Q1: Dab tsi ASTM cov qauv txheej txheem kev sim ntawm txhuas alloys?
ASTM E8 / E8M txhais Tensile sim cov qauv rau cov neeg tau txais / lub zog kawg. ASTM B557 them rau kev sim ntawm cov khoom siv tau. ASTM E18 qhia meej rockwell hardness teev (piv txwv li, nyhav rau extrusions). ASTM E290 ua yuam kev khoov kuaj rau kev muaj peev xwm. Cov ntaub ntawv pov thawj yuav tsum ua raws ISO / IEC 17025 evreditation.
Q2: Yuav ua li cas rau eddy kev soj ntsuam pom cov flasurface supres nyob rau hauv txhuas tubing?
High - zaus} zaus hluav taws xob hauv cov khoom siv hluav taws xob enddy hauv cov khoom. Qhov khuam cuam cuam tshuam tam sim no ntws, hloov kho coil impedance. Kev ntsuas theem ntsuas pom qhov txawv ntawm qhov sib txawv ntawm kev hloov pauv. Caw kaw lus tshuab luam tawm ntawm 60 m / min nrog 0.5 hli kev daws teeb meem. Calibration thaiv nrog EDM tsis yog kom ua tau raug qhov tseeb.
Q3: Vim li cas thiaj kho tau kho qhov tseeb rau cov ntaub ntawv pov thawj?
Txim taws spectrometry qhia cov ntsiab xws li mg, si, cu tsis dhau 0.01% tseeb. PMI (Cov Khoom Siv Zoo) tiv thaiv cov khoom sib xyaw- Ups. Handheld XRF Phom Pab Cov Ntawv Qhia Cov Khoom Siv Khoom Muag Khoom. Kuaj ICP -}} eses analyzes trace impurities (<10 ppm). Certificates of Analysis must meet EN 10204 3.1 standards.
Q4: Dab tsi metallurgical cov yam ntxwv txhais tau yooj yim Aluminium npau taws tsim?
F - Tiab (li - ci) siv rau tsis {{} {} kho cov khoom. H {- Temers (piv txwv li, H32) qhia txog kev ua kom tawv nqaij tawv nrog ib nrab ua si. T - Tempers (piv txwv li, T6) koom nrog kev daws teeb meem kub thiab kev laus. Ncab qib (TXX51) tswj cov kev ntxhov siab uas muaj teeb meem. Cov neeg muaj hnub nyoog aging / kub txiav txim siab ua lub siab tawv.
Q5: Yuav ua li cas ntsev tsuag tshuaj ntsuam xyuas qhov siv tau corrosion tsis kam rau ISO 9227?
Cov qauv kuaj raug rau 5% Nacl pos pos huab ntawm 35℃hauv kev xeem lag. Cyclic Testing (CCT) COMPORPORDENDENCE DUS / Qhuav Kaujs rau Tiag- Lub Ntiaj Teb Simulation. Kev Kawm Txuj Ci Kev Ntsuas Hluav Taws Kub Kub Kub (ASTM D714) thiab cov kws tu npe (Astm D1654). Automotive specs yuav tsum tau 1, 000+} teev yam tsis muaj xeb liab. Zinc Chromate Primers Ob Chav Kev Tiv Thaiv Lifesespan.
