Kuvura ubushyuhe bwihuse, usibye kugenzura no kugenzura ubuziranenge muri rusange, hari ubugenzuzi bwihariye bwihariye no kugenzura, ubu tuvuze kuvura ubushyuhe ahantu henshi hagenzurwa
01 Decarburisation na carburisation
Kugirango umenye mugihe cyo kugenzura itanura rya karubone, urashobora gukoresha spark detection hamwe na test ya Hardwell igerageza kugirango decarburisation na carburisation kugirango uburanishwe mbere.
Ikizamini.
Ese ibice byazimye, muri gride kuva hejuru no imbere gusya buhoro buhoro urumuri rwimanza kandi umutima wubwinshi bwa karubone urahoraho.Ariko ibi birasaba uyikoresha kugira tekinike nubuhanga kugirango amenye ubushobozi.
Ikizamini gikomeye.
Bikorewe kuruhande rwa mpande esheshatu.Ubwa mbere ibice byakomereje byindege ya mpandeshatu hamwe na sandpaper byoroheje, bipima ubukana bwa mbere bwa Rockwell.Noneho ubu buso muri sander kugirango busya hafi 0.5mm, hanyuma upime ubukana bwa Rockwell.
Niba ubukana bwagaciro bwibihe byombi aribwo bumwe, ibyo ntabwo ari decarburisation, cyangwa carburisation.
Iyo ubukana bwambere buri munsi yubukomezi bwa nyuma, bivuze ko ubuso bwa decarburize.
Ubukomere bwambere burenze ubukana bwa nyuma, ko hejuru ya karburizasi.
Muri rusange, itandukaniro ryibintu bibiri bitandukanya 5HRC cyangwa munsi yayo, hamwe nuburyo bwa metallografiya cyangwa uburyo bwa microhardness, ibice bya decarburisation cyangwa carburisation ahanini biri mubisabwa.
02 Gukomera n'imbaraga
Mubigeragezo byihuta byikizamini, ntibishobora gushingira gusa kuburemere bwigiciro cyigitabo gikwiye, gihinduwe agaciro.Hariho ikintu gikomeye cyo gukomera hagati.
Muri rusange, gukomera kw'ibikoresho ni byiza, ubukana bw'igice cyambukiranya igice cya screw gishobora kugabanywa kimwe, igihe cyose gukomera byujuje ibisabwa, imbaraga no kwemeza ko imihangayiko nayo ishobora kuzuza ibisabwa;
Iyo gukomera kw'ibikoresho ari bibi, nubwo ukurikije igice cyagenwe cya sheki, ubukana bujuje ibisabwa, ariko imbaraga n'ingwate byemeza akenshi ntabwo byujuje ibisabwa.Cyane cyane iyo ubukana bwubuso bugana kumupaka wo hasi, kugirango ugenzure imbaraga kandi wizere ko uhangayikishijwe nurwego rwujuje ibyangombwa, akenshi uzamura agaciro kari munsi yuburemere.
03Gusubiramo ikizamini
Ikizamini cyo gusubiramo gishobora kugenzura kuzimya ubukana ntibihagije, hamwe nubushyuhe bwo hasi cyane kugirango bugere ku rugero rukomeye rwimikorere idakwiye, kugirango harebwe niba imiterere yimikorere yibice.
Cyane cyane karubone ya martensitike ikora ibyuma bifata imigozi, ubushyuhe buke, nubwo ubundi buryo bwubukanishi bushobora kuzuza ibisabwa, ariko gupima impungenge zemewe, ihindagurika ryigihe kirekire risigaye ni rinini cyane, rirenze kure 12.5um, kandi mubihe bimwe na bimwe byo gukoresha bizaba bitunguranye kuvunika, mumamodoka amwe n'amwe yo kubaka bolts, byagaragaye mubintu byo kuvunika gutunguranye.
Mugihe ubushyuhe bwo hasi bwubushyuhe bukabije, burashobora kugabanya ibintu byavuzwe haruguru, ariko hamwe na karubone nkeya ya martensitike ikora ibyuma 10.9 byo mu cyiciro, bigomba kwitonda cyane.
04 Kugenzura kwinjiza hydrogène
Kworoherwa no kwinjiza hydrogène byiyongera hamwe nimbaraga zo kwihuta.Gufunga imigozi yo hanze yo mu cyiciro cya 10.9 no hejuru yayo, hejuru yikomye hejuru yo kwikubita hasi, imigozi yo guhuza hamwe no gukaraba ibyuma, nibindi bigomba kuba umwuma nyuma yo kubisiga.
Ubuvuzi bwa Dehydrogenation mubusanzwe buri mu ziko cyangwa itanura, bifata kuri 190 ~ 230℃kurenza 4h, kugirango hydrogène ikwirakwizwa.
"Icyuma kiracyakeneye ubukana bwacyo!"Nubwo uko isoko ryahinduka gute, gutunganya inzira yinganda nabyo ni bumwe muburyo bwiza bwo kurwanya ingaruka.
Muburyo bwo kuvura ubushyuhe bwihuse, nta gushidikanya ko ari ngombwa cyane gukora akazi keza mu ngingo zingenzi zigenzura, nacyo kikaba ari kimwe mubintu buri kigo cyiza cyo gutunganya ubushyuhe bwihuse gikwiye gukora neza.
