Opis:: Angular momentum pumps are very often applied onboard ships. These pumps are used in cooling circuits of medium and high power engines, power plant boilers and in bilge, ballast and fire installations. Very extensive use of angular momentum pumps on board is connected with their numerous advantages. 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 (lathing, grinding and burnishing) on the corrosion properties of steel applied to marine pump shafts. The research was performed on a roller of 40 mm in diameter made of X5CrNi18-10 (AISI 304 L) stainless steel. The lathing process was carried out by means of a WNMG 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 burnisher by Yamato. In addition, the influence of the burnisher passes number on the corrosion properties was determined. The paper will present the results of electrochemical impedance spectroscopy research. To conduct the survey the Atlas 0531 EU and IA potentiostat was used. Determination of the corrosion process parameters was performed computer programs: AtlasLab 2.0 and EIS Spectrum Analyzer.

Opis:: The article presents the results of the mechanical properties of aluminium alloy AW 5059 [AlMg5.5Zn] welded by MIG and friction stir welding FSW. Friction Stir Welding (FSW) – a new technology can be successfully used for butt welding of different types of aluminium alloy sheets. Research results on stress corrosion cracking for the AW 5059 alloy welded joints are presented. Stress corrosion cracking was examined via the slow-strain-rate-testing (SSRT) according to EN ISO 7539-7. The following parameters were measured: time-to-failure, obtained max. load, strain energy (the diagram surface under the stress-elongation curve), relative elongation of the specimen, tensile stress and reduction-in-area. The fractures were analysis by scanning electron microscope of Philips XL 30 type. Tests were carried out in the air and in a 3.5% water solution of NaCl – artificial sea water. On the basis of obtained test results, it can be said that 5059 alloy joints welded by FSW are resistant to stress corrosion in sea water. Tests have shown that the 5059 alloy, welded by FSW, has superior strength properties compared to the FSW 5083 alloy, along with comparable, good resistance to stress corrosion. Original value are received results of the mechanical and corrosion properties of a new method friction stir welding used for joining AW 5059 alloy sheets.

Opis:: The results of stress corrosion cracking (SCC) of aluminum alloy AW 7020 [AlZn5Mg1] welded by friction stir welding FSW and MIG were presented. Friction Stir Welding (FSW) - a new technology can be successfully used for butt welding of different types of aluminum alloy sheets. In the article the parameters for friction stir welding ofsheets made of AlZn5Mg1 [7020] alloy was presented as well as parameters for MIG. Metallographic analysis of bonds showed a proper structural construction of both, the FSW and MIG welded 7020 aluminum alloys. Stress corrosion cracking was examined via the slow-strain-rate-testing (SSRT) according to EN ISO 7539-7. The following parameters were measured: time-to-failure - T [h], obtained max. load - F [N]; strain energy (the diagram surface under the stress-elongation curve) - E [MJ/m3]; relative elongation of the specimen — a10 [%]; max. tensile stress — R [MPa] and contraction — Z [%]. The tests were carried out on cylindrical notch-free specimens in the air and 3.5% water solution NaCl. Good resistance to stress corrosion was found of friction stir welded 7020 aluminum alloys. The tested samples cracked during SSRT test in the native material in case of FSW and in the joint in case of MIG. Original value are received results of the stress corrosion resistance of new method friction stir welded AlZn5Mg1 alloy compared with traditional MIG method.

W artykule przedstawiono wyniki badań własności mechanicznych oraz podatności na korozję naprężeniową złączy zgrzewanych tarciowo (FSW) stopu AW 7020 [AlZn5Mg1]. Nową technologię zgrzewania tarciowego z przemieszaniem materiału zgrzeiny FSW (Friction Stir Welding) można z powodzeniem stosować do zgrzewania doczołowego blach z różnego rodzaju stopów aluminium. Przedstawiono parametry zgrzewania tarciowego (FSW) zastosowane do połączenia blach ze stopuAlZn5Mg [7020]. Analiza metalograficzna wykazała poprawną budowę strukturalną złączy zgrzewanych stopu aluminium 7020. Badania korozji naprężeniowej wykonano stosując próbę odkształcenia z małą prędkością (10-6 s-1), zgodnie z PN-EN ISO 7539-7. Parametrami mierzonymi podczas badań były: czas do zniszczenia - T [h], uzyskane maksymalne obciążenie - F [N], energia odkształcenia (powierzchnia wykresu pod krzywą naprężenie-wydłużenie) - E [MJ/m3], wydłużenie względne próbki - A10 [%], maksymalne naprężenia rozciągające - R [MPa] oraz przewężenie - Z [%]. Badania wykonano na próbkach gładkich cylindrycznych w powietrzu oraz sztucznej wodzie morskiej. Na podstawie otrzymanych wyników badań stwierdzono dobrą odporność na korozję naprężeniową złącza stopu aluminium 7020 zgrzewanego metodą FSW. Oryginalnym osiągnięciem są otrzymane wyniki odporności na korozję naprężeniową złączy stopu AlZn5Mg1 zgrzewanych tarciowo nową metodą Friction Stir Welding.
