MECHANICAL PROPERTIES OF TOOL STEELS WITH DIFFUSION CARBIDE AND NITRO-CARBON LAYERS
The paper presents results of metallographic investigations and wear tests of the following tool steel grades: hot strain steels 4H5W2FS, 4H5MWS and cold strain steels H12, H12FS. All the surfaces have been hardened with the help of carbidizing and nitro-carbonizing processes in the powder medium. T...

| Zusammenfassung: | The paper presents results of metallographic investigations and wear tests of the following tool steel grades: hot strain steels 4H5W2FS, 4H5MWS and cold strain steels H12, H12FS. All the surfaces have been hardened with the help of carbidizing and nitro-carbonizing processes in the powder medium. The following factors have been investigated: morphology, thickness and microhardness of the obtained samples, their microstructure and phase composition. It has been determined that the application of the proposed technology makes it possible to improve wear resistance of the investigated tool steels at sliding friction. |
