The　wettability　of　glass　on　metal　can　be　enhanced　by　increasing　the　area　of　real　intimate　contact.　The　paper　presented　electron　beam　texturing　on　Kovar　alloy　to　improve　the　surface　micro-roughness.　The　wetting　behavior　of　borosilicate　glass　on　textured　Kovar　alloy　was　investigated　by　sessile　drop　method.　The　results　indicated　that　the　increase　of　effective　contact　area　by　using　electron　beam　texturing　facilitated　the　spreading　of　molten　glass.　The　contact　angle　decreases　continuously　with　the　increase　of　heating　temperature　and　holding　time.　The　main　reaction　products　between　glass　and　oxide　layer　are　Fe2SiO4.　The　high-energy　beam　texturing　and　pre-oxidation　on　the　metal　surface　promoted　the　mechanical-chemical　bonding　of　glass　and　metal　effectively,　which　improves　the　connection　strength　of　glass　and　metal.　©　2016,　Editorial　Board　of　Transactions　of　the　China　Welding　Institution,　Magazine　Agency　Welding.　All　right　reserved.
