Abstract

The invention relates to an apparatus ( 2 ) for generating electrical discharge in a fluid medium ( 3 ) in order to generate electrohydraulic shock waves. The electrodes ( 1 ) consist of a metallic work material. An electrical voltage is applied to the electrodes ( 1 ) in order to generate a voltage breakdown between the tips of the electrodes in the fluid medium ( 3 ), which work material consists of a tantalum alloy having a tantalum component greater than 60% or a tungsten alloy having a tungsten component greater than 60%.

Claims (19)

1 . Apparatus ( 2 ) for generating electrical discharge in a fluid medium ( 3 ) for generating electrohydraulic shock waves, with electrodes ( 1 ) consisting of a metallic work material in which fluid medium ( 3 ) an electrical voltage can be applied to the electrodes ( 1 ) for the purpose of generating a voltage breakdown between the tips of the electrodes ( 1 ), characterized in that the metallic work material consists of a tantalum alloy having a tantalum component greater than 60%.

2 . Apparatus according to claim 1 , in which the tantalum alloy has an tungsten component greater than 1%.

3 . Apparatus according to claim 1 , in which the tantalum alloy has an niobium component greater than 1%.
