    摘要: There is disclosed a method of coating cemented carbide inserts at least partly with a layer of at least one iron group metal. When inserts coated with such a layer are brazed to a tool holder, a joint with improved strength is obtained. According to the present method, one or more metal salts of at least one iron group metal containing organic groups are dissolved and complex bound in at least one polar solvent with at least one complex former comprising functional groups in the form of OH or NR.sub.3 (R.dbd.H or alkyl). A soluble carbon source is added to the solution which is subsequently at least partly applied to the cemented carbide inserts by dipping, spraying or painting. The inserts are dried and heat treated in an inert and/or reducing atmosphere. As a result, cemented carbide inserts are obtained at least partly coated with a layer of an iron group metal.
