We have tried, unsuccessfully, to anodicaly bond alloy "39" to borosilicate (7740). Does anyone know what the basic process parameters are? Should we try different alloys? Any help on this would be greatly appreciated. Thanks, Mike Barton Creare, Inc. Etna Rd, PO Box 71 Hanover, NH 03755 Phn (603) 643-3800 fax (603) 643-4657 email MDB@Creare.com
