porous sleeves
iron sinter
laser-made micro-segments - Opis:
- In this article some results of the research on the new generation slide porous bearings sintered from Höganas NC.100.24 iron powder, with 2.5% addition by weight of copper, with micro-segments (paths) made on their sliding surface with CO2 laser, with increased hardness and locally reduced surface porosity, are presented. The research was carried out within the framework of PBR/15-249/2007/WAT-OR00002904 Research Project financed by the Ministry of Science and Higher Education, during 2007 – 2011 [1]. Significant increase of the load capacity of the porous sleeves with paths, in comparison with the same Ø25/Ø35 x 20 mm sleeves without paths, was obtained. Durability of the bearings was also slightly higher; however, in comparison with the sleeves with macro-segments made of solid material, durability of the new generation bearings was several times higher. The sleeves sintered from iron powder with micro-segments made on their surface with the laser technique have not been previously known. Promising results in terms of increase of load capacity and durability caused that authors decided to submit a proper patent claim to the Polish Patent Office [2].
