Nyob rau hauv kev nruam kev lag luam ntawm kev hloov kho tshuab, qhov kev siv tshuab electrospark tso tau tawm. Cov txheej txheem nyob rau hauv cov nyhuv ntawm cov hluav taws xob, lub siab kub siab, siab hauv niam txiv hlau, infiltration ntawm ion lub xeev ntawm cov hlau ceramic khoom tib lub sijhawm, tsim ntawm qhov sib xyaw metallurgical ua ke, thiab instantaneous theem transformation hauv niam txiv hlau nto rau tib lub sijhawm, tsim cov martensite thiab cov tshuaj nplua austenitic (20) .Qhov txheej txheem no txawv ntawm kev vuam, cov plating plating los yog lub caij infiltration. Nws yuav tsum nyob nruab nrab ntawm ob .Nws ua zoo siv cov khoom ua haujlwm tsis zoo, kub kub thiab corrosion ntawm hlau ceramic ntaub ntawv.Die - casting tuag ntws kho yog ib txoj kev tshiab.
