  • Bejger, Artur; Drzewieniecki, Jan (Scientific Journals of the Maritime University of Szczecin, Zeszyty Naukowe Akademii Morskiej w Szczecinie, 2015)
    This article draws attention to the problems of maintaining fuel injection pumps of marine diesel engines in the conditions of use of residual fuels whose quality is steadily deteriorating, and also burned under engine’s reduced load and in situations where the international rules require a temporary change over into distillate fuels. The analysis of tribological processes occurring in hydraulic precision pairs of fuel injection pump such as barrel-plunger was presented and the types of occurring wears were discussed based on author’s own operational experience. There was pointed out the need for additional methods of verification / evaluation of technical condition using of technical diagnostic methods.
  • Chmiel, Jarosław; Górnicki, Kazimierz (Scientific Journals Maritime University of Szczecin, Zeszyty Naukowe Akademia Morska w Szczecinie, )
    The authors deal with the most important problems of the wear of metal elements in port grain silos. The properties of grains and their cereal products cause an intensive abrasive wear process in in-port transport equipment. Corrosion phenomena that occur during stoppage periods additionally accelerate the destruction of steel elements.
  • Chmiel, Jarosław; Górnicki, Kazimierz (Scientific Journals Maritime University of Szczecin, Zeszyty Naukowe Akademia Morska w Szczecinie, )
    The concise list of basic groups of wear phenomena is presented. These exist in installations intended for the transportation of liquid cargo in the marine environment. The basic role of synergic phenomena in the processes of accelerated wear is discussed. The need of including the complex wear phenomena into teaching programs is indicated

    The results of research on selected mechanical properties of composite material on the matrix of intermetallic phase Fe-Al reinforced with Al2O3 particles are presented. The influence of particle quantity and size on tribologic properties of selected composite material was examinedas well as the influence of resistance on erosion wear of the ma-terial was investigated. Significant improvement of properties was recorded in the com-posite material reinforced with Al2O3 particles with nickel layer placed on their surface.
