Sib Piv Ntawm Nruab Nrab Cov Kev Txhim Kho Cov Nruab Nrab PVD Coatings

Muaj ntau yam PVD coating technologies hnub no, thiab cov technologies tag nrho muaj lawv tus kheej cov yam ntxwv. Evaporation technology, magnetron sputtering technology thiab cathodic arc technology tag nrho muaj lawv tus kheej daim ntawv thov yog hom twg.

Evaporation tshuab yog zoo heev rau cov hniav txheej rau xim xim hlau tsis muaj xim, txheej txheej ntawm workpiece yog qhov zoo heev nrog tsawg roughness, zoo nkauj tsos thiab siab nto zoo. Tab sis qhov adhesion ntawm lo thiab substrate tsis zoo heev.

Txawm hais tias magnetron tshuab ua kom tshuab muaj cov thooj loj loj, tab sis kuj tseem ceeb heev ntawm cov hom phiaj ionize, yog li no hom txheej txheem kom paub meej tias tus ntug thaum lub zog los ntawm cov txheej txheem thiab cov substrate ntau zog. Magnetron tshuab luam yeeb yog tsim rau txheej xim ntawm cov pwm yas.

Cathodic arc tshuab kom cov ionization ntawm ntau tshaj 90% ntawm lub hom phiaj, uas zoo heev txhim kho lub adhesion ntawm txheej thiab substrate. Txawm li cas los xij, vim cathodic arc technology twb tsis muaj mob thiab loj zis tso, qhov tsis zoo ntawm lub txheej ntawm lub txheej. Yog li ntawd, lub cathodic arc technology yog zoo heev rau cov cuab yeej coatings.

Cov paj siv li ntawm cov dej loj peb sib txawv. Vim hais tias qhov siab ionization tus nqi, qhov loj ntawm lub txheej ntawm cathodic arc technology yog me me, uas ua raws li los ntawm magnetron ntses nplej, thiab txheej txheej ntawm cov txheej txheem dej ntws yog cov loj tshaj.

Vim tias txhua txoj kev muaj nws cov ntaub ntawv, cov neeg siv yuav tsum xaiv txoj cai txheej raws li lawv tus kheej cov kev xav tau hauv cov khoom siv tiag tiag los ua qhov zoo tshaj plaws siv nws.
