AB  - Cavitation erosion studies of steels produced by Electroslag Refining (ESR) and Argon Oxygen Decarburization (AOD refining) have been carried out. The experiments were conducted using the modified ultrasonically induced cavitation test method. Erosion rates were measured and the morphology of damages under cavitation action was studied by scanning electron microscopy and optical microscopy techniques. The present work is aimed at understanding the cavitation erosion behaviour of electroslag refined steel (ESR) compared with the steel produced by Argon Oxygen Decarburization (AOD refining), commonly used in the production of hydraulic machinery parts (Pelton blades). The results exhibited lower cavitation rate of ESR steel compared with AOD steel, as a consequence of its better mechanical properties and homogeneous and fine-grained microstructure.

AB  - Copper-based composites were obtained using high energy milling. The inert gas-atomized prealloyed copper powder (average particle size - 30 μm) containing 2 wt.% Al, and the mixture of electrolytic copper powder (average particle size – 30 and 15 μm) with 4 wt.% comertial Al2O3 powders (average particle size –0.75μm) served as starting materials. These powders were separately milled in air up to 20 h in the planetary ball mill. Milling of prealloyed copper powder promotes formation of nano-sized Al2O3 particles by internal oxidation with oxygen from air. It was calculated that by internal oxidation of 2 wt.% aluminum approximately 3.7 wt.% Al2O3 was generated in the copper matrix. Milled powders were treated in hydrogen at 400 °C for 1 h in order to eliminate copper oxides formed at the surface during milling. Compaction executed by hot-pressing was carried out in an argon atmosphere at 800 °C for 1 h under the pressure of 35 MPa. Compacts obtained from 5 and 20 h milled powders were additionally subjected to high-temperature exposure in argon at 800 °C for 1 and 5 h. The results were discussed in terms of the effects of different size of starting powder particles on structure, strengthening of copper matrix, thermal stability and electrical conductivity of the Cu - Al2O3 composite.

AB  - Inert gas atomized prealloyed copper powder containing 2 wt.% Al (average particle size approximate to 30 mu m) and a mixture consisting of copper (average particle sizes approximate to 15 mu m and 30 mu m) and 4 wt.% of commercial Al2O3 powder particles (average particle size approximate to 0.75 mu m) were milled separately in a high-energy planetary ball mill up to 20 h in air. Milling was performed in order to strengthen the copper matrix by grain size refinement and Al2O3 particles. Milling in air of prealloyed copper powder promoted formation of finely dispersed nano-sized Al2O3 particles by internal oxidation. On the other side, composite powders with commercial micro-sized Al2O3 particles were obtained by mechanical alloying. Following milling, powders were treated in hydrogen at 400 degrees C for 1h in order to eliminate copper oxides formed on their surface during milling. Hot pressing (800 degrees C for 3 h in argon at pressure of 35 MPa) was used for compaction of milled powders. Hot pressed composite compacts processed from 5 and 20 h milled powders were additionally subjected to high temperature exposure (800 degrees C for 1 and 5 h in argon) in order to examine their thermal stability. The results were discussed in terms of the effects of different size of starting powders, the grain size refinement and different size of Al2O3 particles on strengthening, thermal stability and electrical conductivity of copper-based composites.

AB  - The influence of diverse heat treatments on micro-structural and tribological characteristics of Ti-6Al-4V ELI (mass%) alloy, which is used as implant material in biomedical engineering, was investigated on a block-on-disc tribometer. Aim of the present study was to explore the possibility of Ti-6Al-4V ELI alloy wear resistance improvement, examining the effects of different heat treatments on alloy microstructure, as well as on alloy wear characteristics in simulated body conditions using light optical microscopy (LOM) and scanning electron microscopy (SEM). Results presented in this paper show that the influence of heat treatment on micro-structural and tribological characteristics of the investigated Ti-based alloy is significant and that it can be used for further wear resistance improvement of this widely used implant material. .
