METHOD FOR PRODUCTION OF SYNTERIZED COMPONENTS |
abstract |
The invention relates to a method for producing a sintered component (2) comprising the steps of: providing a chromium iron-based powder; introduce the powder into a dusting press and forming a green piece; sintering the green part forming the sintered component (2); further compact the sintered component (2); quenching of the sintered component (2). sintering is performed in a decarburizing atmosphere and the sintering element (2) for surface compaction along an axis (3) is moved from a first die opening (6) towards a second die opening (13) ) opposite the first die opening (6) along the axis (3) of a die tool (1), wherein the sintered component (2) during this movement passes through several die segments (7-11) of the tool and thus a surface zone of the sintered component (2) is compacted, wherein in the pressing direction an inner diameter (17) of the successive matrix segments (7-11) becomes smaller and the individual matrix segments 7-11 are arranged such that a subsequent matrix segment 7-11 of the various matrix segments 7-11 becomes immediately adjacent to the corresponding matrix segment 7-11, antecedent in the pressing direction. |
