Prediction of Thread Rolling Tools Wear Resistance

AbstractIn the paper, the issue of the cermet cutting tools wear resistance was addressed. The tool inserts made out of cermet composites were exposed to the ion implantation with ions of nitrogen N+ and with combination of nitrogen N+ and aluminum Al+ ions. In order to assess the impact of the ion implantation, the samples of stainless steel EZ6NCT25 were turned with the standard cutting tools and with the inserts after ion implantation. The results in general confirmed better wear resistance of the ion implanted inserts. In particular, they performed 20-40% smaller friction. After some time, when the destruction of the implanted surface layer took place, the friction coefficient rose up to the value typical for non-implanted inserts. For the implanted inserts, the wear index VB appeared to be lower, and even visual assessment revealed distinguishably smaller wear than in case of tools without ion implantation.

Resistance To Wear

Abstract VASCO WEAR is an air-hardening, cold-work die steel developed to provide high resistance to wear at exceptionally good levels of toughness. It also has the high compressive strength necessary for maximum resistance to upsetting. Its many uses include such applications as thread-rolling dies, punches and blanking dies. This datasheet provides information on composition, physical properties, elasticity, and compressive strength as well as fracture toughness. It also includes information on wear resistance as well as forming, heat treating, machining, and surface treatment. Filing Code: TS-320. Producer or source: Teledyne Vasco.

Further Development

Ceramics, such as Al2O3 and SiC have numerous current and potential uses in applications where high temperature strength, hardness, and wear resistance are required often in corrosive environments. These materials are, however, highly anisotropic and brittle, so that their mechanical behavior is often unpredictable. The further development of these materials will require a better understanding of the basic mechanisms controlling deformation, wear, and fracture.The purpose of this talk is to describe applications of TEM to the study of the deformation, wear, and fracture of Al2O3. Similar studies are currently being conducted on SiC and the techniques involved should be applicable to a wide range of hard, brittle materials.
