Njira yosiyanitsira zokutira kwa electrogalvanizing ndi kutentha kwa galvanizing

Zomangamanga zimakhala zamagulu ambiri, omwe nthawi zambiri amatchedwa "gawo lokhazikika".Kwa zomangira zina zolimba kwambiri komanso zolondola, chithandizo chapamwamba ndi chofunikira kwambiri kuposa chithandizo chamafuta.Mitundu yonse ya fasteners ntchito chiwerengero chachikulu cha zida makina, pafupifupi onse ayenera anasonkhana pambuyo mankhwala pamwamba, kuti tikwaniritse anticorrosion, zokongoletsera, kuvala kukana, kuchepetsa mikangano coefficient ndi zotsatira zina, ndi zolengedwa padziko mankhwala electrogalvanizing ndi kutentha galvanizing ndi. tekinoloje yotchinga chitetezo cha cathodic.

Mfundo electrogalvanizing zitsulo chomangira mankhwala ndi ntchito electrolysis, mapangidwe yunifolomu, wandiweyani, bwino ophatikizana zitsulo kapena aloyi mafunsidwe wosanjikiza pamwamba pa workpiece, mapangidwe wosanjikiza ❖ kuyanika pamwamba zitsulo pamwamba, kuti kupeza chitetezo cha njira dzimbiri zitsulo.Chifukwa chake, zokutira zama electrogalvanized ndikusuntha kolunjika kuchokera ku electrode yabwino kupita ku electrode yoyipa pogwiritsa ntchito pano.Zn2 + mu electrolyte ndi nucleated, kukula ndi kuikidwa pa gawo lapansi pansi pa mphamvu yokhoza kupanga galvanized layer.Munjira iyi, palibe njira yolumikizirana pakati pa zinki ndi chitsulo.Poyang'ana pa microscopic, iyenera kukhala yosanjikiza ya zinki.Kwenikweni, kutentha kuviika kanasonkhezereka chitsulo-zinki aloyi wosanjikiza ndi koyera nthaka wosanjikiza, ndipo kanasonkhezereka yekha wosanjikiza koyera nthaka wosanjikiza, kotero, ndi chitsulo-zinki aloyi wosanjikiza kwa ❖ kuyanika makamaka zochokera chizindikiritso cha ❖ kuyanika njira, oyenera zomangira kanasonkhezereka, waya zitsulo, chitoliro zitsulo ndi mankhwala ena.Njira ya Metallographic ndi njira ya XRD imagwiritsidwa ntchito kuzindikira zokutira kusiyanitsa electrogalvanizing ndi kutentha galvanizing, ndi kupereka chitsogozo pa kulephera kusanthula.

Pali njira ziwiri zodziwira zokutira za electrogalvanizing ndi kutentha kwa galvanizing.Imodzi ndi njira metallographic: njira metallographic si malire okhutira osiyanasiyana ndi kukula chitsanzo, ndi oyenera mankhwala onse electrogalvanizing ndi otentha galvanizing.Wina ndi njira ya X-ray diffraction: yogwiritsidwa ntchito ndi mainchesi oposa 5mm plating bolts ndi mtedza mu ndege ya hexagonal;The awiri akunja ndi wamkulu kuposa 8mm zitsulo chitoliro padziko mankhwala radian, kuonetsetsa kuti chitsanzo akhoza kukhala kukula osachepera 5mm × 5mm pamwamba chitsanzo lathyathyathya, ndi mitundu yonse ya mankhwala ❖ kuyanika.Itha kutsimikizira mawonekedwe a kristalo azinthu zokutira ≥5% gawo.Zitsanzo zokhala ndi ma depositi a zinki okhuthala kwambiri sizoyenera kwa X -ray diffraction.
