ʻO ke ola lawelawe o kapahi hāmarepili i ka mea o ka pahi hāmare ponoʻī, ke ʻano o ka mea i kuʻi ʻia, a pēlā aku. ʻO ka mea o ka pahi hāmare ka mea nui e pili ana i kona ola. Ua māhelehele ʻia nā pahi hāmare ma ka mākeke i ʻekolu mau ʻāpana: nā pahi hāmare maʻamau, nā pahi hāmare tungsten carbide spray welded, a me nā pahi hāmare tungsten carbide fusion welded.
I waena o lākou, inā he ʻāpana hāmare i mālama ʻia i ka wela ka ʻāpana hāmare maʻamau, a i ʻole he ʻāpana hāmare kila 65Mn wale nō e hoʻohana ʻia, ʻoi aku ka haʻahaʻa o ke kumukūʻai o kēia ʻano hāmare, akā ʻoi aku ka pōkole o ke ola lawelawe e pili ana.
Hoʻohana nui ʻia nā hāmare hoʻoheheʻe ʻōpala tungsten carbide ma ka mākeke, me ka hoʻohana ʻana i ka ʻenehana hoʻoheheʻe ʻōpala oxyacetylene e pīpī i ka pauka tungsten carbide ma luna o ka substrate hāmare, a laila mālama wela i ka hāmare e hana i ka huahana hope loa. Eia nō naʻe, ma muli o ke kaiapuni hana ʻino a me ka mana o ka maikaʻi o ke kaula hoʻoheheʻe tungsten carbide, ʻaʻole like ka maikaʻi o ka hāmare tungsten carbide hope loa, pinepine ʻia me nā hemahema e like me nā pores a me nā hoʻokomo ʻana i loko o ka papa weld, e hoʻopilikia nui ana i kona ola lawelawe. ʻOi loa i ka wā e haki ai nā mea paʻakikī iki, maʻalahi ke kumu o ka hiolo ʻana o ka papa weld. Eia kekahi, hele pū ke kaʻina hana me ka nui o ka lepo a me nā kinoea ʻino, ʻaʻole hiki ke hoʻokō i ka automation, a ʻaʻole hoʻohiki nui nā manaʻolana.
Hoʻohana nā hāmare wiliwili tungsten carbide fusion a HMT i ka ʻenehana hoʻopili wiliwili plasma, kahi e waiho ai i kahi papa o nā ʻāpana alloy paʻakikī ma luna o ka substrate hāmare, e hoʻokō ana i ka mānoanoa like ma waena o ka substrate hāmare a me ka papa wiliwili alloy paʻakikī. I ka manawa like, loaʻa i kēlā me kēia ʻāpana alloy paʻakikī kahi ʻoi ʻoki multi-directional, e hoʻonui nui ana i ka hana shear o ka hāmare. Loaʻa i nā ʻāpana hāmare wiliwili fusion paʻakikī a HMT ka hana maikaʻi loa, me ke kūpaʻa ʻana i ka ʻaʻahu kiʻekiʻe, ke ola lawelawe, ke kūpaʻa hopena, a me ka pono o ka haki ʻana i hoʻohālikelike ʻia me nā ʻāpana hāmare spray welded tungsten carbide. Eia kekahi, hiki ke hana ʻakomi ʻia ke kaʻina hana a pili i ke kaiapuni, e lilo ia i mea i ʻano hana i ka hana ʻāpana hāmare hou.
He hopena koʻikoʻi nō hoʻi ka wāwahi ʻana i nā mea i ke ola lawelawe o nā hāmare, a ʻo ka hoʻohana ʻana i nā hāmare like ʻole e wāwahi i nā mea like ʻole hiki ke hoʻomaikaʻi nui i ka pono o ka wāwahi ʻana. He paʻakikī kiʻekiʻe kekahi mau mea, no laila he ikaika loa ka ikaika o ka hopena ma ka hāmare. No ka laʻana, i ka wā e haki ai ka hānai ʻohe a me ka hāmare wiliwili tungsten carbide, hiki ke hiolo ka papa wiliwili. No nā mea me ka ʻaʻahu nui, pono e hoʻonui ʻia ka lōʻihi o ka papa pale ʻaʻahu e 100mm, e like me ka hānai ʻili palaoa. Aia kekahi ʻano o nā poloka lāʻau i wāwahi ʻia, nona ka ikaika hopena kiʻekiʻe a me ka ʻaʻahu, a ʻaʻole hiki ke hoʻohana ʻia nā hāmare wiliwili tungsten carbide. No nā hāmare maʻamau, he pōkole ko lākou ola lawelawe. No ka wāwahi ʻana i ia mau mea, hiki i nā hāmare wiliwili fusion alloy paʻakikī a HMT ke hoʻokō maikaʻi i nā koi. Ma hope o ka hoʻohana pono ʻana e ka mea hana o nā poloka lāʻau i wāwahi ʻia, ua hōʻoia ʻia e hiki i nā hāmare wiliwili fusion alloy paʻakikī a HMT ke hoʻokō maikaʻi i nā koi. Eia kekahi, he hopena koʻikoʻi nō hoʻi ka nui o ka makū o ka palaoa i ka pono o ka wāwahi ʻana. Ke kiʻekiʻe ka nui o ka makū, nui ka ʻaʻahu o ka hāmare a pōkole ke ola lawelawe.
