8. Influence of tool steel carbide orientation on sliding wear
University essay from Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Abstract : For SMF industry, galling of tool in SMF operation during forming of stainless steel is a major concern, this increase the interest to study influence of tool microstructure on galling. In the present work, ingot cast AISI D2 were evaluated concerning wear mechanisms and critical sliding distance against austenitic stainless steel sheet in lubricated sliding condition at different contact pressures using a slider-on-flat-surface (SOFS) tribometer for carbide phases oriented in three different directions.

9. Effects of tempering on corrosion properties of high nitrogen alloyed tooling steels in pyrolysis oil
University essay from KTH/KorrosionsläraAbstract : Nowdays biofuels are becoming a good alternative for petroleum fuels due to environmental issues like high carbon dioxide emission and increasing vehicles population, together with the high price and fast depletion of petroleum oils. This project aims to investigate the corrosive effects of wood Pyrolysis oil on a special grade of nitrogen alloyed tooling steels to be used for injector nozzles in Diesel engines, where high stress and strain encounter high acidity and corrosivity of the Pyrolysis oil and cause breakdown over short periods.

10. Nanotribological characterization of advanced tool steels
University essay from Karlstads universitet/Avdelningen för maskin- och materialteknikAbstract : Tribological problems of tool–work piece interaction is a key aspect influencing product quality, process performance and tool lifetime. For example, in sheet metal forming operations, sliding contact may cause adhesive wear of sheet materials with build up of worn material on the tool surface. READ MORE
