1. Kaiapuni kumu o ka corrosion
Latitu a me ka longitude, ka wela, ka haʻahaʻa, ka pāhawewe holoʻokoʻa (ka ikaika o ka uv, ka lōʻihi o ka lā), ka ua, ka waiwai pH, ka wikiwiki o ka makani, ke kuhikuhi makani, ka sediment corrosive (C1, SO2).
2. Ka hopena o ka lā
ʻO ka lā ka nalu electromagnetic, e like me ka ikehu a me ke alapine o ka pae i māhele ʻia i nā kukuna gamma, nā kukui X, ultraviolet, ʻike ʻia ke kukui, infrared, microwave a me nā hawewe lekiō.Aia ka ULTRAVIOLET spectrum (UV) i ka radiation frequency kiʻekiʻe, i ʻoi aku ka luku ma mua o ka spectrum ikehu haʻahaʻa.No ka laʻana, ʻike mākou ʻo nā wahi ʻeleʻele o ka ʻili a me ka maʻi kanesa ʻili ke kumu o nā kukuna ultraviolet o ka lā.Hiki nō hoʻi iā UV ke uhaki i nā mea paʻa kemika o kahi mea, e uhaʻi ai, ma muli o ka lōʻihi nalu o UV a me ka ikaika o nā mea paʻa kemika o ka mea.He hopena koʻikoʻi ka X-ray, a hiki i nā kukuna gamma ke uhaki i nā mea paʻa kemika a hoʻohua i nā ion i hoʻokuʻu ʻole ʻia, he mea make i nā mea ola.
3. Ka hopena o ka mahana a me ka haʻahaʻa
No ka uhi metala, ʻo ka wela kiʻekiʻe a me ka haʻahaʻa e kōkua i ka hopena oxidation (corrosion).ʻO ke ʻano molekala o ka pena ma ka ʻili o ka papa uhi waihoʻoluʻu e maʻalahi ke hoʻopōʻino i ka wā lōʻihi.Ke kiʻekiʻe ka haʻahaʻa, maʻalahi ka ʻili i ka condensation a hoʻonui ʻia ke ʻano corrosion electrochemical.
4. Ka hopena o ka ph i ka hana ʻino
No nā waihona metala (zinc a i ʻole alumini) he mau metala amphoteric lākou a hiki ke ʻino ʻia e nā ʻakika ikaika a me nā kumu.Akā ʻokoʻa ka ʻakika metala a me ka hiki ke kūpaʻa alkali i kona mau hiʻohiʻona ponoʻī, ʻoi aku ka ikaika o ke kūpaʻa alkaline galvanized plate, ʻoi aku ka ikaika o ke kūpaʻa zinc acid alumini.
5. Ka hopena o ka ua
ʻO ke kūpaʻa ʻana o ka wai ua i ka papa pena e pili ana i ke ʻano o ka hale a me ka ʻakika o ka wai ua.No nā hale me kahi piʻi nui (e like me nā paia), he hana hoʻomaʻemaʻe ka wai ua e pale ai i ka ʻino hou ʻana, akā inā hoʻoheheʻe ʻia nā ʻāpana me kahi pali liʻiliʻi (e like me ka uhi ʻana), e waiho ka wai ua ma luna o ka ʻili no kahi. manawa lōʻihi, e paipai ana i ka uhi ʻana i ka hydrolysis a me ke komo ʻana o ka wai.No nā ʻāpana a i ʻole nā ʻoki o nā papa kila, ʻo ka hiki ʻana o ka wai e hoʻonui i ka hiki ke hoʻoheheʻe electrochemical, he mea nui hoʻi ka orientation, a ʻoi aku ka koʻikoʻi o ka ua waikawa.
