Izimbangela Nokuvinjelwa Kwemifantu ku-Laser Cladding kanye Nomphumela Wokuhluleka Kwe-Chiller

Ukwakheka komfantu kuyinselelo evamile ezinqubweni zokuvala i-laser, ngokuvamile okuthinta ikhwalithi nokuqina kwesendlalelo esigqokile. Ukuqonda izimbangela kanye nokusebenzisa izinyathelo zokuvimbela ezisebenzayo kubalulekile ukuze kuzuzwe imiphumela emihle. Ukwengeza, ukugcina umsebenzi ofanele we-chiller yamanzi kubalulekile, njengoba ukwehluleka kokupholisa kungandisa kakhulu ingozi yokuqhekeka.

Izimbangela Ezivamile Zemifantu ku-Laser Cladding

1. Ukucindezeleka Okushisayo: Enye yezimbangela eziyinhloko zokuqhekeka ukucindezeleka okushisayo okubangelwa ukungafani kwe-coefficient of thermal expansion (CTE) phakathi kwezinto eziyisisekelo kanye nesendlalelo sokuvala. Ngesikhathi sokupholisa, ukugxila kwengcindezi kukhula esibonakalayo, okwandisa amathuba okuqhekeka.

2. Ukupholisa Okusheshayo: Uma izinga lokupholisa lishesha kakhulu, ingcindezi eyinsalela ngaphakathi kwempahla ayikwazi ukukhululwa ngempumelelo, okuholela ekwakhekeni kwama-crack, ikakhulukazi ezintweni eziqinile noma eziphukayo.

3. Izinto ezibonakalayo: Ingozi yokuqhekeka iyanda lapho usebenzisa ama-substrates anokuqina okuphezulu (isb, izinto ezicinyiwe noma ezifakwe i-carburized/nitrided) noma izimpushana ezinobunzima obuphezulu ngokweqile noma ezingahambelani kahle. Ama-substrates anezendlalelo zokukhathala noma ikhwalithi yendawo engahambisani nayo ingaba nomthelela ekuqhekekeni.

Izinyathelo Zokuvimbela

1. Ukuthuthukisa Amapharamitha Enqubo: Ukulungisa ngokucophelela amandla e-laser, isivinini sokuskena, nezinga lokuphakela kwempushana kusiza ukulawula izinga lokushisa lechibi elincibilikayo nezinga lokupholisa, kunciphisa ama-gradients ashisayo kanye nengozi yokuqhekeka.

2. Ukushisa Ngaphambi Kokuqala Nokupholisa Okulawulwayo: Ukushisa kuqala isisekelo kanye nokusebenzisa ukupholisa okuhamba kancane, okulawulwayo ngemuva kokuvala kungasiza ekudambiseni ukucindezeleka okuyinsalela, kwehlise amandla okuthuthukiswa kokuqhekeka.

3. Ukukhetha Okubalulekile Kwempushana: Ukukhetha izimpushana ezihambisana nesisekelo sezinto ezinwebekayo ezishisayo nobulukhuni kubalulekile. Ukugwema ubulukhuni obedlulele noma ukungahambisani nokushisa kunciphisa ukucindezeleka kwangaphakathi nokwakheka kokuqhekeka.

Umthelela Wokuhluleka Kwe-Chiller Ekubunjweni Kwe-Crack

I-water chiller idlala indima ebalulekile ekulawuleni okushisayo kwemishini yokuvala i-laser. Uma isibandisi samanzi sihluleka , kungaholela ekushiseni ngokweqile komthombo we-laser noma izingxenye ezibalulekile, kubeke engcupheni ukuzinza kwenqubo. Ukushisa ngokweqile kungase kuguqule ukuncibilika kwe-pool dynamics futhi kwandise ngokuphawulekayo ingcindezi eyinsalela kundaba, kube nomthelela ngokuqondile ekwakhekeni kwemifantu. Ukuqinisekisa ukusebenza kwe-chiller okuthembekile ngakho-ke kubalulekile ekugcineni ikhwalithi yokugqoka kanye nokuvimbela ukukhubazeka kwesakhiwo.

Isiphetho

Imifantu ekufakweni kwe-laser ingancishiswa ngempumelelo ngokuphatha ingcindezi yokushisa, ukukhetha izinto ezifanele, nokugcina izimo zokupholisa ezizinzile. I-chiller yamanzi ethembekile iyingxenye ebalulekile yesistimu, esiza ukuqinisekisa ukulawulwa okungaguquki kwezinga lokushisa nokuthembeka kwemishini yesikhathi eside.
