Description

It is known that carbide size, height and orientation are very effective on wear properties such as galling and abrasive wear. Carbides can also act as stress points for crack initiation. Therefore, different carbide morphologies of Cr-Mo-V powder metallurgical tool steels with the similar composition were compared within the scope of this work.

In our study, larger carbides produced via new innovative process development of Uddeholms AB were subjected to abrasive wear test in order to verify the effect of carbide size on the pure abrasive wear resistance. Ductility of the material was measured by unnotched impact test. The microstructural evaluations were conducted by light-optical microscopy (LOM) and scanning electron microscopy (SEM) techniques. Abrasive wear property was studied with pin-on-disc test.
