ʻO ka ʻokoʻa ma waena o nā microscope metallographic kū pololei a me nā microscope metallographic i hoʻohuli ʻia

1. I kēia lā e nānā kākou i ka ʻokoʻa ma waena o nā microscope metallographic kū pololei a me nā microscope metallographic i hoʻohuli ʻia: ʻO ke kumu i kapa ʻia ai ka microscope metallographic i hoʻohuli ʻia he inverted, ʻo ia ka mea aia ka lens objective ma lalo o ke kahua, a pono e hoʻohuli ʻia ka workpiece i lalo ma ke kahua no ka nānā ʻana a me ka nānā ʻana. Ua lako wale ʻia me kahi ʻōnaehana kukui i hoʻohuli ʻia, ʻoi aku ka kūpono no ka nānā ʻana i nā mea metala.

Aia ka microscope metallographic kū pololei i ka lens objective ma ke kahua a ua kau ʻia ka workpiece ma ke kahua, no laila ua kapa ʻia ʻo ia he kū pololei. Hiki ke hoʻolako ʻia me kahi ʻōnaehana kukui i hoʻouna ʻia a me kahi ʻōnaehana kukui i hoʻohuli ʻia, ʻo ia hoʻi, ʻelua mau kumu kukui ma luna a ma lalo, hiki ke nānā i nā plastics, rubber, nā papa kaapuni, nā kiʻiʻoniʻoni, nā semiconductors, nā metala a me nā mea ʻē aʻe.

No laila, i ke kahua mua o ka nānā ʻana i ka metallographic, ʻo ke kaʻina hana hoʻomākaukau laʻana i hoʻohuli ʻia e pono ai ke hana i hoʻokahi ʻili wale nō, ʻoi aku ka maʻalahi ma mua o ka mea kū pololei. Makemake ka hapa nui o ka mālama wela, ka hoʻolei ʻana, nā huahana metala a me nā hale hana mīkini i nā microscope metallographic i hoʻohuli ʻia, ʻoiai makemake nā ʻāpana noiʻi ʻepekema i nā microscope metallographic kū pololei.

2. Nā akahele no ka hoʻohana ʻana i kahi microscope metallographic:

1) Pono mākou e hoʻolohe i kēia mau mea i ka wā e hoʻohana ai i kēia microscope metallographic pae noiʻi:

2) E hōʻalo i ke kau ʻana i ka microscope ma nā wahi me ka lā pololei, ka mahana kiʻekiʻe a i ʻole ka haʻahaʻa kiʻekiʻe, ka lepo, a me nā haʻalulu ikaika, a e hōʻoia i ka pālahalaha a me ka pae o ka ʻili hana.

3) Pono ʻelua kānaka e hoʻoneʻe i ka microscope, paʻa kekahi kanaka i ka lima me nā lima ʻelua, a paʻa kekahi kanaka i ka lalo o ke kino o ka microscope a kau pono iā ia

4) I ka wā e hoʻoneʻe ai i ka microscope, mai paʻa i ke kahua microscope, ka pihi hoʻopololei, ka ʻōmole nānā, a me ke kumu kukui e pale aku i ka hōʻino ʻana i ka microscope

5) E wela loa ka ʻili o ke kumu kukui, a pono ʻoe e hōʻoia i ka lawa ʻana o ka wahi hoʻopuehu wela a puni ke kumu kukui.

6) No ka hōʻoia ʻana i ka palekana, e hōʻoia i ka "O" ke kuapo nui ma mua o ke kau ʻana i ke kukui a i ʻole ka fuse
