Isiphumo sesidanga se-pore kumgangatho

I-tungsten carbideiipores ngokubanzi zibangelwa bubumdaka kwibhloko engenanto phambi kokuba sintering.Ngenxa yokusabalalisa okungafaniyo kwee-pores kwisampuli, kufuneka kujongwe amasimi ambalwa.Xa ubhaqa, unokujonga nganye nganye (ukusuka kumda wecandelo lesampulu ukuya kwiziko).Khetha eyona ndawo ibonakalayo enezona pores ezininzi xa kuthelekiswa ne-GB/ T 3489-1983 porosity standard picture.I-GB / T3489-1983 umfanekiso we-pore degree ihlulwe ngamanqanaba e-11, kwaye i-pores yayo i-akhawunti ye-0.1%, 0.2%, 0.4%, 0.6%, 0.8%, 1.0%, 1.2%, 1.4%,

Tungsteniibhloko carbideemva kokupholisa isampuli zibonwa ngamaxesha angama-100, kwaye ubukhulu bukhulu okanye bulingana ne-25 μm.Umngxuma omnyama onemilo engaqhelekanga kodwa imiphetho ecacileyo ibizwa ngokuba bubumdaka.Luthuli okanye olunye ukungcola kwabantu abakumxube wetungsten carbideumgubo kunye nenkqubo yokucinezela, kunye nemingxuma eyanciphayo eshiywe ngokucutheka emva kokucima.Ubude obupheleleyo balo lonke ukungcola kwisampulu yokupolisha kumphezulu kuthiwa bumdaka.
