Abraded Surface Properties of Sintered Carbide Specimens Before and After Deposition of a Thin Layer Using PVD

Popis výsledku v původním jazyce

Two series of samples were produced from sintered carbide WC-Co by using a pulsed laser. Due to the different parameters used for the ablation process, the ablation textures which were created have significantly different properties. From each series of samples, some were selected for deposition of a thin layer by PVD (physical vapour deposition). Metallographic analysis was used to evaluate the properties of the laser treated surface, supplemented by analysis of the chemical composition, hardness, fracture toughness of KIC, tribological properties, and adhesion properties of the prepared samples. The results from the analyses of the ablated surface samples were then compared with the results obtained from the ground surface samples. By comparing the results, it was found that with the correct parameters set for laser ablation, it is possible to obtain a surface with better abrasion properties for the deposition of the PVD layer on the substrate than with the ground surface.
