Abstract

The present application describes a method of applying a firmly adhering cerium misch metal coating to the surface of a splinter-active component of an incendiary splinter projectile, namely to the outer lining and/or the inner lining of a steel projectile casing possibly pre-fragmented through structural weakening or to the surface of construction splinters of steel, hard metal or heavy metal, by using a splinter-active component containing as adhesion promoter for its basis metal and for the cerium misch metal at least one metal in the form of a matrix for the basic metal or as alloying component of the basic metal or in the form of an intermediate layer on the splinter-active component, the affinity of this metal to cerium misch metal being higher than the affinity of the basic metal of the splinter-active component, and by employing a low-pressure wire spraying method for the coating of the splinter-active component with molten cerium misch metal, said coated component being tempered in the usual manner after the solidification of the coating in order to additionally improve adhesion.
