High māmā kila. Kona waiwai a me ka Mea Maluna

Kēia manawa, kiʻekiʻe-ka māmā holo kila mau ia e na alakai mea no ka? Iecaianoaaiiie o na mea hiki ke hooheheeia nozzles a me ka ohi kila. Oia oka mea pinepine ia i loko o ka hana o ka mīkini pahi olo,? Eou, a? Eou hana poo. I loko nō e hōʻike 'ano he ākeaʻano o nā mea a pau ano o ka lepo pipili no hoi carbide a me ka pālolo lua lako e hoʻolako i oi aku aaioee hana ana, kiʻekiʻe-ka māmā holo kila steels paa paʻa ko lakou wahi.

I ka laha ana o na oka a no ka? Iecaianoaaiiie o ka luna '-ʻoki mea paahana aie i kekahi hui malu pu ana i loko i kiʻekiʻe ikaika (mai ka 68 HRC) a me ka thermal kumupaʻa (ka mea, e i lilo aku i ko lakou hana waiwai, a hiki i ka wela o ka 650 ° C) me ke kiʻekiʻe (viscosity) waiwai, mamao e oi aku ana o ka carbide lua lako . A, kiʻekiʻe-ka māmā holo kila i hōʻike kiʻekiʻe adaptability, i mea maikai workability a me ka ana kaʻina puʻe.

He aha ka waiwai e i like me ka oka a mea e kaukaʻi ma alloying hehee wale. Nō kāu, kiʻekiʻe-mämä holo kila mea he multicomponent'ōnaehana i loaʻa ka chromium, molybdenum, tungsten, cobalt, a me ka vanadium. Ke alo aku o na eiiiiiaiou likeʻole, e like me kā lākou maʻiʻo ma ka pakeneka hua'ōlelo i hōʻike mai i loko o ka lepili. Ka huapalapala mua P keia o ia hoʻi, i ke kila mea he kiʻekiʻe wikiwiki, ka hope helu Hōʻike ka tungsten maʻiʻo ma ka pakeneka. Hou palapala Kû ke alo o nā alloying hehee wale, a me na helu e hele mai ana ma hope o ka palapala - kā lākou pakeneka kaumaha hapa iki i loko o ka oka a pau. Ke'ī mai, i ka palapala M Hōʻike i ke alo o ka molybdenum i loko o ka'ōnaehana, F - vanadium K - cobalt, A - naikokene.

E like me ka maʻiʻo o dopants māmā kila i ke hoʻolaha i tungsten, molybdenum, tungsten a me ka molybdenum. A kūikawā pūʻulu anao? Aou i eliiaʻi oka a me ka cobalt. Na oka a i ana ia i loko o ka hana ana i na mea paahana no ka machining māhele pilikia o superalloys. High mämä holo kila, oka a vanadium uaʻano nui manao no ka? Iecaianoaaiiie o na mea paahana, no laila,-kapaia "o ka hoopau ana" nā kūlanaʻelua - broaches, reamers a me ka 'ē aʻe.

Ka loa, he pono ole, a paha ua hoʻohana 'ia ka kahiko hao o ke kiʻekiʻe-ka māmā holo kila P18 no ka hana o ka luna' hoʻokino a me ka threading mea paahana. 'O ia hoʻi ka maʻamau ano no kiʻekiʻe ma Hawaiʻi aaioee o ka metala i i ka hapanui o P9 momoku ahi oka a pau. Mai ia hana o nā mea wili, kālai, a me ka e like.

Ma ka hana ana wela? Eia holo steels e māheleʻia i loko o ekolu waeʻano: oka a me ka maʻamau, kiʻekiʻe, a me nā kiʻekiʻe ka wela e kū'ē'ē mai. I ka pūʻulu mua no tungsten (R18, R9) a me ka tungsten-molybdenum (R6M5). e hoʻohana 'ia kēia mau kaha ma ka aaioee o ole-ferrous ke hooheheeia, mall steels a hoolei hao.

No ka mea o ka lua o ka waeʻano ua wehewehe aku ma ka maʻiʻo kiʻekiʻe loa o ka cobalt, vanadium a me ka kalapona. Ka loa hanohano momoku ahi i loko o ka pūʻulu - R6M5F3. Vanadium kila wehewehe aku ma ka kiʻekiʻe Wear e kū'ē'ē mai. Lākou nui wale drawback - ino sanding, no ka mea, o ka paakiki o ka vanadium carbides mea i emi iki mahope o ke ano like anakahi elektrokorundovogo wili huila.

Eia hoi, i ke kolu o ka waeʻano o ke kila wehewehe aku ma ka haahaa pakeneka o ka kalapona maʻiʻo, e ia e pono no ka hana maikaʻiʻole o ka wela-hoʻopale, kuhiliʻole kila a me ka titanium oka a pau. Kekahi ano hiʻona o ia - he nui helu o ka alloying hehee wale. I keia pae nā na ahi like 3V20K20H4F, V11M7K23 listen'ōlelo.
