Abstract
A method of sintering cemented carbide bodies includes heating said bodies to the sintering temperature in a suitable atmosphere and cooling. If said cooling at least to below 1250° C. is performed in a higher speed i.e. at more than 20° C./min cemented carbide bodies with no surface layer of binder phase are obtained. This is an advantage when said bodies are to be coated with wear resistant layers by the use of CVD-, MTCVD- or PVD-technique.
