Life extension of gears flank surfaces regenerated by hard facing
(Editura Stiintifica Fmr, Bucharest, 2013)
This paper contains the results of experimental analysis of fatigue endurance of used steel teeth regenerated by hard facing. The cylindrical spur gears were tested and compared with the newly made ones, oiler being ...
Process parameters influence on microstructural properties of hypereutectic al-18wt% Si alloys obtained by rheocasting process
(Editura Stiintifica Fmr, Bucharest, 2012)
Hypereutectic Al-18wt%Si alloy was obtained by conventional and rheocasting procedure at cooling rate 0.16 +/- 0.05 degrees Cs-1. Samples of rheocasted alloy were obtained at two stirring speeds 1000 and 1500 rpm. Tests ...
Synthesis, characterization and application of the filler based on corundum for obtaining the ceramic coats in foundry
(Editura Stiintifica Fmr, Bucharest, 2012)
In this work, a possibility to develop new ceramic coats based corundum for casting applications has been examined. Optimization of coating composition with controlled rheological properties was attained by applying different ...
The possibility of substitution of wear resistant low chromium white iron resistant with basalt melt
(Editura Stiintifica Fmr, Bucharest, 2012)
In this study the testing results of the possibility of substituting mill lining plates for ore milling made of low chromium white iron that is resistant to wear with plates made of basalt melt are presented. Plates made ...
