ʻO ke kaʻina hana o ka pā Titanium

ʻO ka hoʻoheheʻe wela kahi hana forging i hana ʻia ma luna o ka metala recrystallization wela.
ʻO ka ʻōwili wela kahi hana ʻōwili i hana ʻia ma luna o ka mahana recrystallization.
ʻO ka ʻōwili anu he kaʻina olokaʻa kahi i haʻahaʻa ai ka mahana deformation plastic ma mua o ka mahana hoʻihoʻi.
Annealing: He kaʻina hana lapaʻau metala kahi e wela mālie ai ka metala i kekahi mahana, mālama ʻia no ka manawa kūpono, a laila hoʻomāaʻalili i ka wikiwiki kūpono (maʻa mau ka hoʻomaha mālie, i kekahi manawa mālama ʻia ka hoʻolili ʻana).
Pickling: Hoʻokomo ʻana i ka mea hana i loko o kahi hopena wai o ka sulfuric acid e wehe i nā oxides a me nā kiʻiʻoniʻoni ʻē aʻe ma ka ʻili metala. He lapaʻau mua ia a i ʻole lapaʻau waena no nā kaʻina hana e like me ka electroplating, enameling, a me ka ʻōwili.
