摘要：

Thin aluminium plate was welded onto a zirconia ceramic by the use of a newly developed explosive welding technique. A 0.1 mm-thick aluminium plate was accelerated about 800 m s(-1) by regulated underwater shock wave and collided with a zirconia plate at a certain collision angle under moderate conditions for explosive welding. The use of a stainless steel cover plate above an aluminium plate and the use of ceramic block next to the ceramic to be welded, were effective in eliminating cracks generated in the ceramic. The use of a ceramic container made from epoxy resin mixed with steel powders was also useful in crack reducton. No separation at the bonded interface was observed at the fracture surface obtained through a bending test in a sample fabricated under moderate conditions. (C) 1999 Elsevier Science S.A.
