DIN912 Hex Socket Igikombe Umutwe M3-M30 / Umuringa Igice / Umutwe wuzuye

Imbaraga zikomeye zifatika zizatanga crispness mugihe zishizwemo.Ukeneye kwitabwaho bidasanzwe.

Kwinjiza hydrogène mubisanzwe birangwa no gutinda kuvunika mukibazo.Habayeho amasoko yimodoka, koza, imashini, amasoko yamashanyarazi nibindi bice bya galvanis, mumasaha make nyuma yinteko imaze gucika, igipimo cyo kuvunika cya 40% ~ 50%.Muri gahunda yo gukoresha ibice byometse kuri kadmium yibicuruzwa bidasanzwe, habaye kuvunika ibice, kandi ikibazo cyingenzi cyigihugu cyakemutse kandi hashyirwaho uburyo bukomeye bwo kubura umwuma.Byongeye kandi, hari hydrogène yinjizwamo ntabwo yerekana ibintu byatinze kuvunika, nka: amashanyarazi ya elegitoronike (insinga z'icyuma, insinga z'umuringa) bitewe ninshuro nyinshi zo gufata amashanyarazi no gutoragura, hydrogene yinjira birakomeye, akenshi bigaragara mugukoresha inshuro bibaho kuvunika kuvunika;Mandel yimbunda, nyuma yinshuro nyinshi za chroming, yaguye hasi iravunika;Ibice bimwe byazimye (stress nini y'imbere) bizacika mugihe cyo gutoragura.Ibi bice ni hydrogène cyane kandi biravunika nta guhangayikishwa n’inyuma, bitagishobora gukoreshwa mu kugarura ubukana bwumwimerere hakoreshejwe dehydrogenation.

Iyo imbaraga zifatika zingana, niko hydrogène yinjira cyane.Iki nigitekerezo cyibanze kigomba gusobanurwa nabatekinisiye bavura hejuru mugihe bategura uburyo bwa electroplating process.Ibyuma bifite imbaraga zingana σb> 105kg / mm2 bisabwa nubuziranenge mpuzamahanga bigomba gukorerwa imihangayiko mbere yo kuvura no kuvura dehydrogenation nyuma yisahani.Inganda z’indege z’Abafaransa zisaba kuvura dehydrogenation ijyanye n’ibice byibyuma bifite imbaraga σs> 90kg / mm2.

Bitewe no kwandikirana kwiza hagati yingufu zicyuma nubukomere, biroroshye kandi byoroshye gucira urubanza hydrogène embrittlement sensibilité yibintu ukoresheje ubukana kuruta imbaraga.Kuberako ibicuruzwa byiza byo gushushanya no gutunganya bigomba kurangwa nicyuma gikomeye.Muri electroplating, twasanze ubukana bwibyuma hafi ya HRC38 bwatangiye kwerekana ibyago byo kuvunika hydrogène.Kubice birenze HRC43, dehydrogenation igomba gutekerezwa nyuma yo kuyisiga.Iyo ubukana buri hafi ya HRC60, kuvura dehydrogenation bigomba gukorwa ako kanya nyuma yo kuvurwa hejuru, bitabaye ibyo ibice byibyuma bikavunika mumasaha make.
