摘要： PROBLEM TO BE SOLVED: To provide a method of manufacturing a carburized sintered body for manufacturing the carburized sintered body of high strength efficiently.SOLUTION: The method of manufacturing the carburized sintered body includes: a molding step of molding raw material powder by pressure to obtain a molded body, the raw material powder obtained by adding Fe-Mn-Si-C powder that consists of an alloy or compound of Fe, Mn, and Si and C to iron alloy powder; and a carburizing step of heating the molded body in a carburizing atmosphere with a carburization temperature of 850-980°C to obtain the carburized sintered body that is a sintered body with a carburized layer formed near a surface thereof. The Fe-Mn-Si-C powder reduces and activates the particle surface of the iron alloy powder, and thereby a so-called sintering neck is formed between the particles of the iron alloy powder during the carburizing step. Therefore, both sintering of the molded body and the formation of the carburized layer are performed in the carburizing step without a sintering step. Thus, according to this manufacturing method, the carburized sintered body of high strength can be efficiently manufactured at low cost.
摘要翻译：要解决的问题：提供一种制造渗碳烧结体的方法，用于有效地制造高强度的渗碳烧结体。解决方案：渗碳烧结体的制造方法包括：通过压力成型原料粉末以获得成型体的成型步骤，通过添加Fe-Mn-Si-C粉末而获得的原料粉末 Fe，Mn，Si和C与Fe合金粉末的合金或化合物; 以及在渗碳温度为850-980℃的渗碳气氛中加热成型体的渗碳工序，得到在其表面附近形成有渗碳层的烧结体的渗碳烧结体。 Fe-Mn-Si-C粉末减少并激活铁合金粉末的颗粒表面，从而在渗碳步骤期间在铁合金粉末的颗粒之间形成所谓的烧结颈部。因此，在不进行烧结工序的渗碳工序中进行成型体的烧结和渗碳层的形成。因此，根据该制造方法，可以以低成本有效地制造高强度的渗碳烧结体。版权所有（C）2013，JPO＆INPIT
