"Hoʻohālikelike hoʻohālikelike" ʻōnaehana metallographic: ʻo ke ʻano metallographic o ka poloka haumia metala he ferrite.

E hoʻoholo i ke kumu o ka hoʻopalekana metala haumia ma o ka hoʻohālikelike hoʻohālike.

"Hoʻohālikelike hoʻohālikelike" ʻōnaehana metallographic: ʻo ke ʻano metallographic o ka poloka haumia metala he ferrite.

ʻO ke ʻano metallographic o ka "mea hoʻohālikelike" penei:

A.ʻO ke ʻano metallographic o ke kino pauma o ka pauma kiʻekiʻeα paʻa paʻa + acicular eutectic silicon;

B. ʻO ka hana metallographic o ka plunger, ʻo kona ʻano metallographic he martensite + granular carbide;

C. ʻO ka hana metallographic o ka lima plunger, ʻo ka ʻili o ka metallographic ʻo martensite + paʻa austenite;

D. ʻO ke ʻano metallographic o ka pūpū injector, ʻo ia ka flaky pearlite + nui a me ka reticular ferrite.

E. Needle valve metallographic structure, kona metallographic structure is martensite + band

F. ʻO ke ʻano metallographic o ke kino valve needle, ʻo kona ʻano metallographic he martensite + granular carbide;

G. He ferrite ka hana metallographic o ka paipu kiʻekiʻe.

Ma o ka hoʻohālikelike i luna, ua kūlike ke ʻano metallographic o ka paipu aila kiʻekiʻe me ka mea o ka blockage haumia metala, ʻelua mau ferrite, e hōʻike ana i ka hemo ʻana o ka blockage mai ka paipu ʻaila kiʻekiʻe, a laila hoʻoholo i ka kumu o ka hoʻopaʻa ʻana i ka haumia metala. ʻO ka hope, manaʻo ʻia i ka wā e hoʻonohonoho ai i ka ʻōnaehana hoʻolako wahie diesel, pono e hoʻoikaika ʻia ka deburring a me ka hoʻomaʻemaʻe ʻana i nā paipu wahie kiʻekiʻe i hoʻohana ʻia, a ua loaʻa nā hopena maikaʻi.

Me ka hoʻomau mau ʻana o ka hoʻokele waiwai o ka mākeke a me ka hoʻoikaika ʻana o ka hoʻokūkū mākeke, pono e loaʻa i kahi huahana me ka hoʻokūkū ikaika nā hōʻailona hana maikaʻi loa ma ka hoʻohui ʻana i nā kumu kumu kūʻai, a ʻoi aku ka mea nui, pono e loaʻa nā hōʻailona hilinaʻi maikaʻi loa a me nā helu haʻahaʻa haʻahaʻa i ka hoʻohana ʻana. No laila, ʻo ka hoʻomaikaʻi ʻana i ka pae hilinaʻi o nā huahana ka pono o ka hoʻokūkū mākeke a me kekahi o nā mea e pono ai nā huahana e hoʻokūkū.
