Umbuzo 5: Ngaba ukunyibilikisa izinto ezingcolisayo kunobuhlobo nokusingqongileyo kunokunyibilikisa?

Ngaba ukunyibilikisa izinto ezingcolisa umoya kunobuhlobo nokusingqongileyo kunokunyibilikisa?

Ngokubanzi, ewe. Ukucocwa kwenkunkuma kudla ngokuthathwa njengokuzinzileyo kuba:

*Ifuna amaqondo obushushu aphantsi okucubungula

*Isebenzisa amandla amancinci

*Ivelisa izinto ezilahliweyo nezingafunekiyo kakhulu

*Isebenzisa imveliso ephantse ibe nomfanekiso we-net

Iinkqubo zemveli zokunyibilikisa zifuna ubushushu obuphezulu kwaye zihlala zibandakanya umatshini wesibini

amanyathelo avelisa izinto ezilahlwayo.

Ukunyibilikisa umgubo kuphucula ukusetyenziswa kwezinto kwaye kunokuxhasa iinjongo zokuvelisa eziluhlaza.

Umbuzo 6: Ngaba ukunyibilikisa izinto ezinyibilikisayo kungathabatha indawo yokunyibilikisa kuzo zonke izicelo zesinyithi?

Ngaba ukunyibilikisa izinto ezisetyenziswayo kungathabatha indawo yokunyibilikisa kuzo zonke izicelo?

Hayi. Ukunyibilikisa nokusila kuhlangabezana neemfuno ezahlukeneyo zokuvelisa kwaye kuyahambelana

endaweni yokutshintshana.

Ukunyibilikisa kubalulekile kwi:

*Iinxalenye ezinkulu zesakhiwo
*Iindibano ezidityanisiweyo
*Izicelo ezifuna ukuguquguquka okuphezulu

Ukusinta kulungele:

*Iinxalenye zokuchaneka
*Iinxalenye ezisebenzayo ezinemingxuma
Iimveliso ezisemgangathweni eziphezulu

Ukukhetha phakathi kwazo kuxhomekeke kwijiyometri, iimfuno zokusebenza, kunye neethagethi zeendleko.

Umbuzo 7: Yeyiphi inkqubo enika ukuchaneka okungcono kobukhulu?

Yeyiphi inkqubo enika ukuchaneka okungcono kobukhulu: ukunyibilikisa okanye ukunyibilikisa?

Ukusinta ngokubanzi kunika ulawulo olungcono lwemilinganiselo kwiindawo ezincinci nezintsonkothileyo ngenxa yezi zinto zilandelayo:

*Iimodeli ezichanekileyo

*Ukuguquguquka okulinganiselweyo ngexesha lokufudumeza

*Ukwenziwa kwemveliso ekufutshane ne-net-shape

Ukunyibilika nokuphoswa kunokubangela ukushwabana kunye nokuphazamiseka ngexesha lokuqina,

kudla ngokufuna umatshini owongezelelweyo ukuze kufezekiswe ukunyamezelana okuqinileyo.

Oku kwenza i-sintering ifaneleke ngakumbi kwiisensa, izinto zonyango, kunye neendawo ezincinci zoomatshini.

Umbuzo 8: Zihluke njani izakhiwo ezincinci phakathi kweentsimbi ezitshisiweyo nezinyibilikisiweyo?

Izakhiwo ezincinci zahluke njani phakathi kweentsimbi ezisinkiweyo nezinyibilikisiweyo?

Iintsimbi ezisinkisiweyo zenziwe ngamasuntswana omgubo adibeneyo anemida elawulwayo phakathi kwamasuntswana

kunye nokuvuleka okunganyanzelekanga. Ulwakhiwo lwazo oluncinci lunokwakhiwa ukuze kufezekiswe ukuhamba okuthile,

ukuhluza, okanye iimpawu zoomatshini.

Iintsimbi ezinyibilikisiweyo ziyaqina xa zisuka kwimeko yolwelo kwaye zihlala zenza iinkozo ezinkulu ezinezakhiwo eziqhubekayo.

Nangona oku kunokubonelela ngamandla amakhulu obuninzi, akunazo iindlela eziguquguqukayo ze-microstructure ezifana ne-powder metallurgy.

Lo mahluko ubalulekileyo uchaza isizathu sokubai-powder metallurgy vs ukunyibilika kwendabukoiqhubela kwi

ukusebenza kwezinto ezahlukeneyo kunye namathuba okusetyenziswa.
