"Ubuso obunzima" kunye "nokugqoka" ngamagama amabini ahlala esetyenziswa ngokufanayo, eneneni zizicelo ezahlukeneyo.I-Hardfacing yinkqubo ye-welding esebenza kwindawo ephezulu yokunxiba ukongeza ukhuseleko kunye nokwandisa ubomi bento. Iqulethe i-carbides kwaye, kwiimeko ezininzi, le yi-cemented carbide.

Ukufakwa kwentsimbi kukufakwa kwesinyithi esingafaniyo kumphezulu wesinye isinyithi. Ukwaleka kuya kusebenzisa imathiriyeli eyogqunyiweyo efana nesiseko semathiriyeli kodwa kwiimeko ezininzi kusetyenziswa imathiriyeli eyahlukileyo ukunika ipropathi enenzuzo kuloo nxalenye yecandelo, njengobunzima obuphezulu, ukuxhathisa umhlwa, okanye ukuhlangabezana nomsebenzi wokuhlaziya. Njengokugquma, i-laser hardfacing ayinakwenziwa ngoomatshini kwaye kufuneka icolwe.

Ubuso obuqinileyo VS. Inkqubo yokugquma

Nangona ukuqina kunye nokugquma ziinkqubo zokwaleka komphezulu ezohlukileyo kwiimpawu ezibonakalayo ezihlangabezana neemfuno ezahlukeneyo, zombini zinokufezekiswa kusetyenziswa iinkqubo ezifanayo:

•      IiLaser

•      Thermal spray

•      I-Flux-cored arc welding okanye i-FCAW

•      ukuwelda kwePlasma Transfer Arc [PTA]

Ukukhetha phakathi kokuqina kunye nokugquma kwehla kwiimpawu ofuna ukuzinikezela, izinto ezibandakanyekayo, kunye nokuqonda okusingqongileyo apho umphezulu uphantsi kwayo. Kwi-hardfacing, i-carbide enzima, engagugiyo / idiphozithi yesinyithi ingasetyenziswa nge-laser, ukutshiza nge-thermal, i-spray-fuse, okanye i-welding. Ukutshiza nge-thermal kokona kulungileyo kwizinto ezinobuntununtunu bokuphazamiseka kobushushu, ngokuchaseneyo ne-spray-fuse efuna ukutshizwa kwedangatye kunye nokudibanisa ngetotshi. I-spray ye-Thermal ayikho inkqubo ye-welding; ke ngoko, amandla ebhondi aphantsi kakhulu xa kuthelekiswa ne-welded okanye ibrazed overlay. I-weld hardfacing yendabuko ingasetyenziselwa ukusebenzisa umaleko obunzima kakhulu (ukuya kuthi ga kwi-10's ye-mm) yezinto ezinxitywayo. I-Laser hardfacing ineenzuzo ngaphezu kwezinye iinkqubo ngokuyintloko kuba yinkqubo ye-welding enobushushu obuphantsi, i-dilution ephantsi, kunye nokuchithwa okuncinci kwe-carbide. Konke oku kuvumela ukukwazi ukufezekisa izingqimba eziqinileyo zobuso obuqinileyo.

Ukwaleka yinkqubo yokwaleka kweweld evelisa umphezulu omtsha ngokupheleleyo onokuthi usetyenziswe kunye neentlobo ezininzi zemathiriyeli yokwaleka ngeendlela ezahlukeneyo ezinje ngomgubo, ucingo, okanye iingcingo ezinocingo. Ngaphezu koko, iinkqubo zokwaleka zesiNtu zinokusetyenziswa njengoko kudweliswe ngasentla. Kanye nje nge-laser hardfacing, i-laser cladding inezibonelelo ngaphezulu kwezinye iinkqubo kuba yinkqubo ye-welding enobushushu obuphantsi kunye nokuhlanjululwa okuphantsi. Konke oku kuvumela ukukwazi ukufezekisa izigqubuthelo ezinqabileyo kakhulu.

Ukuqina kweLaser kunye nokugquma kusetyenziswa phantse kuyo yonke imarike yoshishino enezicelo ezinje:

•      I-oyile negesi

•      Izithuthi

•      Izixhobo zokwakha

•      Ezolimo

•      Ukwembiwa kwemigodi

•      Umkhosi

•      Ukuveliswa kwamandla

•      Ukulungiswa nokuhlaziywa kwezixhobo, iibhleyidi zeinjini yomoya, kunye neenjini

I-Laser hardfacing kunye ne-laser cladding zombini zibonelela ngezibonelelo zokuphazamiseka okuncinci kwe-thermal, imveliso ephezulu, kunye nokusebenza kakuhle kweendleko.

IiLasers kwi-Hardfacing kunye neeNkqubo zokugquma

Ukusebenzisa i-laser njengomthombo wobushushu kwi-hardfacing kunye ne-cladding kunika ukuchaneka kunye nelona nani liphantsi lokuhlanjululwa kweekhemikhali ukuwelda izixhobo ezimbini. Ibonelela ngendlela enexabiso eliphantsi lokusebenzisa izinto ezingaphantsi kwexabiso eliphantsi ngokufaka i-weld overlay, ebonelela ngokutya, i-oxidation, ukunxiba kunye nokumelana nobushushu. Izinga eliphezulu lemveliso apho iimveliso zinokugqitywa kudityaniswe nezinto eziluncedo zeendleko zenza i-laser cladding kunye ne-hardfacing ibe lukhetho oludumileyo kumashishini amaninzi.
