Abstract: A holder and an insert for a metering device for coating liquid or viscous coating medium onto a moving material web. The holder being elongated and including an insert groove, a locking rod groove and a locking rod being movably received in the locking rod groove and being formed with locking portions adapted to project through a slot and with releasing portions. The insert being elongated and including a coating rod groove being adapted to rotatably support a coating rod, and one or more engagement formations being adapted to interact with the locking rod to allow the insert to be inserted into and released from the insert groove when the locking rod is in a releasing position, and to allow secure holding of the insert in the insert groove when the locking rod is in a locking position, in which the engagement formations is in engagement with the locking rod.

Abstract: Disc- or plate-shaped targets for sputtering systems are attached to associated cooling plates by plasma-spraying a surface of such target with a compatible adhesive layer, for example composed of Ni; Ni/Cr mixtures; 80/20 Ni/Al mixtures; Ni/Al/Mo mixtures; Al/bronze mixtures; Mo; W; Al/Si mixtures, Zn, Cu, Cu/glass mixtures, etc., and then coating such adhesive layer with a solderable layer, for example composed of Cu, Cu/glass mixture or Ag, etc., and soldering such solderable layer onto the surface of a cooling plate. Preferably, the adhesive layer and the solderable layer are applied via plasma spraying.
