Ngemuva kokutholakala kobuchwepheshe be-laser ngo-1960, ukunemba kanye nokuba lula kwama-laser kubonise amandla amakhulu okucubungula okubonakalayo nangaphezulu. Ngenxa yezindleko eziphezulu zasekuqaleni nokusebenza okuphansi kwemithombo ye-laser beam, kwathatha i-laser cladding kuze kube ngama-1980s ukuba yamukelwe embonini yonke (Corbin et al. 2004). Kubonakale kuyindlela ethembisayo yezindlela ezijwayelekile zokushisela i-arc kagesi nezindlela zokuvala, njengoba okokufaka okushisa okuhlanganisiwe kuholela ekuhlanjululweni okuphansi kanye nokwehliswa okuphelele kwamaphutha (Morgado no-Valente 2018).

Emgogodleni wayo, i-laser cladding iyinqubo yokushisela nge-laser lapho ubuhlalu obubodwa buqondaniswa futhi bupakishwe phezu kwe-substrate material. Ngendlela yayo elula, isetshenziselwa ukumboza izindawo zensimbi ngezinsimbi noma ama-carbides. Izinhlelo zokusebenza ezijwayelekile ziwukuqiniswa kwezingxenye zomshini ezisetshenziswa endaweni elimazayo noma ebolayo (Lachmayer et al. 2018). Ukumbozwa kwesitoko esiyindilinga esiyindilinga ngensimbi eqinile futhi engagqoki kuthuthukisa izakhiwo ze-tribological zamagiya namabheringi. Uma kuqhathaniswa nezinye izinqubo zokumboza, inqubo esekwe nge-laser ithambile kakhulu ngakho-ke ukutshalwa kwezimali okuphezulu komthombo we-laser kuvame ukuba wusizo. Ukukhiqiza okungeziwe okuhlanganiswe ne-laser kwavela ngesidingo sokukhanda umdwebo osugugile ufela isitembu sensimbi (Levy et al. 2003). Ngaphezu kwalokho, ukuqiniswa kwezakhiwo ezinobunzima obukhulayo obusetshenziswa embonini yezimoto kungenzeka.

Ngokuvamile, amakhanda enqubo yokuvala i-laser akhona ezimisweni ezimbili ezihlukene, zona ngokwazo ezihlukile ngocingo kanye nempahla ye-powder-based fller. Ngesikhathi esifanayo, zombili izinhlelo zingaklanywa nge-off-axis noma i-coaxial material supply (Lammers et al. 2018).

I-Laser metal deposition in pure cladding applications ngokuvamile isethelwa amanani aphezulu okubekwa. Ngakho-ke, inani elikhulu lezinto zocingo noma ze-powder zengezwa endaweni yokucubungula i-laser off-axially. Ngemisebenzi eyinkimbinkimbi enesengezo enokulungiswa okuphezulu, i-coaxial powder noma ukusethwa kwenozzle yocingo kuyadingeka.

Enye yezinzuzo eziyinhloko ze-laser cladding yokukhiqiza okungeziwe yivolumu enkulu yokwakha, lapho amanye amakamelo okwakha engaba nosayizi wama-cubicmeters amaningi.Ithuba lokwengeza endaweni ekhona ekhululekile ivumela inhlanganisela yomshini ovamile wesivinini esiphezulu kanye nesengezo esikhethekile. ukukhiqiza.

Intuthuko ekuthuthukisweni kwenqubo inika amandla hhayi kuphela ukuguqula inkimbinkimbi, kodwa futhi nokusetshenziswa kwezinto ezikhethekile nezinzima zokushisela. Ukufakwa kwe-laser akukhawulelwe ezinsimbi kuphela, ngisho ne-ceramics noma ama-carbides angasetshenziswa ukuze ahlakazeke endaweni yensimbi ukuze kusebenze izingxenye eziphrintiwe ze-3D.

Isetshenziswa ngokuqapha kwenqubo ethuthukisiwe namalophu okulawula impendulo, ngisho nezinto ezinkulu ezinobude besikhathi bokuphrinta futhi ekugcineni izingxenye zezindiza ezihambisana nokuphepha zingakhiwa futhi zilungiswe.
