I-thermal spray yindlela yokugquma etshiza izinto ezishushu phezu komphezulu ukuze zigqunywe kwaye zenze ukuba zirhawuzeke, zibole, zikhukuliseke, ziqhekeke okanye zithintelwe kukuqhekeka. Izinto ezahlukeneyo zingasetyenziswa kwi-thermal spray, kodwa ezona zinto ziqhelekileyo ziintsimbi, iiceramics kunye neeplastiki. Izinto (okanye i-feedstock) zifudunyezwa ngombane (i-plasma okanye i-arc) okanye ngeendlela zeekhemikhali (ilangatye lokutsha) ukuze zibe ngumjelo wee-particles ezahlulwe ngokukhawuleza kwimeko enyibilikisiweyo okanye enyibilikisiweyo kancinci ethintela i-substrate ukuvelisa i-coating. I-feedstock inokuba ngohlobo lwentonga, ucingo, umgubo okanye ulwelo.
Isifutho esishushu sidla ngokwenziwa ukukhusela okanye ukulungisa izinto ezikumphezulu. Enye inzuzo yesifutho esishushu kukuba sigquma izinto ezikumphezulu ngesithintelo esikhuselayo. Umzekelo, umphezulu ogqunywe ngesinyithi esomeleleyo uya kuba nokumelana nokuguguleka, ubushushu, ukukrweleka. Enye inzuzo kukuba isifutho esishushu sinokulungisa izinto ezikumphezulu. Inxalenye egugileyo okanye ebolileyo inokutshizwa ngeengubo zokubuyisela. Nangona ifutho esishushu singongezi mandla kwinxalenye, yindlela ekhawulezayo neyongayo yokulungisa ubukhulu bezinto. Imisebenzi yokugaya elandelayo idla ngokufuneka ukuze kuthambise umphezulu wengubo kunye nokuzisa imilinganiselo yokugqibela kwiindlela ezifanelekileyo zokunyamezela.Iibhanti zokusantisa idayimanizisetyenziswa kakhulu kwimisebenzi yokugaya.
Iingenelo eziphambili kunye neempawu ze-thermal spray njengenkqubo yokugquma zishwankathelwe apha ngezantsi:
● Ayifuni naziphi na iikhompawundi zendalo eziguquguqukayo (ii-VOC) eziyingozi ebantwini nakwindalo esingqongileyo.
●Izixhobo ezipheleleyo zingasetyenziswa njengezondlo: iintsimbi, ii-alloys, iiseramikhi, ii-cermets, ii-carbides, ii-polymers kunye neeplastiki.
● Iingubo zokutshiza ezishushu zibotshelelwe ngoomatshini kwi-substrate. Zingatshiza izinto zokutshiza ezingahambelaniyo ne-substrate ngokwesinyithi.
● Ingatshiza izinto zokugquma ngeqondo lokunyibilika eliphezulu kunelo lesiseko.
● Iingubo zokutshiza ezishushu zingafakwa ngesandla nangoomatshini.
● Iingubo ezingqindilili zingafakwa ngamanani aphezulu okufaka.
● Uninzi lweendawo zinokutshizwa ngonyango oluncinci okanye olungenalo kwaphela ngaphambi kobushushu okanye emva kobushushu, kwaye ukuphazamiseka kweendawo akuncinci.
● Iinxalenye zingakhiwa kwakhona ngokukhawuleza nangexabiso eliphantsi, kwaye ngokuqhelekileyo ngexabiso eliphantsi kunelokutshintshwa.
● Ngokusebenzisa izinto ezikumgangatho ophezulu kwi-thermal spray coating, ubomi bezinto ezintsha bunokwandiswa.
Kukho iintlobo ezahlukeneyo zeenkqubo zokugquma nge-thermal spray. Zahlukile kwindlela ezisebenzisa ngayo amandla obushushu kunye ne-kinetic kwizinto ezivela kuzo, uhlobo lwezinto ezivela kuzo kunye nesantya kunye namaqondo obushushu elangatye. Inkqubo nganye ineengenelo kunye neengxaki, kwaye ezinye zilungiselelwe iintlobo ezithile zokugquma.
Iinkqubo zokutshiza ngobushushu bezisetyenziswa kakhulu iminyaka emininzi kuzo zonke iindawo eziphambili zoshishino lobunjineli kuquka ukuveliswa kweeturbine zegesi, iinjini zedizili, iibheringi, iijenali, iimpompo, iicompressors kunye nezixhobo zentsimi yeoyile, kunye nokufakelwa kwezixhobo zonyango. Izixhobo zakutshanje kunye nophuhliso lweenkqubo luphucule umgangatho kwaye lwandise uluhlu olunokwenzeka lwezogquma zokutshiza ngobushushu.
