Iinkonzo zokuLungiselela kunye nokuLungiselela iiPlati zokuNxiba eziPheleleyo

Kwimveliso yemizi-mveliso yanamhlanje, ipleyiti yokunxiba ye-CCO (ipleyiti engagugiyo ye-chromium carbide overlay() isetyenziswa kakhulu kwiindawo ezinxitywa kakhulu ezifana nemigodi, izixhobo zokwakha, intsimbi, kunye nombane ngenxa yokumelana kwayo nokuguguleka okugqwesileyo kunye nokuguquguquka kokucubungula okwahlukeneyo. Yenziwe nge-alloy ephezulu ye-chromium edityanisiweyo kumphezulu we-substrate yentsimbi ephantsi kwekhabhoni, yenza isakhiwo esidityanisiweyo esingagugiyo se-bimetallic esinobunzima obukhulu kunye nobunzima, esinokwandisa ubomi benkonzo yezixhobo kwaye sinciphise iindleko zokugcinwa. Eli nqaku liza kwazisa ukwakheka, iimpawu zokusebenza, kunye neenkonzo zokucubungula ezenzelwe wena zepleyiti yokuguguleka ye-CCO ukunceda abasebenzisi baqonde ngcono kwaye basebenzise le nto.

Ukwakhiwa kwepleyiti engagugiyo egqunywe yi-overlay

I-alloy ye-high-carbon ephezulu ye-chromium yeyona nto iphambili kwi-Ipleyiti yokunxiba ye-CCO. Icandelo layo eliphambili linokwenza inani elikhulu le-Cr7C3 hard carbide phantsi kobushushu obuphezulu kunye neemeko zoxinzelelo oluphezulu, okwenza isakhiwo se-eutectic + M7C3 microstructure. Esi sakhiwo simisela ukumelana nokuguguleka okugqwesileyo, okuhlala kuzinzile nakwiindawo ezinzima zokuguguleka. Ukuphucula ukusebenza ngokubanzi, izinto ezincinci ezifana ne-molybdenum, i-tungsten, i-vanadium, i-boron, kunye ne-niobium nazo zingongezwa kwizinto ukuze kuphuculwe ubunzima bobushushu obuphezulu, ukumelana nempembelelo, kunye nokumelana nokugqwala.

Iikhabhide ze-M7C3 zibekwe phantsi kwesakhiwo esincinci ngokwexesha elide. Esi sakhiwo sisenokugcina ukusebenza kakuhle phantsi kobushushu obuphezulu okanye iimeko zokungqubana okukhulu, zigqitha kakhulu intsimbi eqhelekileyo.

Ukusebenza okuphambili kwepleyiti engagugiyo egqunywe yi-overlay

Ukumelana neempembelelo yenye yezona ndlela zibalulekileyo zokugweba umgangatho weepleyiti ezingagugiyo. Umaleko wokubopha wesinyithi wepleyiti engagugiyo ye-CCO wenza umaleko wokugquma unamathele ngokuqinileyo kwi-substrate yepleyiti yentsimbi, kungabi lula ukuwa, kwaye uhlala uzinzile kwaye uthembekile nokuba uphantsi kwempembelelo enamandla okanye umthwalo omkhulu.

Iipleyiti ze-CCO zinokufikelela ekuhlukaniseni ngokuchanekileyo nge-laser, i-plasma, kwaye zinokucutshungulwa ngeendlela ezahlukeneyo, ezifana nokugoba okubandayo, ukubhola, ukuwelda, njl.njl., ngaphandle kokunciphisa kakhulu ukumelana kwazo nokuguguleka. Umzekelo, ipleyiti yokuguguleka ye-5+5 (i-substrate ye-5mm + umaleko we-cladding we-5mm) luhlobo oluqhelekileyo lwesakhiwo, olungagcini nje ngokugcina amandla esakhiwo kodwa lukwaqwalasela noqoqosho kunye nokuguquguquka kokucubungula.

Inkonzo yokucubungula iipleyiti ezingagugiyo ezigqunywe yi-overlay

Ngelixa ibonelela ngeemveliso zepleyiti ezingagugiyo ze-CCO, iWodon iya kubonelela ngeenkonzo zokucubungula ezipheleleyo. Ngokuphathelele ukusika, izixhobo zeplasma okanye zelaser zisetyenziselwa ukusika ngokuchanekileyo, okungekuko nje kuphela ukusebenza kakuhle kwaye kunendawo encinci echaphazeleka bubushushu, kodwa kukwanomgangatho ogqwesileyo wemveliso egqityiweyo.

Ngokuphathelele ukugoba nokwenza, umzekelo, iipleyiti zentsimbi ezidityanisiweyo ezimelana nokuguguleka ze-bimetallic zinokucutshungulwa zibe ziindawo ezigobileyo okanye ezikhonkrithi ukuze kuhlangatyezwane neemfuno zesicelo sezixhobo ezintsonkothileyo. Iinkonzo zokubhola ziquka ukucutshungulwa kwemingxuma ethe tye kunye nemingxuma engaphantsi komhlaba, nto leyo elula ukuqhagamshela ibholiti okanye ukufakwa kwe-welding okulandelayo. Ukongeza, olu hlobo lwepleyiti emelana nokuguguleka lunokuguguleka okuhle kwaye lunokusetyenziselwa ukwenza iindawo ezimelana nokuguguleka ezifana neebhakethi ze-excavator, ii-liners, kunye nee-bushings zenkqubo yokuhambisa.

Inkonzo eyenzelwe wena

Ukuqwalasela umahluko othile kwiimfuno zamashishini ahlukeneyo kunye nezixhobo zezinto ezinganyangekiyo, iWodon ikwabonelela ngezisombululo zepleyiti ezinganyangekiyo ezinobukhulu obulungiselelwe wena. Ubukhulu beleyara yomphezulu, ubungakanani bepleyiti, kunye nezinye iiparameter zinokulungiswa ngokweemfuno zomsebenzisi ukuqinisekisa ukuba imveliso ihambelana ngokuchanekileyo nesicelo sokwenyani. Umzekelo, ekusetyenzisweni kwelayini yepayipi yokuhambisa impahla, iileya ezinkulu zomphezulu kunye neepleyiti ezidityanisiweyo ezinganyangekiyo ngumhlwa zinokubonelelwa ukwandisa ubomi benkonzo.
