3. Cov kauj ruam tseem ceeb nyob rau hauv qis-Tsuas Brazing txheej txheem
1) Substrate thiab Pob Zeb Diamond Pre- kev kho mob: Ntxuav cov hlau substrate thiab siv txheej txheej (xws li, npib tsib xee plating). Kho cov pob zeb diamond nto nrog cov txheej txheem metallised (xws li, titanium plating) txhawm rau txhim kho lub wettability thiab kev sib txuas lub zog ntawm cov khoom siv hlau brazing.
2) Ordered Arrangement: Precisely position pob zeb diamond hais rau ntawm lub substrate ua hauj lwm nto raws li predetermined qauv, spacings, thiab orientations. Qhov no tsim lub hauv paus rau kev ua tiav 'txiav txiav'.
3) Daim Ntawv Thov Filler: Muab cov khoom siv ua kom muaj zog (feem ntau nyiaj-, tooj liab-, lossis npib tsib xee- raws li cov khoom muaj zog xws li Ti lossis Cr) hauv daim ntawv, hmoov, lossis muab tshuaj txhuam ib ncig ntawm pob zeb diamond hais.
4) Nqus brazing: Lub workpiece yog muab tso rau hauv lub tshuab nqus tsev brazing rauv. Nyob rau hauv lub tshuab nqus tsev los yog ib qho chaw tiv thaiv, nws yog rhuab saum lub brazing muab tub lim lub melting point. Cov muab tub lim melts, wetting ob lub pob zeb diamond thiab substrate. Cov ntsiab lus chemically react nrog lub pob zeb diamond nto, tsim ib txheej carbide. Kev sib nrig sib diffusion tshwm sim ntawm qhov muab tub lim thiab substrate, tsim kom muaj ib daim ntawv cog lus metallurgical.
5) Txias thiab sib sau ua ke: Tom qab maj mam txias, cov hlau muab tub lim solidifies, ua rau siab - lub zog, siab - kev ncaj ncees sib txuas txheej. Lub pob zeb diamond yog li khov kho "welded" rau lub substrate.
