Daim ntawv thov ntawm Electroless Nickel Plating ntawm Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob hauv Hlau Raws li Hmoov Metallurgical Parts
Cov electroplated npib tsib xee qhov chaw tau rhuab mus rau 300 degree, thiab tom qab raug tshem tawm, muaj ib tug tshwm sim ntawm txheej detachment thaum quenched nyob rau hauv dej. Txawm li cas los xij, cov tshuaj npib tsib xee txheej tau rhuab mus rau 600 degree, thiab tom qab tshem tawm, tsis muaj qhov tshwm sim tshwm sim thaum quenched hauv dej.
3.2 Corrosion resistance test
Sib piv cov corrosion kuj ntawm electroplated npib tsib xee thiab chemically plated npib tsib xee hmoov metallurgy qhov chaw nyob rau hauv tib yam kev sim. 321CO gas corrosion test
Muab cov hmoov metallurgy qhov chaw electroplated nrog npib tsib xee thiab chemically plated nrog npib tsib xee nyob rau hauv ib puag ncig ntawm chav tsev kub, atmospheric siab, thiab CO concentration ntawm 1% mus rau 2 feem pua, thiab ntsuas lub sij hawm rau xeb me ntsis tshwm nyob rau hauv lub txheej. Qhov tshwm sim yog xeb pob tshwm nyob rau saum npoo ntawm electroplated npib tsib xee qhov chaw tom qab 312 teev, thiab xeb me ntsis tshwm rau saum npoo ntawm chemically plated npib tsib xee qhov chaw tom qab 360 teev. 3.2.2 NaCl tov tshuaj corrosion
Npaj ib 2000mL NaCl tov ntawm ib tug concentration ntawm 50g / L, thiab ces muab faib mus rau hauv ob 1000mL beakers. Tom qab ntawd, dai cov tshuaj plated npib tsib xee hmoov metallurgy thiab electroplated npib tsib xee qhov chaw uas tau raug khi nrog nylon hlau nyob nruab nrab ntawm cov tshuaj. Qhov tshwm sim yog tias xeb me ntsis tshwm rau ntawm qhov chaw ntawm electroplated npib tsib xee hmoov metallurgy qhov chaw tom qab 76 teev, thiab cov pob xeb tsuas yog tshwm sim rau ntawm qhov chaw ntawm chemically plated npib tsib xee tom qab 100 teev.
3.3 Stability Test ntawm Electroless Nickel Plating Txheej
Muab cov electroless npib tsib xee plated qhov chaw (tsev neeg knitting tshuab sawb) nyob rau hauv ib lub thawv louver sab nraum zoov, kom cov khoom tsis raug rau lub hnub ncaj qha thiab dej nag yaig nyob rau hauv ib txwm siab, thiab huab cua nyob rau hauv lub louver lub thawv yog ventilated. Nyob rau hauv me me muaj roj nruab nrab corrosion (sib npaug rau suburban atmospheric tej yam kev mob, qhov twg cov huab cua yog me ntsis acidic thiab lub ambient kub yog nyob nruab nrab ntawm 6 thiab 36 degree), cov khoom tseem ci ntsa iab raws li daim iav txij li thaum muab tso rau hauv lub kaum hli ntuj 1999 (nws tau peb. xyoo), qhia txog kev ruaj ntseg zoo thiab kav ntev ntawm cov tshuaj nickel plating txheej, ua tau raws li qhov yuav tsum tau ua ntawm kev siv tswv yim.
