| Abstract | This study deals with the different types of wear as well as other parameters present in the tribological system pistonsegment- cylinder in a combustion engine. By means of engineering methods were defined the wear rates in the three components of the system. The biggest wear in the analysis resulted in the cylinder shirt. Specialized methods applied were used to analyze the prevailing metallographic characteristics in its original construction, obtaining a gray melted iron with perlitic matrix. A new material with bainitic matrix has been proposed for increasing wear resistance. To demonstrate the efficiency of this new product, the experimental techniques carried out, were based on a dynamometric testing in a internal combustion engine diesel cycle Scania of 150 kW. It was exposed to a full charge during 500 h with 30 % of potency rising. Compared with the perlitic one, it has been proved that the bainitic matrix allows a better result. Besides, a superior dimensional stability was obtained. The piston segments had a similar wear rate in both materials in reference to the original tribological pair of the project. |
