Odolnost slinutého karbidu vůči vzniku a šíření tepelných trhlin / Resistance of Sintered Carbides against Thermal Crack Spreading

This thesis aims to compare the relationship of physical-mechanical properties of tool materials made of WC-Co sintered carbides with their resistance to initiation and propagation of thermal cracks. The paper presents the results of testing the basic physical-mechanical properties of the three samples sintered carbides with different percentage of Co binder. Next, this thesis describes the progress and results of quench experiment and cutting tests using, which was described resistance of the tested samples to thermal and mechanical shock, depending on the values of physical-mechanical properties.
