Ka hopena o ka pore degere ma ka maikaʻi

ʻO ka tungsten carbideʻO nā pores ma muli o nā haumia i loko o ka poloka hakahaka ma mua o ka sintering.Ma muli o ka puʻunaue like ʻole o nā pores i ka hāpana, pono e nānā ʻia kekahi mau māla.I ka ʻike ʻana, hiki iā ʻoe ke nānā i kēlā me kēia (mai ka lihi o ka ʻāpana hoʻohālike a i ke kikowaena).E koho i ke kahua ʻike maka me ka nui o nā pores i hoʻohālikelike ʻia me ke kiʻi maʻamau o GB/T 3489-1983 porosity.GB / T3489-1983 pore degere kiʻi ua maheleia i 11 pae, a me kona pores helu no 0.1%, 0.2%, 0.4%, 0.6%, 0.8%, 1.0%, 1.2%, 1.4%,

Tungstencarbide polokama hope o ka poli ʻana, ʻike ʻia ka hāpana ma 100 mau manawa, a ʻoi aku ka nui ma mua o 25 μm.ʻO ka lua ʻeleʻele me nā ʻano like ʻole akā ua kapa ʻia nā ʻaoʻao māmā he lepo.ʻO ia ka lepo a lepo ʻē aʻe paha o ka poʻe i ka hui ʻana otungsten carbideka pauda a me ke kaʻina hana hoʻopaʻa ʻana, a me nā puka liʻiliʻi i waiho ʻia e ka emi ʻana ma hope o ka sintering.Ua kapa ʻia ka lōʻihi o ka lepo a pau ma luna o ka ʻili poli polū.
