  6. 5. Effects of tempering on corrosion properties of high nitrogen alloyed tooling steels in pyrolysis oil

    University essay from KTH/Korrosionslära

    Author : Ashkan Reza Gholi; [2011]
    Keywords : High nitrogen alloyed tooling steel; Pyrolysis; Tempering process; Primary and secondary chromium precipitates; Pitting corrosion; General corrosion;

    Abstract : 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.
