Pores ma hope o ka Sintering

ʻO ka carbide Cemented he ʻano hui pū ʻia me ka tungsten like a me ke kalapona, kahi paʻakikī kokoke i ke daimana. He kiʻekiʻe ka paʻakikī a me ka paʻakikī kiʻekiʻe i ka carbide Cemented i ka manawa like. Hana ʻia ka carbide cemented e ka pauka metallurgy, a ʻo ka sintering ka hana koʻikoʻi i ka wā e hana ana i kahi huahana carbide cemented. He mea maʻalahi ke hana i nā pores ma hope o ka tungsten carbide sintering inā ʻaʻole i mālama pono ʻia. Ma kēia ʻatikala, e loaʻa iā ʻoe kekahi ʻike e pili ana i nā pores ma hope o ka sintering carbide tungsten.

Hoʻohui ʻia ka pauka tungsten carbide a me ka pauka binder i kekahi ʻāpana. A laila, hana ʻia ka pauka hui ʻia i ʻōmaʻomaʻo ma hope o ka wili pulu ʻana i loko o ka mīkini wili pōleʻa, ka hoʻomaloʻo ʻana, a me ka paʻi ʻana. Hoʻopiliʻia nā'ōmaʻomaʻo'ōmaʻomaʻo tungsten carbide i loko o kahi kapuahi HIP sintering.

Hiki ke hoʻokaʻawale ʻia ke kaʻina hana sintering i ʻehā mau pae. ʻO ia ka wehe ʻana o ka mea hoʻoheheʻe ʻia a me ka pae pre-sintering, ke kahua sintering solid-phase, ka pae hoʻoheheʻe wai-phase, a me ka pae hoʻoilo hoʻoilo. I ka wā o ka sintering, piʻi mālie ka mahana. Ma nā hale hana, ʻelua mau ala maʻamau no ka sintering. ʻO kekahi o ka hydrogen sintering, kahi e hoʻomalu ʻia ai ka haku ʻana o nā ʻāpana e nā kinetics reaction reaction ma ka hydrogen a me ke kaomi o ka lewa. A ʻo ka mea ʻē aʻe, ʻo ia ka sintering vacuum, kahi e hoʻohana ai i kahi kaiapuni a i ʻole kahi wahi i hoʻemi ʻia. Na ke kinoea e hoʻomalu i ka hana carbide cemented ma ka hoʻolohi ʻana i nā kinetics.

Ke mālama pono nā limahana i kēlā me kēia pae, hiki i nā huahana hope loa o ka tungsten carbide ke loaʻa i ka microstructure a me ka haku mele. Aia paha kekahi pores ma hope o ka sintering. ʻO kekahi o nā kumu nui e pili ana i ka mahana sintering. Inā piʻi wikiwiki ka mahana, a i ʻole ke kiʻekiʻe o ka mahana sintering, ʻaʻole kūlike ka ulu ʻana o ka palaoa a me ka neʻe ʻana, e hopena i ka hana o nā pores. ʻO kekahi kumu koʻikoʻi ʻo ia ka mea hana. Pono e wehe ʻia ka mea hoʻopili ma mua o ka sintering. A i ʻole, e volatilize ka mea hana i ka wā o ka hoʻonui ʻana i ka mahana sintering, kahi e hopena ai i nā pores.

Inā makemake ʻoe i nā huahana tungsten carbide a makemake ʻoe i ka ʻike hou aʻe a me nā kikoʻī, hiki iā ʻoe ke CONTACT US ma ke kelepona a i ʻole leka uila ma ka hema, a i ʻole SEND US MAIL ma lalo o ka ʻaoʻao.
