Ukungqubana phakathiukwenzakukukhuhlana phakathi kweentsimbi ezimbini zokwakheka ezahlukeneyo kunye neempawu (ialloyi), phakathi kwentsimbi ethambileyo (isixhobo sokusebenza) kunye nentsimbi eqinileyo (die). Kwimeko yokungabikho kokuthambisa, kukukhuhlana koqhagamshelwano lweentlobo ezimbini zefilimu ye-metal surface oxide; Ngaphantsi kwemeko yokuthambisa, ingxabano yoqhagamshelwano phakathi kwefilimu ye-oxide kwiindawo ezimbini zetsimbi kunye ne-lubricating medium ngokulandelanayo, kunye ne-friction phakathi komphezulu womgangatho wangaphakathi we-workpiece, engekafakwa i-oxidized kwaye inamandla amakhulu e-adsorption, kunye nengxabano phakathi kwendawo yokuthambisa kunye nomphezulu we-die kunye neyona ndawo ye-friction (yokuqhagamshelana) iyanda.
Ngenxa yeempawu zokukhuhlana phakathi kokungenanto kunye nomphezulu woqhagamshelwano wokufa kwiinkqubo yokubumba, iziphumo ezilandelayo ziya kubangela:
(1) Amandla okuguqula anyuka nge-10% ngenxa yengxabano, kwaye ukusetyenziswa kwamandla kunyuka ngokufanelekileyo;
(2) ukungqubuzana kukhokelela ekuguqulweni okungalinganiyo kwe-forgings, ukwenzela ukuba ukwakheka kweenkozo zangaphakathi kunye nokusebenza akufani, kwaye umgangatho womphezulu uyancipha;
(3) ukungqubana kukhokelela ekuncitshisweni kobume bejometri kunye nokuchaneka kobukhulu be-forging, nto leyo ekhokelela kwi-scrap of forgings xa i-forging ingagcwaliswa ngokunzulu;
(4) ungquzulwano lukhokelela ekugugeni okumandundu kwefa kwaye kunciphisa ubomi bayo;
(5) Ukwandisa ukuchasana kwe-friction yendawo ye-cavity kungenza umgodi onzima ukugcwalisa isinyithi ngokufanelekileyo kunye nokunciphisa izinga lokwenqaba.
Kuyabonakala ukuba ukukhuhlana likrele elintlangothi-mbiniimveliso yokubumba, eneengenelo nezingeloncedo. Ngoko ke, ukukhuhlana kwinkqubo yokubumba kufuneka ilawulwe ngokungqongqo ukuqinisekisa ukuba inkqubo yokufota eqhelekileyo.
