Analysis of abrasive wear resistance of the d2 tool steel in relation to heat treatment

Heat treatment significantly influences wear resistance of the tool steels. D2 is suitable for the cutting and forming cold work tools. Heat treatment of the parts must be in accordance with the function of the tool positions. When high austenitized, it is suitable for application of PVD coatings which further enhance its operating characteristics. This article refers to relationship between the hardened-and-tempered condition of this tool steel and its abrasive wear resistance. The samples were subjected to the different heat treatment parameters, then were tested using dry sand and rubber wheel method. Microstructural analysis of the representative samples is presented and related to the obtained results of the dry sand/rubber wheel test.
