Abstract
This paper concerns the wear of the working area of the permanent mould is strictly related to downfall in its functional properties. It may be caused by several different physical and chemical processes occurring during its exploitation and resulting mainly from the working conditions. The simplest wear factor is the material loss in the functional layer of the tooling, resulting mainly from the plastic strain, friction, corrosion or cracks of the surface layer. The tests were focused on comparative tests of inserts for high-pressure die-casting molds after their regeneration. Two methods were used for this process: TIG welding and laser surfacing. The scope of research included the study of surface microtopography and material structure on metallographic specimens. In particular, the thickness of the overlay layer, the heat affected zone were examined.
