I-Metallurgy ye-Powder yinkqubo yeteknoloji eyenza isinyithi okanye isebenzise umgubo wesinyithi njengezinto eziluhlaza, emva kokuqulunqa kunye ne-sintering, ukuvelisa izinto zetsimbi, i-composites kunye neentlobo ezahlukeneyo zeemveliso.

Inkqubo yetekhnoloji ye-powder metallurgy
1. Ukulungiselela umgubo kunye nokubumba ukunyanzeliswa
Ngokuqhelekileyo kusetyenziswa ukucolwa komatshini, i-atomization, iindlela zomzimba kunye neekhemikhali ukulungiselela umgubo.I-powder elungiselelwe i-sieved kwaye ixutywe, izinto ezixutywe ngokufanayo kunye neeplasticizers ezifanelekileyo zongezwa, emva koko zixinzelelwe kwimilo.I-athomu phakathi kwamaqhekeza e-powder i-slid-phase diffusion kunye ne-mechanical occlusion, ukwenzela ukuba iindawo zidibaniswe ngokupheleleyo kunye namandla athile..Uxinzelelo olukhulu, ubukhulu becala lokuxinana kwenxalenye kunye nokunyuka okuhambelana namandla.Ngamanye amaxesha ukwenzela ukunciphisa uxinzelelo kunye nokwandisa ukuxinana kwamalungu, indlela yokucinezela i-isostatic eshushu ingasetyenziswa.

2. Ukucula
Inxalenye ecinezelweyo ifakwe kwisithando somlilo esivaliweyo kunye nomoya wokunciphisa ukuhlamba, kunye nokushisa kwe-sintering malunga ne-2/3 ukuya ku-3/4 amaxesha okunyibilika kwesiseko sesinyithi.Ngenxa yokusasazwa kweentlobo ngeentlobo zeathom kubushushu obuphezulu, ukuncitshiswa kweeoksidi kumphezulu womgubo kunye nokuphinda kuhlaziywe kwakhona komgubo ogogekileyo, amasuntswana omgubo adityaniswe omnye komnye, nto leyo ephucula amandla emveliso yomgubo wesinyithi kwaye ifumane i-athomu. ulwakhiwo olufana nelo lwealloyi ngokubanzi.Kusekho imingxunyana emincinci kwiindawo ezibolileyo, eziyimathiriyeli enemingxuma.
Isithathu, emva kokulungiswa
Ngaphantsi kweemeko eziqhelekileyo, iinxalenye ze-sintered zinokufikelela ekusebenzeni okufunekayo kwaye zinokusetyenziswa ngokuthe ngqo.Kodwa ngamanye amaxesha, kuyimfuneko emva kokulungiswa.Ngokomzekelo, unyango olucinezela ngokuchanekileyo lunokuphucula ukuxinana kunye nokuchaneka kwe-dimensional yamalungu;Ukucima kunye nonyango lokucima umphezulu kwiindawo zesinyithi ezisekelwe kwisinyithi kunokuphucula iimpawu zabo zoomatshini;ukuntywiliselwa kwe-oyile okanye ukuntywiliselwa ukuthambisa okanye ukumelana nomhlwa.I-lubricant elulwelo;unyango lokungeniswa kokungena kwintsimbi ephantsi yokunyibilika kwimibhobho yecandelo kunokuphucula amandla, ukuqina, iplastiki okanye impembelelo yokuqina kwenxalenye.
Iingxenye ze-metallurgy ze-powder zisetyenziswa ngokubanzi kumashishini ahlukeneyo: imboni yemoto, i-synchronizer hubs, amakhonkco e-synchronizer, iipulleys, i-synchronizers;iibheringi ezahlukeneyo, iigiya zesinyithi somgubo, iindawo zentsimbi, njl.njl. zisetyenziswa ngokubanzi kwimveliso yoomatshini.
