Influence of laser remelting at cryogenic conditions on corrosion resistance of non-ferrous alloys The main reason for laser remelting of the components made of aluminium, copper and titanium alloys is to obtain high hardness and corrosion resistance at the surface for longer lifetime as result of the rapid solidification. The final microstructure, phase composition and properties of aluminium, copper and titanium alloys depend on the laser process parameters and obviously on the nature of the equilibrium system. The effect of laser surface remelting at cryogenic conditions on the microstructure and corrosion characteristics of the AlSi13Mg1CuNi, SUPERSTON and Ti-6Al-4V alloys are presented. The beneficial effects of laser treatment on the microstructure and corrosion behaviour of those alloys used for different products are observed.

B. Majkowska; Waldemar Serbiński; I. Skalski

Assessment of Cavitation Erosion Damage of Laser Remelted the Superston Alloy Influence of laser treatment at cryogenic conditions on surface microstructure after cavitation test of the SUPERSTON alloy are presented in this paper. The cavitation test was performed using the rotating disc facility in IPM PAN Gdansk. The kinetics of mass loss during the cavitation process was determined for casting and laser remelted specimens. Surface and cross-section microstructure of the SUPERSTON alloy after laser treatment and cavitation test was observed by optical and scanning electron microscope.

B. Majkowska; M. Jażdżewska; A. Zieliński; M. Antoszkiewicz

Dotychczasowe badania powierzchni wszczepow tytanowych dla chirurgii kostnej wykazaly, ze osteointegracja na powierzchniach rozwinietych jest znacznie szybsza niz na powierzchniach gladkich, co za tym idzie chropowatośc powierzchni implantu ma bardzo duzy wplyw na adhezje skladnikow środowiska biologicznego. W artykule przedstawiono wstepne wyniki badan dotyczące wplywu chropowatości powierzchni stopu Ti13Nb13Zr o bardzo malym module Younga na budowe wytworzonej powloki hydroksyapatytowej.

B. Majkowska; M. Jażdżewska; Damian Miotke; Emilia Wolowiec; A. Zieliński

The paper presents research results of resistance to abrasive wear of titanium alloys: Ti6Al4V (commonly used) and Til3Nb13Zr (alloy of new generation) in association with polyethylene (UHMW-PE) predisposed for elements on pair of the knee endoprosthesis. The results were analysed from the point of possibility of an use of new generation titanium alloys as components of such implants. The tests of resistance to abrasive wear of selected kinematic pairs were conducted with the PT-3 tribometer in Ringer’s solution a constant load 2.0 kN, rotational speed of the rotating specimens (Ti13Nb13Zr and Ti6Al4V) 30 rev/min, and test duration 1 or 2 hrs.

Effect of Crystallization Process at Cryogenic Conditions on the Functional Properties of the SUPERSTON Alloy Used in Production the Ship’s Propellers

B. Majkowska; Waldemar Serbiński

The purpose of this paper is to show results of laser treatment at cryogenic conditions of the SUPERSTON alloy used for ship’s propellers. That modification process ought to bring beneficial changes of microstructure and residual stresses in the surface layer. During the laser remelting at cryogenic conditions the microstructure changes significantly. This is related to synergistic effects of the solidification rate, phase transformations in the solid state and laser treatment parameters. That crystallization process had influence on functional properties such as corrosion and cavitation resistance of the SUPERSTON alloy which were tested during researches.

Cavitation Wearing of the SUPERSTON Alloy after Laser Treatment at Cryogenic Conditions

B. Majkowska; Waldemar Serbiński

The purpose of this paper is to demonstrate the method of laser remelting at cryogenic conditions of the SUPERSTON alloy and its influence on microstructure and cavitation wearing. The cavitation test was performed using the rotating disc facility in IPM PAN Gdansk. During the cavitation test, the mass loss of the material with different parameters of laser remelting was determined. Surface and cross-section microstructure of the SUPERSTON alloy after laser treatment and cavitation test were observed by scanning electron microscope. The cavitation resistance of the remelted SUPERSTON alloy was approximately 40% higher in comparison to the base material.
