ʻO nā mea abrasive o ka pōhaku wili

ʻO ka pōhaku wili pōhaku maʻamau i hoʻohana ʻia no ka corundum class abrasives (zirconium corundum, brown corundum, white corundum, etc., e like me Figure 11) [1,2] , kekahi super-hard abrasives (CBN) [3] a me SiC, WC, etc. 2P1z mokuʻāina, ʻo ia hoʻi, ka graphitization daimana, hoʻemi i ka hana wili abrasive [4,5] Hoʻemi kēia i ka hana wili o ka abrasive, a no laila ʻaʻole kūpono ke daimana no ka wili ʻana. ʻOiai ʻo CBN abrasive ikaika / paʻakikī, a me ke kiʻekiʻe wela ke kūpaʻa, ʻaʻahu kūʻokoʻa, maikaʻi thermal conductivity, ikaika wili ikaika [6,7] ʻOiai ʻo CBN abrasives he ikaika / paʻakikī, kiʻekiʻe wela ke kūpaʻa, kūʻokoʻa, maikaʻi thermal conductivity, ikaika wili ikaika, akā liʻiliʻi kona ʻāpana nui (ʻo ka nui o ka nui o ka nui ma lalo o 500 μm), ke kumu kūʻai kiʻekiʻe, he mea paʻakikī ke hōʻike ʻana i ka maikaʻi o kēia ʻano. wili a me ka ukana kaumaha, a ilihune ka waiwai o ka pohaku wili. ʻO ka Corundum abrasives maikaʻi ke pale ʻana i ka lole, ikaika / paʻakikī, a me ka hiki ke ʻoki, haʻahaʻa ke kumu kūʻai, i ka papa wili kaʻa o ke kiʻekiʻe kiʻekiʻe, ka ukana kiʻekiʻe, ka wili maloʻo, ka nui o ka palaoa a me nā kūlana hana ʻē aʻe he mau mea maikaʻi ʻole. Zhang Wulin[8] Ua nānā ʻia nā ikaika compressive o zirconium corundum, calcined brown corundum a me keʻokeʻo corundum a me ka hana wili o nā pōhaku wili like o F16 i nānā ʻia me ka hoʻohana ʻana i kahi mea hoʻokolohua uniaxial compression, a ua hōʻike ʻia nā hopena: ʻo ka ikaika o ka zirconium corundum ka mea kiʻekiʻe loa (308.0 MPa. ʻO kahi haʻahaʻa he corundum keʻokeʻo (103.2 MPa); a o na ratio wili o ka zirconium, calcined brown corundum a me keokeo corundum abrasive abrasive pohaku, ma ke ano o ka nui, he 41.0, 22.4, a me 11.9; No laila, hoʻohana mau ʻia nā corundum abrasives ikaika/ʻoʻoleʻa a me ke kemika, ʻoi aku ka zirconium corundum a me ka corundum brown, i ka hana ʻana i nā pōhaku wili kaʻa. I kēia manawa, ʻike ʻia ka ʻenehana hoʻoheheʻe abrasive zirconium corundum kiʻekiʻe o ka honua e Farani Saint-Gobain a me nā ʻoihana ʻē aʻe. No laila, ʻo ka uhaki ʻana i ka bottleneck ʻenehana nui o ka zirconium corundum smelting a me ka hoʻomohala ʻana i ka hana kiʻekiʻe (kiʻekiʻe paʻakikī, pale ʻana i ka wela, ʻoi aku ka maikaʻi ponoʻī, etc.) zirconium corundum abrasives he mea koʻikoʻi no ka hoʻomaikaʻi ʻana i ka hana pōhaku wili.

I kēia manawa, hana ʻia nā pōhaku wili no ka wili laina laina me ka hui ʻana o nā abrasive o nā ʻano nui a me nā ʻano like ʻole. Wang et al.[50] ua aʻo i ka hana wili pōhaku me nā lakio like ʻole o ka zirconium corundum a me ka brown corundum, a ua hōʻike nā hopena me ka piʻi ʻana o ka maʻiʻo corundum brown (0% ~ 100%), ua emi ka nui o ka wili pōhaku. Hōʻike nā hopena hoʻohālikelike piha i ka hoʻohui ʻana o 10% ~ 30% o ka corundum brown i ka pōhaku ʻala e hiki ke hōʻoia i ka ʻoi aku ka maikaʻi o ka wili ʻana a me ka hoʻohaʻahaʻa ʻana i ke kumukūʻai hana o ka pōhaku ʻala.Zhang et al.[11] ua noiʻi i ka hana wili ʻana o nā pōhaku wili me nā ʻano nui o ka palaoa abrasive (F10~F30), a ua hōʻike ʻia nā hopena ma lalo o kekahi haʻawe, me ka hoʻemi ʻana o ka nui o ka palaoa abrasive, ua hoʻololi mālie ke ʻano o ka wili ʻana o ka pōhaku mai ka paheʻe ʻana a me ka palau ʻana a hiki i ka ʻoki ʻana, a ʻo ka hana ʻana o ka wili pōhaku i hoʻomaikaʻi ʻia ka maikaʻi o ka pōhaku wili. Ma ka haʻawina ma hope, Zhang et al.[1] ua hoʻomau i ke aʻo ʻana i nā ʻano mechanical o ka zirconium corundum, brown corundum a me keʻokeʻo corundum abrasives a me ka hana wili ʻana o ka pōhaku ʻala e pili ana, a ua hōʻike ʻia nā hopena i nā ʻano mechanical o nā abrasives kekahi o nā kumu kumu e pili ana i ka hana wili ʻana o ka whetstone. Wang et al.[12] Ua hōʻike ʻia nā hopena o ke aʻo ʻana ua piʻi ka haʻalulu wili me ka emi ʻana o ka nui o ka palaoa o ka abrasive pōhaku wili. ʻOiai ua hana ʻia ka nui o nā hana noiʻi e pili ana i ka wili pōhaku abrasives, ʻo ke ʻano hoʻoponopono o ke ʻano abrasive (geometry, type, grain size, ratio, etc.) ma ke kino a me nā waiwai kemika o ka pōhaku wili (toughness/toughness, strength, heat resistance, wear resistance, etc.) ma hope o ka wili ʻana) ʻaʻole maopopo.
