Nā mākau wili wili titanium

• (1) Ma muli o ke kūpaʻa ʻole o kāna ʻano kemika. E hana ka TC4 titanium alloy me ka oxygen a me ka nitrogen ma lalo o ka deformation thermal, a ʻoiai me kekahi kinoea i loaʻa ka oxygen, e hoʻopuka ka hopena i ka pālākiō oxide i hoʻopili ʻia i ka papa hana, inā ʻoi aku ke kiʻekiʻe o ka mahana, hiki i 900 ℃ I ka manawa i luna, nā unahi i hoʻopili ʻia i ka ʻili o ka mea hana e hana i nā unahi, i mea e komo ai ka oxygen a me nā mea nitrogen i loko o ka mea hao a hana a pae i ka ʻili getter layer. ʻO ka paʻakikī kiʻekiʻe a me ka plasticity haʻahaʻa nā ʻano o kēia papa getter.
• (2) No ka compound Fe-C paʻakikī ka hana o ka simaite i loko o ka metala metallographic, a hiki ke kiʻekiʻe ka paʻakikī o Vickers i ka HV1100, akā aneane ʻole ka paʻakikī paʻakikī.
• (3) ʻAʻole kiʻekiʻe ka conductivity thermal: inā hoʻohālikelike ʻia ka conductivity thermal o ka titanium alloy me nā mea hana ʻē aʻe e like me ke kinikini alumini, aia wale nō ma 1/15 o kēlā me nā ʻāpana alumini a me 1/5 o kēlā kila. Hoʻohālikelike ʻia me ke kinikini aluminika a me ke kila, ʻoi aku ka haʻahaʻa o ka conductivity mehana a me ka conductivity mehana o ke aneto titanium, ma kahi wale nō o 1/15 o ke kinikini aluminika, a ma kahi o 2/7 o ke kila. ʻO ka hopena o ka maikaʻi o ka ʻilikai o kahi o nā ʻāpana oka oka titanium kahi nui.

ʻO nā pilikia nui i kū i ka wili ʻana o ka oka a titanium

• (1) He koʻikoʻi ka pilikia pili paʻa o ka wili wili. Hoʻopili ke kinikini titanium i ka ʻili o ka wili wili, a ʻo ka pae o ka hoʻopili e like me ka uahi. ʻO ke kumu nui o ka hāʻule ʻana o ka mea adhesion i ka wā o ka wili ʻana. ʻO kēia ka mea e hāʻule ai nā mea ʻino abrasive a me ka haki, kahi e hōʻino loa ai i ka huila wili.
• (2) ʻOi aku ka nui o ka ikaika wili a ʻoi aku ka kiʻekiʻe o ka mahana o ka wili. I ka wā o ka wili hoʻokolohua ʻana o nā huna puʻupuʻu abrasive, ua ʻike ʻia i ka wā e wili ana i nā kolamu titanium, ʻo ka hapa nui ka hana e heʻe ai, a ʻo ka manawa pili o nā ʻāpana abrasive a he pōkole loa ka mea hana, i ka manawa o ka hakakā ikaika loa a me ka elastis ikaika a me ka deformation ea, a laila lepo ka titanium oka a i loko o nā ʻāpana, kahi e hoʻoulu ai i ka wela wili, i kēia manawa hiki i ka mahana o ka wili a kokoke i 1500 ℃.
• (3) E hua ana ka wili palaoa i nā ʻāpana kaomi, ʻo ke kumu nui ka deformation paʻakikī. Hoʻokumu ʻia ka ʻāpana āpana like ke hoʻohana ʻia ka wili keʻokeʻo keʻokeʻo keʻokeʻo (WA60KV) e wili ai 45 kila, a hana ʻia nā ʻāpana huʻihuʻi ʻia i ka wā e hoʻohana ʻia ai ka huila silicon carbide wili palaoa (GC46KV) e wili ai i ka hao titanium.
• (4) Ma lalo o ke kūlana wela kiʻekiʻe, ka hana kemika o ka mīkini TC4 titanium ʻeleu a paʻa ka hana pono, a maʻalahi hoʻi e hui pū me ka oxygen, nitrogen, hydrogen a me nā mea ʻē aʻe i ka lewa e hana i kahi hopena kolohe e hana i ka palupalu a paʻakikī e like me ka titanium dioxide, titanium nitride, titanium hydride Metamorphic layer, i hiki ai i hoʻemi i ka plasticity o TC4.
• (5) I ka wā o ka wili ʻana o nā oka a ka titanium, hoʻopili ʻia ia e nā pilikia paʻakikī, ʻo ka mea nui no ka mea he mea paʻakikī ka lawe ʻia ʻana o ka wela i loko o ka mea hana, a maʻalahi ka hana ʻana o ka mea hana, puhi ʻia, a ʻo kekahi mau māwae ke hōʻike. No laila, ka papa o ka workpiece E ʻokoʻa ana nā kekelē o ka ʻākala.

