Uhlalutyo olunzulu lweNkqubo yokuGqiba ngeLaser: Imigaqo, uHlelo kunye noKhetho lwezinto
Itekhnoloji yokugquma nge-laser imele indlela yobunjineli bomphezulu obuphambili. Umgaqo wayo usekubekeni ngononophelo izinto zokugquma ezikhethiweyo kumphezulu we-substrate kwiindlela ezahlukeneyo zokuzalisa. Njengoko umqadi we-laser onamandla aphezulu ukhanyisa loo ndawo, ayinyibiliki nje kuphela izinto zokugquma, kodwa nomaleko omncinci womphezulu we-substrate uyanyibilika ngaxeshanye. Ngokuqiniswa ngokukhawuleza, kwenziwa uqweqwe lomphezulu olunesantya esiphantsi kakhulu sokunyibilika. Olu qweqwe lwakha umanyano lwe-metallurgical nezinto ze-substrate, olubaluleke kakhulu kuba lunokuphucula kakhulu iipropati ezininzi zomphezulu we-substrate. Umzekelo, lunokuphucula kakhulu ukumelana nokuguguleka, luvumela izinto ukuba zinyamezele ukungqubana okungakumbi; lunyuse ukumelana nokugqwala, lukhusele izinto kwiintsholongwane zeekhemikhali; lunyuse ukumelana nobushushu kunye nokuxhathisa i-oxidation, luvumele iindawo ukuba zisebenze kwiindawo ezinobushushu obuphezulu kunye ne-oxidative; kwaye lutshintshe neepropati zombane.
Ngokwendalo yezinto zokugquma nge-laser kunye nendlela ezidibana ngayo nomqadi we-laser, iiteknoloji eziqhelekileyo zokugquma nge-laser zinokuhlulwahlulwa. Itekhnoloji yokugquma nge-laser yokutyisa i-coaxial powder idla ngokusebenzisa i-laser ye-semiconductor fiber output kunye ne-disc-type gas-carrying powder feeder. Intloko yokugquma inoyilo lwendawo ejikelezileyo enokukhanya okuphakathi kunye nokuba yi-annular powder feeding okanye i-multi-beam powder feeding ejikeleze umqadi, kunye nomjelo wegesi okhuselayo ozinikeleyo. Ngexesha lenkqubo yokugquma, umqadi we-powder, umqadi we-laser, kunye nokuhamba kwegesi ekhuselayo kudibana kwindawo enye, kudala ichibi elinyibilikisiweyo kwindawo ephambili. Njengoko intloko yokugquma kunye ne-workpiece zihamba ngokuhambelana, ukugquma okuqhubekayo nomgangatho ophezulu kwenziwa kancinci kancinci kumphezulu we-workpiece. Itekhnoloji yokugquma nge-laser yokutyisa i-paraxial powder, eyaziwa ngokuba yitekhnoloji yokugquma nge-laser yokugquma nge-lateral powder, ineempawu zayo ezizodwa kwiinkqubo zokugquma nge-powder kunye ne-beam. Itekhnoloji yokugquma nge-laser ekhawulezayo, ngamanye amaxesha ebizwa ngokuba yitekhnoloji yokugquma nge-laser ekhawulezayo, igxile ekufezekiseni amazinga okugcina ukugquma ngokukhawuleza ngelixa igcina umgangatho wokugquma. Itekhnoloji yokugquma nge-laser yentambo ekhawulezayo isebenzisa izinto ezimile okwentambo, iveza indlela eyahlukileyo xa ithelekiswa neendlela zokugquma ezisekelwe kumgubo. Indlela nganye kwezi yokuhlela ineemeko zayo zokusetyenziswa kunye neenzuzo, nto leyo eyenza ukugquma nge-laser kube yitekhnoloji eguquguqukayo kakhulu neguquguqukayo kwiinkalo ezahlukeneyo zoshishino.
