Aluminum Alloy Surface Treatment: 7 Series Aluminum Hard Anodizing

1. Nānā Kaʻina Hana

Hoʻohana ka anodizing paʻakikī i ka electrolyte pili o ka mea hoʻoheheʻe (e like me ka sulfuric acid, chromic acid, oxalic acid, etc.) e like me ka anode, a hana i ka electrolysis ma lalo o kekahi mau kūlana a hoʻohana i kēia manawa. ʻO 25-150um ka mānoanoa o ke kiʻi anodized paʻakikī. ʻO nā kiʻiʻoniʻoni anodized paʻakikī me ka mānoanoa kiʻiʻoniʻoni ma lalo o 25um e hoʻohana nui ʻia no nā ʻāpana e like me nā kī niho a me nā spirals. Pono ka mānoanoa o nā kiʻi ʻoniʻoni anodized paʻakikī e 50-80um. ʻO ka lole pale a i ʻole ka mānoanoa o ke kiʻi anodized no ka insulation ma kahi o 50um. Ma lalo o kekahi mau kūlana kaʻina hana kūikawā, pono ia e hana i nā kiʻiʻoniʻoni anodized paʻakikī me ka mānoanoa o ka 125um. Eia naʻe, pono e hoʻomaopopo ʻia ʻoi aku ka mānoanoa o ke kiʻiʻoniʻoni anodized, ʻoi aku ka haʻahaʻa o ka microhardness o kona papa waho, a e piʻi aʻe ka roughness ʻili o ka papa kiʻiʻoniʻoni.

2. Kaʻina hana

1) ʻO ka paʻakikī o ka alumini alumini ma hope o ka anodizing paʻakikī hiki ke piʻi i kahi HV500;

2) Anodic oxide film mānoanoa: 25-150 microns;

3) Hoʻopili ikaika, e like me nā ʻano anodizing i hana ʻia e ka anodizing paʻakikī: 50% o ke kiʻi anodizing i hana ʻia e komo i loko o ka alumini alumini, a ʻo 50% pili i ka ʻili o ka alumini alumini (ka ulu ʻana o ka bidirectional);

4) Hoʻopili maikaʻi: hiki ke hōʻea i ka voltage breakdown i 2000V;

5) Paipai maikaʻi ʻaʻahu: No nā alumini alumini me kahi ʻāpana keleawe ma lalo o 2%, ʻo 3.5mg / 1000 rpm ka helu ʻoi loa. ʻAʻole pono e ʻoi aku ka nui o ka helu ʻana o nā huila ʻē aʻe ma mua o 1.5mg/1000 rpm.

6) ʻAʻohe mea ʻawaʻawa a pōʻino i ke kino kanaka. ʻO ke kaʻina hana electrochemical o ka anodizing kiʻiʻoniʻoni i hoʻohana ʻia no ka hana ʻana he mea ʻino ʻole, no laila, no ka pono o ka mālama ʻana i ke kaiapuni i ka nui o ka mīkini ʻenehana ʻoihana, hoʻohana kekahi mau huahana i ke alumini anodized paʻakikī ma kahi o ke kila kila, ka pulupulu kuʻuna, ka chromium plating a me nā kaʻina hana ʻē aʻe.

3. Nā kahua noi

He kūpono ka anodizing paʻakikī no nā wahi e koi ana i ke kūpaʻa lole kiʻekiʻe, ka pale wela, a me nā waiwai insulation maikaʻi o nā ʻāpana alumini a me nā alumini. E like me nā cylinders like ʻole, pistons, valves, cylinder liners, bearings, aircraft cargo compartments, tilt rods and guide rails, hydraulic equipment, steam impellers, comfort flatbed machines, gears and buffers, etc. ke kumu kūʻai, akā ʻo ka hemahema o kēia kiʻiʻoniʻoni ʻo ia ka nui o ka mānoanoa o ke kiʻiʻoniʻoni, pili ia i ka hoʻomanawanui o ka ikaika luhi mechanical o nā alumini a me nā alumini alumini.
