- Angular momentum pumps are very often applied on-board ships. These pumps are used in cooling circuits of medium and high power engines, power plant boilers as well as bilge, ballast and fire installations. Such an extensive use of angular momentum pumps on board is connected with their numerous advantages. However, during operation the wear of marine hull, the rotor and shaft seals take place. The research attempts to increase the service life of shafts. The article presents the research results referring to the analysis of the influence of finish treatment (finishing turning, grinding, burnishing) on the friction properties of steel applied to marine pump shafts. The research was performed on a roller 39 mm in diameter made of 304L stainless steel. The finish tooling of pump shaft pins was carry out on a universal centre lathe. The finish turning process was carried out by means of a WING WF 080408 Sandvik Coromant cutting tool with replaceable inserts. The grinding process was performed by grinding attachment for lathes. The 1 – 80x10x32 – 99C 80-N V grinding wheel was used for the process. The process of burnishing was done by SRMD single roll burnishing tool by Yamato. The burnishing process was carried out at the following technological parameters: burnishing force 1.1 kN, burnishing speed 35 m/min, feed 0.13 mm/rev. In addition, the influence of the number of burnishing tool passes on the friction was determined. The paper will present the research results of test on the friction properties examination of samples after finish machining. The experiment was performed on T-05 block-on-ring wear tester.
