I-Sintering ye-powder metallurgy factory operations ayilonyathelo lokugqibela-lixesha lokwenza okanye lokuqhawula inxalenye yengqibelelo, ukuzinza komda, kunye nokusebenza kwexesha elide kwizicelo ezinoxinzelelo oluphezulu. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Siye safaka ngaphezulu kwe-12,000 yeebhetshi ze-cobalt-nickel alloy compacts ukususela ngo-2018-ingakumbi i-AMS 5387 kunye ne-T800-grade izinto ezilungiselelwe izindlu zempompo ze-hydraulic, izihlalo zevalve yoxinzelelo, izihlalo zevalve ye-rolling kunye ne-winers. Into esiyifundileyo yayingekho kwiincwadi zezifundo. Ivele kwizigodo zesithando somlilo, iskena se-microstructure, kunye nohlalutyo oluphindaphindiweyo lwengcambu xa ubuninzi behla nge-0.3% kwi-1,185 ° C okanye ukukhula kweenkozo ku-spiked ngexesha lokupholisa i-nitrogen-diluted.
Ulawulo lweProfayile yoBubushushu ayixoxisi—Ingakumbi kwiiSuperalloys
Uninzi lweentsilelo ekufakweni kwemigca yemveliso yesinyithi yomgubo ibuyela emva kwi-thermal lag-hayi imida yezixhobo. Ukuphambuka kwe-15 ° C kwi-peak hold time shifts AMS 5387's intergranular phase distribution enough to cut fatigue life by 37% in piston pump cylinder housings. Sisebenzisa ii-double-zone molybdenum-heated furnaces ezine-real-time thermocouple feedback at three radial positions per load. Ukuqonda okubalulekileyo: amazinga e-ramp angaphantsi kwe-3 ° C / min ngaphantsi kwe-600 ° C akhusela ukuvuthwa kwe-binder ukubola; ngaphezu kwe-900 ° C, sibamba imizuzu ye-45-kungekhona i-60-ukuphepha ukusabalalisa kwe-cobalt ngokugqithiseleyo ngelixa ugcina i-≥98.2% yoxinaniso lwethiyori. Oku akuyothiyori. Yiprofayile egqithise ukuqinisekiswa kwe-ASTM B243 kumaqashiso angama-92 alandelelanayo.
Ubunyulu be-Atmosphere bulawula ngokuthe ngqo uBume beMfezeko-kunye nokuMachina
Umxholo weHydrojeni ubaluleke ngaphezu kokuhamba kwerhasi iyonke. Sibeka iliso kwindawo ye-H₂ rhoqo-hayi nje ukugxila kwi-inlet. Omnye umthengi we-cobalt alloy nozzles wabonisa i-micro-pitting emva konyango lobushushu. Uphando luveze i-inlet hydrogen kwi-99.99% yococeko-kodwa indawo yombethe kwi--42 ° C yazisa umphunga wamanzi ococekileyo owenziwe nge-oxidized imida yengqolowa ene-nickel ngexesha lokucoca. Isisombululo: yongeza i-cryogenic trapping kunye nokuqina kombethe ku--65 °C. Isiphumo: uburhabaxa bomphezulu (Ra) behle ukusuka kwi-1.8 µm ukuya kwi-0.6 µm pre-machining, ukusika ixesha lomjikelo we-CNC ngama-22%. Ukuphoswa kwentsimbi kunye namalungu ensimbi engenasici, sitshintshela kwi-ammonia edibeneyo <5 ppm O₂-iqinisekisiwe ngeyure nge-zirconia sensor. Akukho ngaphandle.
