ANALYSIS OF THE STRUCTURE AND TRIBOLOGICAL PROPERTIES OF SINTERED STAINLESS STEELS
Journal Title: Tribologia - Year 2017, Vol 272, Issue 2
Abstract
Increasing development of civilization encourages the search for modern engineering materials. At present, very interesting and promising materials are sintered stainless steels that are considered to be the most rapidly developing group of materials, which is related to the demand for materials with good mechanical properties and high resistance to corrosive agents. Taking into account sintered austenitic–ferritic steels, it is possible to obtain a structure with different proportions of the two basic structural components. The main problem limiting the applicability of sintered stainless steels is porosity, which deteriorates not only the strength properties but also the usability as compared to their cast and materials after plastic working. Extremely valuable factors influencing tribological properties are the chemical composition, proportion of individual powders and sintering conditions. In this study, the microstructure and tribological properties of sintered stainless steels obtained by sintering in different proportions of 316L austenitic steel and 409L ferritic steel were compared. The abrasion wear resistance test for individual sintered steels was performed by pin-on-disc method.<br/><br/>
