1. He aha ka lae palupalu kinai
ʻO ka mea i kapa ʻia ʻo quenching soft point, ʻo ia ka wahi palupalu paʻa ʻole ma nā ʻāpana. e hoʻolohi i ka wikiwiki hoʻoluʻu. Ua ʻike pinepine ʻia kēia ʻano ʻo ka Leiden hau hau. ua like me ke kinai ana i kahi palupalu.
Ua olelo ia i loko o ka plum ua kau mea prone i quenching palupalu wahi, ina ka humidity o ka quenching kahua oi ma mua o 55%, ia mea prone i quenching wahi palupalu.
ʻO ka ʻili o nā ʻāpana hoʻopiʻi kiʻekiʻe e pili ana i ka barber scar, a i ʻole ka ʻaoʻao o ka pahi Kepani, ʻo nā waihoʻoluʻu ʻālohilohi e kinai ana i kahi palupalu.
2. Pehea e ʻike ai i ka wahi palupalu kinai
ʻEkolu mau ala maʻamau e ʻike ai i nā wahi palupalu i kinai ʻia. ʻO ke ʻano mua e ʻike i ka waihoʻoluʻu ʻulaʻula māmā ma ka ʻili wili: ʻo ke ala ʻelua ʻo ke ala ʻekolu ʻo ka hoʻohana ʻana i ka corrosion acid e ʻike ai i ka wahi palupalu kinai;ʻo ia hoʻi, e hoʻopaʻa i nā ʻāpana i loko o 50% hydrochloric acid wai solution (wai wai) no ka corrosion, inā ʻike ʻia ka ʻāpana ʻeleʻele i kahi wahi ʻeleʻele, ʻo ka ʻāpana ʻeleʻele ka mea ʻeleʻele kinai. ~ 200C) nā ʻāpana i corroded i loko o ka paakiki wahi, a me ka waihoʻoluʻu i ka unhardened wahi.ʻO ka hohonu o ka quenched papa hiki ke ana me keia ano.
3. Pehea e pale ai i ke kinai ʻana mai ka wahi palupalu
No ka paleʻana i ka hoʻopauʻana i nā wahi palupalu, mai hoʻonāukiʻole a decarbonize paha i nā'āpana i ka wā e hoʻomehana mua ai. ʻoluʻolu. Eia kekahi, inā hiki i ka hoʻopiʻi ʻana me 10% wai paʻakai ke pale loa i ka hoʻopau ʻana o nā wahi palupalu. ʻOi aku ka maʻalili o ka pauka polishing ma mua o nā ʻāpana kila i uhi ʻole ʻia a ʻaʻole e kinai i ka wahi palupalu, no laila ʻo ka hoʻohana ʻana i ka pauka polishing i ka hana hoʻopau ʻana i ka pahi Kepani he ala huna. Akā pono e lawe ʻia.Inā mānoanoa loa ka pauda polishing, lohi ka hoʻolili ʻana, ʻaʻole paʻakikī.
He lahilahi ka pauda polishing a hoʻopili ʻia i ka ʻili o nā ʻāpana kinai, a i ka wā e hoʻopiʻi ʻia ai, ʻaʻole i hoʻopuni ʻia ka ʻili e ka kiʻiʻoniʻoni mahu, a lilo ia i mau puʻupuʻu liʻiliʻi a piʻi ikaika, no laila e maʻalili wikiwiki.
Ma ke ʻano he mea ʻaʻahu, ma waho aʻe o ka pauka polishing.A me ka lehu me kaolin a me ka wai;mika me ka lepo palupalu a me ka wai: pumice me ka palolo palupalu a me ka wai, ua olelo ia he mau mea maikai.
I kēia mau lā, hoʻohana nui ʻia ka wai-soluble quenching solution (polymer quenching solution) ma kahi o ka ʻaila kinai, nona ka solubility inverse a hiki ke hana i kahi kiʻiʻoniʻoni ma ka ʻili ke hoʻomehana ʻia e nā ʻāpana i mālama ʻia.Ke hāʻule ka mahana ma kahi o 90 ℃ (kekahi mau hoʻonā he 74 ℃), ua hoʻoheheʻe ʻia ka pale maka. ka hoʻohana ʻana i ka pauka polū me ia}
Eia kekahi, inā hiki ke hoʻoneʻe maikaʻi ʻia ke kani ultrasonic "25000 wiki / s), no laila hiki ke pale ʻia ke kinai ʻana o nā wahi palupalu.
