ʻO ka hoʻomaʻamaʻa ʻana i ka wela he ana kūpono loa e hoʻomaikaʻi a hoʻololi i nā waiwai o 15CrMo alloy round steel. He kuleana koʻikoʻi ia i ka hilinaʻi huahana a me ka hoʻokele waiwai. ʻO ka hoʻomaʻamaʻa wela o ka 15CrMo alloy round steel ka mea maʻamau e pili ana i ka mālama wela maʻamau (annealing, normalizing, quenching, tempering) a me ka mālama wela o ka ʻili (ka hoʻopau ʻana i ka ʻili a me ka mālama wela kemika-carburizing, nitriding, metalizing, etc.).
I ka ʻenekinia mechanical, he nui nā ʻāpana mīkini, e like me nā crankshafts, gears, camshafts o nā ʻenekini hoʻopau i loko, a me nā mīkini i nā mea hoʻohaʻahaʻa koʻikoʻi, ʻaʻole pono wale ka paʻakikī, ka plasticity a me ka ikaika kulou i loko o ke kumu, akā pono pū kekahi i ka mānoanoa kiʻekiʻe i loko o kekahi mānoanoa. . ʻO ka paʻakikī, ke kūpaʻa ʻaʻahu kiʻekiʻe a me ka ikaika luhi kiʻekiʻe. ʻO nā ʻano hana lapaʻau holoʻokoʻa holoʻokoʻa i ʻōlelo ʻia ma luna nei he paʻakikī ke hoʻokō i nā koi o ka hana ma luna i ka manawa like, a ʻo ka hoʻohana ʻana i ka hoʻomaʻamaʻa ʻana i ka wela o ka honua ke ala kūpono loa e hoʻokō ai i kēia mau koi hana i ka manawa like.
ʻO ka hoʻomaʻamaʻa ʻana i ka wela o ka ʻili he ʻano hana wela e hoʻololi i nā waiwai o ka ili o 15CrMo alloy poepoe kila ma ka hoʻololi ʻana i ke ʻano o ka papa honua.
ʻO ka hoʻopau ʻana i ka ʻili he hana wela e hoʻololi i ke ʻano o ka ʻili i kēlā me kēia me ka ʻole o ka hoʻololi ʻana i ke ʻano kemika o ka ʻili. Hiki ke hoʻomaopopo ʻia e ke alapine kiʻekiʻe, medium frequency a i ʻole ke ala hoʻomehana induction i kēia manawa a i ʻole ke ʻano wela wela. ʻO ka hiʻohiʻona maʻamau, ʻo ka ili o ka 15CrMo alloy poepoe kila e wela koke i ka wela kinai, a i ka wā ʻaʻole e hoʻoneʻe ʻia ka wela i ke kumu o ka ʻāpana, ua maʻalili koke ia, i kiʻekiʻe ka paʻakikī o ka ʻili, akā ʻo ka paʻakikī kiʻekiʻe nō ka core.
ʻO ka lāʻau lapaʻau ke ʻano hana wela e hoʻololi i ka haku mele a me ke ʻano o ka papa honua o 15CrMo alloy round steel. Hiki ke hoʻokaʻawale ʻia ka mālama wela kemika i nā ʻano e like me ka carburizing, nitriding, carbonitriding, a me ka metalizing e like me nā mea like ʻole i hoʻokomo ʻia ma ka ʻili o 15CrMo alloy round steel. He mea maikaʻi loa ia no ka hoʻomaikaʻi ʻana a me ka hoʻomaikaʻi ʻana i ke kūpaʻa ʻaʻahu, ka pale ʻana i ka corrosion a me ke kūpaʻa luhi o ka 15CrMo alloy round steel. I kēia manawa, ua ulu wikiwiki ka mālama ʻana i ka wela kemika, a ua nui nā noi o nā ʻenehana hou.
