He maikaʻi ka wili a me ka elongation, hiki ke pale i ke kaomi o ka hana mechanical, i ko mākou ʻāina ʻoihana i hana nui loa.Nui nā ʻano uea hao, ʻo ka mea maʻamau ka hāʻawi ʻana i ka uea hao ʻeleʻele,uwea hao hao.Hoʻomaikaʻi maikaʻi ʻia ka pale ʻana o ka corrosion o ka uhi waho, akā e ʻike ʻia ke ʻano o ka corrosion crevice ma hope o ka hoʻohana lōʻihi.
He ʻano ʻino ʻia ʻo Crevice corrosion ma kahi liʻiliʻi, ʻoi aku hoʻi ma kahi huna, hiki ke hana i ka pōʻai kino kino.Aneane hiki i ka crevice corrosion ke hana i loko o ka metala metala, me ke kinoea i loaʻa i ka anionic neutral medium Z he maʻalahi ke kumu i ka corrosion crevice, hiki pinepine ka corrosion crevice i ka aperture o 0.025 a 0.1 mm, no ka lōʻihi o ka hōʻiliʻili ʻana, mau nā māwae. he moʻo o nā haumia, hui pū ʻia me ke kaiapuni o waho o ka pulu maʻalahi e ʻino i ka wahi o ka ʻāpana liʻiliʻi.
ʻO ka loaʻa ʻana o ia mau mea haumia i ka wā lōʻihi e hopena i ka hoʻololi ʻana a me ka ʻinoʻino.ʻO ka hoʻonā pololei i kēia hanana ka hoʻoikaika ʻana i ka uhi ʻana o ka mea e pale ai i ka corrosion.E hoʻomaikaʻi i ka maikaʻi o ka uea hao galvanized, hiki ke hoʻohana i ka uea i hoʻopaʻa ʻia i ka zinc ma mua e huki ai i ka wā e hana ai i ka galvanizeduwea hao, ʻaʻole e ʻike ʻia ke ʻano o nā waiwai mechanical maikaʻi ʻole.He 15 a 25 pakeneka ka oi o ka oolea o ka uwea ma mua o ko ka uwea huki a me ka uwea hao, a ma kekahi mau mea i oi aku ka ikaika ma mua o ko ka uwea i poniia.
ʻO ka uea ma hope o ka plating mua, ʻoi aku ka kiʻekiʻe o kona palena ikaika ma mua o ka plating mua, plated zinc a laila hana ʻia me ka uea ʻaʻole wale ka paʻakikī a me ka ikaika kiʻekiʻe.Aia kahi helu haʻahaʻa i ka palena ikaika o ka uea hao galvanized no ka maikaʻi o ka zinc, no ka mea, ʻoi aku ka liʻiliʻi o ka ikaika o ka ʻenehana zinc ma mua o ka uea ponoʻī.He mea paʻakikī ke hoʻopaʻa wela i nā uea i huki ʻia, a ʻaʻole hiki ke uhi ʻia nā uea ʻoi aku ka maikaʻi me ka mānoanoa o ka zinc maʻemaʻe.
