Pwm yog siv dav, thiab feem ntau cov khoom xav tau pwm tsim. Lub neej kev pab cuam ntawm pwm nyob ntawm nws lub peev xwm los tiv thaiv kev hnav thiab kev puas tsuaj. Thaum nws hnav ntau dhau los yog kev puas tsuaj los ntawm mechanically, nws yog qhov nyuaj los kho qhov puas ntawm cov duab, ces nws tsuas tuaj yeem yuav lossis kho cov pwm tshiab. Cov txheej txheem tsim pwm yog qhov nyuaj, lub voj voog ntau lawm ntev, thiab cov nqi ua haujlwm siab. Yog li ntawd, nws yog undoubtedly ntawm cov txiaj ntsim kev lag luam tseem ceeb los kho thiab rov siv cov pwm ua tsis tiav.
Muaj ntau txoj hauv kev los kho cov pwm, xws li hluav taws xob hluav taws xob, argon arc vuam, laser surfacing, txhuam plating thiab lwm yam. Laser cladding tshuab rau kev kho pwm muaj nws qhov tshwj xeeb zoo. Cov ntaub ntawv hmoov yog hloov tau thiab hloov tau, ua tau raws li cov kev xav tau ntawm kev ua haujlwm sib txawv, thiab tuaj yeem npaj ntau hom hnav-tiv taus, kub-resistant thiab yaig resistant coatings, txawm tias gradient coatings. Cov ntaub ntawv txheej tuaj yeem yog cobalt raws, nickel raws li cov khoom siv ceramic.
Piv nrog rau cov tsoos arc kho vuam tshuab, laser cladding muaj tsawg tshav kub input, tsawg tshav kub nyhuv ntawm lub substrate, thiab tsawg residual kev nyuaj siab nyob rau hauv lub kho cheeb tsam; Thiab nws muaj precision siab, uas muaj peev xwm paub qhov tseeb kho ntawm me me tsis xws luag ntawm high-qib pwm.
