Izingxenye Zesakhiwo Se-Powder Metallurgy

Incazelo emfushane:

Lokhu kuhlobene nomkhakha okhethekile we-powder metallurgy, njengoba ukuminyana, i-porosity, izinto zokwakha kanye nezindlela zokwelapha ukushisa kwamagiya e-powder metallurgy kuthinta ngokuqondile ubulukhuni namandla. impahla, ukuqina okuphezulu.Izindlela zokwelapha ukushisa ngokuvamile zihlanganisa ukucima i-carburizing, i-carbonitriding, i-high frequency quenching, i-low frequency quenching, ukucima uwoyela, njll.Inqubo yokucisha eqinile futhi efanelekayo igcina ubulukhuni bokwelashwa kokushisa buzinzile.

Ukuminyana kwempushana ye-athomu evamile (okuhlanganisa insimbi ye-carbon nensimbi ye-copper-carbon alloy) kungaphezu kuka-6.9, futhi ubulukhuni bokucisha bungalawuleka eduze kwe-HRC30.

Ngokuvamile, ukuminyana kwe-powder pre-alloyed (AB powder) kudlula i-6.95, futhi ubunzima bokucima bungalawulwa eduze kwe-HRC35.

Izimpushana eziphezulu ezifakwe ngaphambili ezinobuningi obukhulu kuno-6.95 kanye nobulukhuni bokucisha okulawulwa ku-HRC40.

Imikhiqizo ye-powder metallurgy eyenziwe ngezinto ezingenhla inokuqina okuzinzile kanye nezinto ezibonakalayo, futhi ubulukhuni ngemva kokwelashwa kokushisa buhlangabezana nezidingo ezihambisanayo, ngakho amandla abo okuqina namandla okucindezela azofinyelela esiqongweni esingcono.

Ingabe ubulukhuni bokwelashwa kokushisa kwe-powder metallurgy bufinyelela insimbi engu-45? Yebo ungakwazi!

Kodwa-ke, ngenxa yokuthi ukuminyana kwemikhiqizo ye-PM akuphakeme njengaleyo yensimbi enguNombolo 45, ukuminyana okuphezulu kakhulu kwezingxenye zokucindezela ze-PM kuvamise ukuba ngu-7.2 g/cm, kuyilapho ukuminyana kwensimbi engu-No. 45 kungu-7.9 g/cm.I-Carburizing ephoqelelwe i-powder metallurgy noma ukwelashwa kokushisa okuvama kakhulu okudlula i-HRC45 kuzokwenza imikhiqizo ye-powder metallurgy ibe brittle ngenxa yokucisha okukhulu, okuholela emandleni emikhiqizo ye-powder metallurgy.

Okulandelayo, sizoqhathanisa igiya lokwakha i-P/M negiya lokuhobha elinomshini.

1. Izinga eliphezulu lokusebenzisa impahla, kuze kufike ngaphezu kwama-95%

2. Cha noma ukusika kancane kuyadingeka

3. Ukungaguquguquki okuhle kwezingxenye, ukuzinza okuhle nokunemba okuphezulu.

4. Ukuqhathanisa amandla: abakhiqizi bensimbi abayizimpushana abachwepheshile bathuthukise ukwakheka kwesikhunta se-powder metallurgy, futhi amandla aqinile namandla acindezelayo egiya akhiqizwayo asondelene nalawo okubhoboza igiya.Isibonelo, igiya elishayelwa igiya lemoto elinokuhanjiswa okuphezulu. ukuqina futhi kuyigiya le-powder metallurgy.Igiya elibonakalayo, i-powder metallurgy liyasebenza futhi libanzi.

5. Ukucindezela i-Powder usebenzisa ukubunjwa kwesikhunta, kungakhiqiza obunye ubuchwepheshe bokusika be-hobbing abukwazi ukukhiqiza izimo eziyinkimbinkimbi.

6. Ngenxa yokuthi ifanele ukukhiqizwa ngobuningi, ukusebenza kahle kokukhiqiza kuphezulu futhi izindleko ziphansi kunokusika.

7. Ifanele ukukhiqizwa ngobuningi, ngakho intengo iyancintisana ngokuphelele.
