Imibuzo Ejwayelekile Mayelana Nokwelashwa Kokushisa Kwe-Laser

Ukwelashwa kwe-laser ukushisa kuba ubuchwepheshe obubalulekile ekukhiqizeni kwesimanje, okunikeza ukunemba okuphezulu, izinzuzo zemvelo, kanye nokuvumelana nezimo okuhle kakhulu ezintweni ezintsha. Ngezansi, siphendula eminye yemibuzo evame kakhulu ngale ndlela yokwelapha engaphezulu.

Isiphi isimiso esiyisisekelo sokwelashwa kokushisa kwe-laser?
Ukwelashwa kokushisa kwe-laser kusebenzisa i-laser density high-energy ukuze kushise ngokushesha futhi kupholise ingaphezulu lento. Esikhathini esifushane kakhulu, i-laser inyusa izinga lokushisa elingaphezulu kwephuzu le-austenitizing. Njengoba ukushisa kuhlakazeka ngokushesha ngokusebenzisa i-thermal conductivity yayo, i-ultrafine martensitic kwakheka. Le nqubo ithuthukisa kakhulu ubulukhuni bobuso, ukumelana nokugqoka, namandla okukhathala.

Ukwelashwa kokushisa kwe-laser kubonisa kanjani ukunemba nokuvumelana nezimo?
Enye yezinzuzo ezinkulu zobuchwepheshe be-laser yikhono layo lokulawula usayizi wendawo ye-beam kuze kufike ezingeni le-micrometer. Lokhu kuvumela ukuqiniswa kwendawo kwamajiyometri ayinkimbinkimbi njengemisele yokukhunta, amazinyo egiya, nezinye izindawo eziyinkimbinkimbi. Embonini yezimoto, ukwelashwa kwe-laser kusetshenziswa kakhulu ukuqinisa okunembile kwezingxenye zenjini. Ekukhiqizeni isikhunta, kuthuthukisa kuphela izindawo ezigqoke kakhulu, ukwandisa impilo yesevisi ngaphandle kokuthinta lonke ithuluzi.

Kungani ukwelashwa kokushisa kwe-laser kuthathwa njengokuhambisana nemvelo?
Ngokungafani nezindlela zendabuko zokwelapha ukushisa, ukwelashwa kwe-laser akudingi amanzi, uwoyela, noma enye imidiya yokupholisa phakathi nokusebenza. Lokhu kuqeda ukukhishwa kwamanzi angcolile futhi kunciphisa ukungcoliswa, ukuhambisana nemigomo yokukhiqiza okuluhlaza. Inqubo ehlanzekile futhi eqhubekayo ikwenza kube ukukhetha okuhle ezimbonini ezihlose ukwehlisa indawo yazo yemvelo.

Kuvumelana nezimo kangakanani ukwelashwa kokushisa kwe-laser ezintweni ezintsha?
Njengoba izinto ezingasindi zithola ukuduma, ikakhulukazi embonini yezimoto zamandla amasha, izinqubo zokwelashwa kwe-laser ezizinikele zenzelwe ama-alloys nezinhlanganisela. Isibonelo, ama-alloys e-aluminium azuza ezakhiweni zekristalu ezithuthukisiwe, okuholela ekubeni namandla nokuqina okuphezulu. Izinhlanganisela ze-carbon fiber zingafinyelela izakhiwo ezingcono ezingaphezulu nokusebenza okuqinile kwesibopho, zisekele isidingo esikhulayo sezinto ezingasindi, ezihlala isikhathi eside ezinhlelweni zobunjiniyela ezithuthukile.
