Amalungu angeniswa ngobhedu ngenxa yezizathu ezininzi.Ezinye iziphumo ezinqwenelekayo ezisisiseko kukuphuculwa kokuqina kokuqina, ubunzima, iipropathi zempembelelo, kunye ne-ductility.Amacandelo afakwe ubhedu nawo aya kuba noxinzelelo oluphezulu.
Ezinye izizathu ezinokubangela ukuba abathengi bakhethe ukungena ngobhedu kukuphucula ukunxiba okanye ukuvala ukuhamba komoya / irhasi ngecandelo elinobuqhophololo kumaqondo obushushu anokuthi intlaka ingasebenzi.Ngamanye amaxesha ukungena kobhedu kusetyenziselwa ukunyusa iimpawu ze-machining zensimbi ye-PM;ubhedu lushiya isiphelo esigudileyo esenziwe ngoomatshini.
Nantsi indlela ukufakwa kobhedu kusebenza ngayo:
Isiseko sesiseko secandelo sinoxinaniso olwaziwayo, olusetyenziselwa ukugqiba inani le-porosity evulekile.Umlinganiselo olinganisiweyo wobhedu ukhethiweyo uhambelana nomlinganiselo we-porosity oza kugcwaliswa.Ubhedu luzalisa i-porosity ngexesha lenkqubo ye-sintering (kwiqondo lokushisa elingaphezulu kweqondo lokushisa lokunyibilika kobhedu) ngokubeka nje ubhedu malunga necandelo ngaphambi kokutshisa.Ubushushu be-2000 ° F sintering buvumela ubhedu olutyhidiweyo ukuba lungene kwi-porosity yecandelo ngokusebenzisa i-capillary action.I-Sintering igqityiwe kwi-carrier (umz. ipleyiti ye-ceramic) ngoko ubhedu luhlala kwindawo.Emva kokuba inxalenye ipholile, ubhedu luqiniswa ngaphakathi kwesakhiwo.
