COMPOSITION OF PARTICULATE MATERIALS FOR FORMING SELF- LUBRICATING PRODUCTS IN SINTERED STEEL, PRODUCT IN SELF- LUBRICATING SINTERED STEEL AND PROCESS FOR OBTAINING SELF-LUBRICATING PRODUCTS IN SINTERED STEEL |
摘要 |
The composition comprises the iron as the main particulate metallic material; at least one particulate alloy element, with the function of hardening the ferrous structural matrix; and a precursor non-metallic particulate compound, generally a carbide or a carbonate, which is capable of generating, upon its dissociation during the sintering, graphite nodules, whose formation is facilitated: by the precursor compound itself when it comprises a chemical element which stabilizes the iron alpha phase of the ferrous structural matrix; or by an additional alloy element included in the composition and which is defined by a chemical element that stabilizes the iron alpha phase during the sintering. The composition can be conformed by compaction or by powder injection molding. The process of the invention leads to obtaining products in self-lubricating sintered steel from said composition. |
