:2002-10-09:I.Cremer(1968-),,,,,。MIMI.Cremer(Dueren-Konzendorf,D-52355,Germany) :本文介绍了金属粉末注射成形(MIM)零件的先进热加工工艺及设备。由于MIM-Mas-ter系列设备具有连续脱粘-高温烧结及快速冷却功能,可在大规模生产时加强工艺参数的控制,改善产品质量。最后把高温烧结和快速冷却组成一个连续过程,能实现MIM零件烧成品的硬化。快速冷却的独特优点是在分解氨气氛中烧结316L不锈钢可提高其密度,并可以采用可靠而价廉的气氛以降低成本。:烧结设备;注射成形连续烧结;脱粘结剂;不锈钢:TF124 :A:1006-6543(2003)01-0030-04ADVANCEDTHERMALPROCESSINGANDEQUIPMENTOFMIM-PARTSIngoCremer(CremerThermoprozessanlagenGmbH,Dueren-Konzendorf,D-52355,Germany)Abstract:ThispaperdescribesthelatestincontinuousthermalprocessingandequipmentofMIM-parts.OwingtotheMIM-Masterseriesequippedwithcontinuousdebinding,hightemperaturesinteringandrapidcooling,itenhancesthecontrolofprocessparametersandimprovesthequalityatlargescateproduction.Finallythenewdevelopmentsofhigh-temperaturesinteringandrapid-coolingintegratedinonecontinuousprocesscouldrealizesinter-hardeningofMIM-parts.Aspecialbenefitoftherapid-coolingisthepossibili-tytoenhancethedensityof316Lstainlesssteelwhensinteringundercrackedammonia,offeringthepossi-bilitytousethisreliableandcosteffectiveatmosphere.Keywords:sinterequipment;MIM;continuoussintering;debinding;stainlesssteel MIM()、。2080,,。,MIM,MIM。,MIM(1000000)(≈200g)。,MIM。,。,。。,,。(“”),。2090,MIM-[1]。“MIM-Master”MIM。13 120032 POWDERMETALLURGYINDUSTRY Vol.13No.1Feb.2003DOI:10.13228/j.boyuan.issn1006-6543.2003.01.012。。1 1.1 1MIM-Master6。。,。1 MIM-Master1-;2-(N2H2),1450℃;3-;4-;5-;6-();7-;8-;9-;10-;11- [2]。MIM,,:(1)Al2O3,1450℃。(2),(14)。(3)。(4)。MIM,,316L(1360~1370℃)。,。(),±3℃(4)。,。(30~40min)。。,5%。MIM1250℃1370℃,CH4,。,1 %N2%H2%Fe-0.8C-2Ni0.795~973~5Fe-0.21C-0.6Ni-0.5Cr-0.2Mo(AISI8620)0.2 100 0 Fe-0.03C-17Cr-13Ni-2Mo(AISI316L)0.01 0257575Fe-0.2C-13Cr(AISI420)0.3 97 Fe-0.07C-17Cr-4Ni-0.3Nb-3.5Cu(17-4-PH)0.03 0 100 ·31·1 I.Cremer:MIM ,N2H2。1。 ,。,(99.9%),。(,)。。1.2 1。,。,1。。,,。,“”。2,。BASF,。,。,。。,。。,2。2 (200L)·h-1300640()m3·h-168mL·h-1180400(,)4%1% :6h(~)2 2.1 ,。,。。。1,。。,。,。,。,。。,,。2.2 。,。,。,。。1~4℃s,[2]。,。-。。316L。316LN2[3,4]。9001100℃,。,,。。·32· 13,,(1360℃)。(,)。3316L。MIM-Master。,。3 H2N2()%g·cm-3100007.921000207.929010207.529010507.70752507.427525207.507525507.637525807.84 ,。,7.5gcm3。,10%~20%。3 。,。-。。[1] CremerI.[C].ProceedingsofthePowderMetallurgyWorldCongress1994,Paris,6-9June1994,2:1165-1168.[2] CremerI.[C].ProceedingsofthePowderMetallurgyWorldCongress.Kyoto12-17Nov.,2000.[3] LallC.[C].Int.J.ofPowderMetallurgy,1991,27(4):315-329.[4] SvilarM,AmbsHD.[C].AdvancesinPowderMetallurgy,1992,2:259-272.
