AB  - The lubricated and dry sliding wear behaviour of ZA-27 alloy composites reinforced with Al2O3 particles of size 250 mu m was evaluated. The content of Al2O3 particles in the alloy was 3, 5 and 10 wt.%. Composites were produced by the compocasting process using mechanical mixing of the matrix, i.e. Al2O3 particles as reinforcement were added into the semi-solid ZA-27 alloy by infiltration and admixing. A block-on-disc wear test device was used to evaluate the wear rate, whereat 30CrNiMo8 steel disc was used as the counterface, under dry and lubricated sliding conditions at different specific loads and sliding speeds. Results indicated that the wear rates of the composites were lower than those of the matrix alloy and further decreased with the increase in Al2O3 particles content in all combinations of applied loads and sliding speeds both in dry and lubricated tests.

AB  - Tribological behaviour of four different heat-treated Ti6Al4V alloys, during linear reciprocating sliding against alumina, on the microscale was investigated. Experiments were carried out for dry sliding and in the Ringer solution, over a range of loads (100-1000 mN) and speeds (4-12 mm/s). The wear mechanisms were investigated based on observations of worn surfaces. Specific wear rates for tested Ti6Al4V alloy were of order of 10(-7)-10(-4) mm(3)/N m. The lowest wear factor (order of 10(-7) mm(3)/N m) was observed for the Ti6Al4V annealed for I h at 750 degrees C in Ar atmosphere and then cooled down to room temperature in the furnace, tested in the Ringer solution. Load dependence of the wear factor exhibited transition characteristics. Wear mechanism has changed with change of load. The Ringer solution lowered wear factor for all tested conditions.
