摘要：

Direct　laser　fusion　bonding　process　of　borosilicate　glass　and　Kovar　alloy　was　investigated　to　obtain　the　optimum　parameters.　Surface　texturing　of　Kovar　alloy　through　fiber　laser　was　performed　for　achieving　the　reliable　joining　quality.　The　microstructure　of　joint　interface　and　fracture　morphology　were　observed　by　Scanning　Electron　Microscope　(SEM),　the　distribution　of　elements　was　analyzed　by　Energy　Dispersive　System　(EDS),　and　the　compressive　shear　strength　of　joint　were　tested.　The　results　indicated　that　the　higher　laser　power,　the　more　Fe2SiO4　in　the　reaction　products　when　the　laser　scanning　rate　is　fixed.　The　maximum　compressive　shear　strength　of　joint　reached　5.8　MPa　when　the　laser　power　was　650　W　and　scanning　rate　was　15mm/s.　While　the　maximum　compressive　shear　strength　of　glass-textured　metal　joint　was　12.9　MPa　under　the　same　laser　process　parameters,　which　increased　by　122.4%　compared　with　the　glass-non-textured　metal　joint.　©　2016,　Editorial　Board　of　Transactions　of　the　China　Welding　Institution,　Magazine　Agency　Welding.　All　right　reserved.
