Laser cladding muaj ntau qhov zoo, suav nrog kev ua kom txias sai (txog 10 ^ 6 K / s), cov txheej txheem qis (feem ntau tsawg dua 5%), cov khoom siv hluav taws xob tsawg thiab kev sib txawv, ntau hom hmoov xaiv, ntau hom cladding txheej thicknesses (0.2 ~ 2.0 hli ib zaug), xaiv cladding muaj peev xwm, tsis tshua muaj khoom noj, thiab yooj yim ntawm automation.
Laser cladding is a rapid solidification process that easily produces fine-grained structures or generates new phases, resulting in a dense coating with a strong metallurgical bond to the substrate. Piv txwv li, lub (CrFeNiAl)100–xMox siab-enttropy alloy txheej muaj lub cev-centered cubic (BCC) theem thiab B2 theem, ua tiav hardness txog li HV0.2 636.6. Ultra-siab-ceev laser cladding (EHLA) cov txheej txheem muaj peev xwm ua kom muaj kev sib xyaw ua ke ntxiv. txheej hnav tsis kam, corrosion kuj, thiab siab -kub tsis kam.
Kev ntsuas qhov zoo ntawm laser cladding txheej yuav tsum tau kuaj macroscopic ntawm cladding channel duab, nto roughness, tawg, porosity, thiab dilution tus nqi, nrog rau kev kuaj xyuas ntawm microstructure. Feem ntau muaj xws li porosity, tawg, deformation, thiab nto roughness. Los ntawm kev txhim kho cov txheej txheem tsis zoo xws li lub zog laser, scanning ceev, thiab hmoov pub tus nqi, los yog los ntawm kev ua hauj lwm sab nraud - cov tswv yim pab, tsis xws luag xws li tawg thiab porosity yuav txo tau zoo.
