Ibisobanuro birambuye

Imbaraga nyinshi zizimya zizatanga imbibi iyo zisubijwe. Bakeneye kwitabwaho bidasanzwe.

Hydrogen yataye ubusanzwe irangwa no gutinda gucika intege. Habayeho amasoko y'imodoka, yamenetse, imigozi, urupapuro rwamasoko n'ibindi bice byagiye bisimburana, mu gihe gito nyuma yo guterana kwaravunitse, kuvunika 40% ~ 50%. Muburyo bwo gukoresha ibice bya cadmium byibicuruzwa byihariye, hashyizweho ikibazo cyigihugu cyigihugu cyakemutse kandi inzira ikomeye yo kurwara dehyrognation yateguwe. Byongeye kandi, hari induru ya hydrogen igaragambya ntabwo igaragaza gutinda guhagarika ibintu, nka: Amashanyarazi, insinga, gutoranya, itontoma yinjira, akenshi igaragara mukoresha ububiko bibaho ibintu byomeneka; Mandrel y'imbunda, nyuma y'inshuro nyinshi za chroming, yikubita hasi iravunika; Ibice bimwe byazimye (imihangayiko nini yimbere) izacika iyo gutora. Ibi bice bifite hydrogenanted no gucamo imihangayiko yo hanze, bitagikoreshwa kugirango ugarure uburwayi bwumwimerere nuwamwutwa.

Imbaraga zumubiri, niko hydrogan itarambiwe nubwenge. Iki nikibazo cyibanze kigomba gusobanurwa nabatekinisiye bavurwa hejuru mugihe bakusanya ibikoresho bya electroplaties. Icyuma gifite imbaraga za tensile σb> 105Kg / MM2 isabwaga n'amahame mpuzamahanga agomba gukorerwa ibibazo mbere no gufatanya imbonankubone. Inganda z'indege z'Abafaransa zisaba kuvura imyagahisha ku buvuzi ku bice by'icyuma hamwe n'imbaraga zitanga σs> 90kg / mm2.

Kubera inzandiko nziza hagati yimbaraga zishushanyije no gukomera, biragoye kandi byoroshye gucira urubanza hydrogan itara zidasanzwe zibikoresho biteye ubukana kuruta imbaraga. Kuberako igipimo cyuzuye cyibicuruzwa hamwe nuburyo bwo gutanga bugomba gushyirwaho no gukomera kwicyuma. Muri electraplating, twasanze gukomera kwa ibyuma hirya no hino bya HRC38 byatangiye kwerekana ibyago byo kuvunika hydrogten. Kubice birenze HRC43, umwuma adashobora gusuzumwa nyuma yo kwipimisha. Iyo gukomera biri kuri HRC60, kuvura umwuma bigomba gukorerwa ako kanya nyuma yo kuvura hejuru, bitabaye ibyo ibice by'icyuma bizacika mu masaha make.
