Umthelela wedigri ye-pore kukhwalithi

I-tungsten carbideama-pores ngokuvamile abangelwa ukungcola kubhlokhi engenalutho ngaphambi kokucwiliswa.Ngenxa yokusatshalaliswa okungalingani kwama-pores kusampula, izinkambu ezimbalwa ezengeziwe kufanele zibhekwe.Lapho uthola, ungabheka ngakunye (kusukela emaphethelweni esigaba sesampula ukuya phakathi nendawo).Khetha inkambu ebonakalayo enezimbotshana eziningi uma kuqhathaniswa nesithombe esijwayelekile se-GB/ T 3489-1983 porosity.I-GB/T3489-1983 pore degree picture ihlukaniswe ngamazinga ayi-11, futhi i-pores yayo i-0.1%, 0.2%, 0.4%, 0.6%, 0.8%, 1.0%, 1.2%, 1.4%,

I-Tungstenamabhlogo we-carbidengemva kokupholishwa isampula zibhekwa izikhathi 100, futhi usayizi mkhulu noma ulingana 25 μm.Imbobo emnyama enezimo ezingavamile kodwa imiphetho ecacile ibizwa ngokuthi ukungcola.Kuwuthuli noma okunye ukungcola kwabantu okuxubenei-tungsten carbideimpushana kanye nenqubo yokucindezelwa, kanye nezimbobo ezinciphayo ezishiywe ngokuncipha ngemva kokucwiliswa.Ubude obuphelele bakho konke ukungcola endaweni yokupholisha isampula kubizwa ngokuthi ukungcola.