Nā hana kaomi e hoʻonā i ka wili ʻana o ka wela a me nā māwae

Aia kekahi mau pilikia i ka mīkini ʻana i ka TC4 titanium alloy me nā wili wili. ʻO ka pilikia ʻoi aku ka nui o ka hoʻopili ʻana. Ma muli o ka wikiwiki, kiʻekiʻe ka ikaika o ka wili a me ka mahana, kahi e puhi ai i ka papa a hana i nā māwae. Ua hana ʻo Ren Jingxin a me nā poʻe ʻē aʻe i kahi noiʻi hoʻokolohua e hoʻoliʻiliʻi i nā lapalapa a me nā māwae i ka wā o ka mīkini. Manaʻo lākou hiki ke hoʻohana ʻia nā huila wili palupalu, e like me kahi o nā huila wili corundum, ma kahi o ka silicon carbide a i ʻole nā ​​celium silicon carbide wili huila, corundum wili wili Resin adhesion, ʻoiai ka mea ma mua e hoʻohana i ka ceramic adhesion. E nānā pono hoʻi i ka mīkini cnc mua ʻo nā laʻana, no ka laʻana, ʻaʻole wikiwiki ka wikiwiki o ka wili wili, ʻaʻole ʻoi aku ka loiloi o ka hoʻokolohua hoʻokolohua ma mua o 20 mau mika no kekona, ʻaʻole e ʻoi aku ka hohonu o ka wili, ʻaʻole pono e ʻoi aku i ka 0.02 millimeter. I loko o kēlā me kēia minuke, ʻaʻole pono ka waipū wili e hoʻopau pono i ka wela, akā e hoʻokūkala hoʻi i ka hopena lubrication, kahi e hiki ai ke kaomi pono i ka hanana o ka paʻa. Inā maloʻo ia e wili, hiki ke hoʻoulu ʻia ka mea lubricant me ka lubricant paʻa wili Impregnated wili.

Ke wili nei i nā mea paʻa i ka wili i ka wili oka a me nā ana e kaohi ai

Ma muli o ke kaʻina wili ʻana o ka oka a ka titanium, e nui aʻe ana ka mahana o ka wili ʻana a me ka ikaika maʻamau maʻamau, no laila e hana ʻia ka loli palekika koʻikoʻi i ke kinikini titanium i ka wili wili, ma waena o ka abrasive a me ka metala ʻO ka hopena adsorption i hoʻokumu ʻia e kemika a i ʻole kemikala adsorption; ke kumu o ka hoʻoneʻe ʻana o ka mea hao honua i nā ʻāpana abrasive ka hopena o ka ikaika hoʻopaʻa, e alakaʻi ai i ka hoʻopaʻa ʻana o ka huila wili. ʻO ka hope loa, haki nā ʻāpana abrasive, a i ka wā i ʻoi aku ka ikaika o ka wili ʻana i ka ikaika paʻa ma waena o nā huna mea abrasive, e hemo nā huehue abrasive a me ka mea hoʻopaʻa mai ka wili wili.

ʻO ka wili wikiwiki a me ka maikaʻi

Ua hana kekahi mau ʻepekema i ka wikiwiki a me ka maikaʻi o ka wili ʻana o nā mea hao TC4 titanium. I ke aʻo ʻana, pili ka lula i ka mana o ka wili ʻana i kēlā me kēia ʻāpana a me ka ikehu wili e ka nui o ka wili. Inā piʻi ka wikiwiki o ka laina a me ka wili wili, ʻo ka ikaika o ka wili no kēlā me kēia ʻāpana e hoʻemi nui. Eia nō naʻe, ke piʻi ka wikiwiki o ka papa ʻaina a me ka hohonu o ka wili ʻana, piʻi ka ikaika o ka wili i kēlā me kēia ʻāpana. Inā piʻi ka wikiwiki linear vs. o ka wili wili, e hoʻonui ʻia ka ikehu wili, akā inā piʻi ka wikiwiki o ka papa ʻaina a hoʻonui ka hohonu o ka wili, e emi ka ikehu wili.
