ʻAʻole pili ka hoʻonā ʻana o ka ʻoihana cobalt kumu hoʻomaʻemaʻe kiʻekiʻe e pili ana i ke kūʻai ʻana i nā pahu hao a me ka holo ʻana ma o ka lathe.

Ua hana mākou i nā ʻāpana AMS 5387 no nā manifolds pauma hydraulic waho kahi i loaʻa ai kahi microcrack i ka wahi i hoʻopilikia ʻia i ka wela he $240,000 i ka wā hoʻomaha. ʻO ia ke kumu ʻaʻole he huaʻōlelo ʻimi wale ʻo "cobalt base factory" - he paepae ia. E ʻaʻa iā ia me ka ʻole o ka hoʻopaʻi metallurgical, ka ʻike ʻana i ke kaʻina hana, a i ʻole ka hiki ke hoʻoheheʻe ʻia-machining, a e ʻike ʻoe i nā helu ʻōpala ma luna o 37%, hoʻopaneʻe ʻia nā hōʻailona PPAP, a i ʻole nā hana hāʻule ma lalo o ka hoʻouka wela cyclic.
Hoʻomaka ka hana ʻana o ka ʻoihana cobalt base me ka pono o ka waiwai - ʻaʻole wale nā palapala hōʻoia. ʻO nā superalloys Cobalt-nickel e like me T800 a me AMS 5387 e koi ikaika i ka hoʻohele ʻana i ka nui o ka palaoa, morphology carbide, a me ka hoʻokaʻawale interdendritic. Ua ʻike mākou i nā mea kūʻai aku e hōʻole i nā wela holoʻokoʻa no ka mea i hōʻike ʻia nā hōʻike hoʻāʻo mill mea kūʻai aku "hui pū me AMS 5387” akā ua haʻalele ʻia ka hoʻonā hoʻoheheʻe ʻana i ka manawa soak a me ka helu hoʻomaha.

Akā ʻaʻole hiki ke hoʻokele waiwai wale nō me ka ʻole o ka hoʻolālā hana hoʻohui.
