Abstract

Plastic mouldings which contain sintered material powder and solder powder are used for applying layers of sintered material to metal substrates. Non-corrosive decomposition products on heating and good burn-out of the plastic are obtained with mouldings which, in addition to 5 to 40% by volume of plastic, contain 5 to 40% by volume of pores, the remainder being sintered materials or solder, the plastic having to consist of ethylene/vinyl acetate, ethylene/propylene rubber and/or butyl rubber.