Ijiyometri yomthwalo kunye nokuxinana kohlaza kufuneka kufaniswe-kunganyuswa
Uxinaniso oluphezulu oluluhlaza luvakala ngcono—de lufike ukonakala. Sibeka ingxinano eluhlaza kwi-62-65% kwiindawo ezisekelwe kwi-T800 ubude kune-120 mm. Ngoba? Ngenxa yokuba ukucutha okungalinganiyo kwiicontours ezintsonkothileyo-ezifana nezo ze-winch shafts zemoto yobunjineli-kubangela i-0.18 mm bow ngobude obuyi-300 mm ukuba ukuxinana okuluhlaza kungaphezulu kwe-66%. Ukulungiswa kwethu: iitreyi zokulayisha ezicandiweyo ezinezikhonkwane zenkxaso ezihleliweyo. Amacandelo amancinci ahlala kwizitendi ze-ceramic ezichasayo; iziseko ezishinyeneyo ziphumla kwi-high-conductivity ye-silicon carbide pads. Ukwahluka kokuncipha kwehle ukusuka ku-±0.32% ukuya ku-±0.07%. Ibhonasi: Ukukhutshwa kwesithando somlilo kunyuke nge-18% kuba siphelise ukulungiswa kwe-post-sinter.
Uhlolo lweXesha lokwenyani lubetha uHlolo lwasemva kwenkqubo ngalo lonke ixesha
Siyekile ukuthembela kwisampula-based density checks emva kokuba i-batch ye-valve ye-pressure body ayiphumelelanga kuvavanyo lwe-hydrostatic kwi-410 bar-nangona kudlula ukuhlolwa kwe-CMM. Unobangela: i-porosity yendawo kufuphi neradiyi yangaphakathi ephoswe yi-single-point Archimedes measurement. Ngoku yonke i-sintering run feed data kwi-proprietary SinterTrack system yethu: i-thermocouple arrays log 120 points per load; abenzi boluvo bokulahleka kobunzima babona ukugqitywa kokudinwa kwe-binder ngaphakathi kwe-± 0.8 imizuzwana; Iikhamera ze-infrared imaphu yokutshintsha komphezulu wokukhutshwa kwezinto ezibonisa ukuhlangana kweenkozo kwangoko. Izilumkiso zibangela ukubamba-nophononongo oluzenzekelayo ukuba nayiphi na iparameter itenxa ngaphaya kwemida yolawulo eqinisekisiweyo ngokwezibalo-ibalwe ngokwebakala lemathiriyeli, hayi ngeziko ngalinye. Oku kunciphise amaqashiso angahambelaniyo ukusuka kwi-1.4% ukuya kwi-0.23% kwiinyanga ezili-18.
Ukuphucula akukho malunga neParameter enye-Kumalunga neZigqibo zokuNxibelelana
Impumelelo yomzi-mveliso wesinyithi wesinyithi umgubo ixhomekeke kwindlela umoya, ubushushu, ixesha, kunye nenxalenye yejometri ezidibana ngayo-hayi indlela nganye esebenza ngayo yodwa. Ubushushu obuphezulu obuyi-5°C buphucula ukuxinana kodwa buyenza ibe mandundu i-oxidation yomphezulu ngaphandle kokuba ubunyulu be-hydrogen buqina ngaxeshanye. Ukupholisa ngokukhawuleza kuphucula ubulukhuni kodwa kumema ii-microcracks ngaphandle kokuba ubuninzi obuluhlaza buhla kancinci. Kwi-QINGDAO QIANGSENYUAN, siphatha i-sintering njengenkqubo ye-loop evaliweyo: idatha ye-powder engenayo (ubungakanani be-particle D50, umxholo we-oksijini, izinga lokuhamba) lilungisa ngokuthe ngqo iindawo zokubeka isithando somlilo ngaphambi kokulayisha. Sabelana ngale ngqiqo-kungekhona iziphumo-kunye nabathengi ngexesha lophononongo lwe-GD&T. Kuba xa indlu yakho yempompo kufuneka iphile kwimijikelo engama-20,000 kwibhari engama-350, ukuthambisa akwenziwa. Kukuzaliseka isivumelwano sesinyithi.
