Abstract
Described is a wear-resistant roller component for handling abrasive materials where the component comprises a metal body with at least one surface. It is characterized in that a metal template having a pattern of through-going holes is arranged on the at least one surface of the metal body and in that a cover arranged to cover at least a part of the metal template is located at a distance from the metal template to form a gap between the cover and the metal template and in that a powder material suitable for sintering is introduced into the through-going holes in the metal template through the gap and in that the metal body, the metal template, the cover and the material powder are bonded together by means of a sintering process.
