In a method for manufacturing a nozzle plate, two parts of the nozzle plate are fabricated separately from one another. The fabrication of the two parts is carried out by microstructuring/lithography, electroforming and plastic molding. Advantageously, a filter structure is provided in the first part. The two parts are joined together by means of laser welding, diffusion soldering or a chemical joining process. The nozzle plate is particularly well suited for injection valves, atomization nozzles, paint spray nozzles or other spraying systems.

To improve the adhesion of a nickel layer to a valve metal layer in a thin film electronic circuit, a boundary layer is created between the valve metal and the nickel layer. The boundary layer is created by oxidizing the valve metal surface and applying the nickel layer by cathode sputtering with sufficiently high energy to cause nickel-ion migration into the valve metal oxide layer. The so-formed boundary layer improves the mechanical adhesion of the nickel layer to the valve metal layer and also prevents penetration of solder to the valve metal layer since the boundary layer acts as a diffusion barrier.

A stable oxygen electrode which is in an active state and retains said activity for a long service life. The electrode comprises an electrode carrier and an activated transition metal chelate of 5,14-dihydrodibenzo(5,9,14,18)tetraaza(14)annulene. Said metal chelate is activated by heating in an inner gas atmosphere at a temperature of between about 600.degree. and 1000.degree.C for at least 5 minutes.
