ni35/Cu/AlSi12　double　performance　coatings　with　lower　crack　sensitivity　and　higher　metallurgical　quality　obtained　through　laser　cladding　Cu　alloy　buffer　layer.　The　microstructure　of　the　coatings　and　the　interfaces　were　characterized　using　SEM　and　XRD,　respectively.　Additionally,　the　micro-hardness　and　thermal　simulation　of　the　double　performance　material　with　Cu　alloy　buffer　layer　were　analyzed.　The　results　show　that　Cu　alloy　buffer　layer　can　effectively　inhibited　the　formation　of　NiAl　intermetallic　phases　and　reduced　cracking　susceptibility　to　a　certain　extent.　The　Ni35/AlSi12　double　performance　material　with　Cu　alloy　buffer　layer　has　good　mechanical　properties　and　excellent　heat　transfer　characteristics.　©　2015,　Editorial　Office　of　TRANSACTIONS　OF　MATERIALS　AND　HEAT　TREATMENT.　All　right　reserved.
