This study presents the research results of the durability of coating (thermal and anti-erosion barrier) of a mincer cap casting pressure mould. Tests were conducted with the use of an IDRA OL320 pressure machine. Durability of the mould with TiN coating applied by PVD was analyzed. The geometrical structure of the mould surface was assessed. It was found that the surface roughness and precipitations of metallurgical origin in the mould material, as well as the surface roughness of the coating do not influence the barrier lifespan as much as microcracks on the mould surface do.
