Corrosion Failure Analysis

Cov ntaub ntawv siv tau: Haum rau ntau yam hlau thiab hlau alloy xws li carbon steel, alloy steel, stainless hlau, duplex steel, npib tsib xee raws alloys, aluminium alloys, tooj liab alloys, titanium alloys, thiab lwm yam.

Cov khoom siv: npog cov hlab ntsha siab, cov kav dej, cov kav dej, cov flanges, cov khoom siv hluav taws xob sib pauv, cov qauv hauv hiav txwv ntawm cov nkoj, cov khoom siv tshuaj, boilers, fasteners, welded lug, thiab ntau yam khoom uas tsis ua hauj lwm nyob rau hauv corrosive ib puag ncig.

Ib puag ncig siv tau: suav nrog corrosive ib puag ncig xws li huab cua, dej hiav txwv, av, acid-base ntsev media, kub thiab siab siab, chloride ions, hydrogen sulfide, circulating dej txias, thiab lwm yam.

Macro tsom xam: kev soj ntsuam zoo li qub, kev sau cov ntaub ntawv corrosion morphology, qhov chaw tsis ua haujlwm, kev txiav txim ua ntej ntawm hom tsis ua haujlwm.

Microscopic tsom xam: metallographic qauv tsom xam, soj ntsuam ntawm corrosion khoom morphology, intergranular corrosion, pitting corrosion, crevice corrosion, kev nyuaj siab corrosion, hydrogen induced cracking thiab lwm yam microscopic yam ntxwv tsom xam.

Kev txheeb xyuas cov khoom sib xyaw: Kev tshuaj xyuas ntawm cov khoom siv matrix muaj pes tsawg leeg, cov khoom muaj pes tsawg leeg corrosion, nto sediment, thiab nruab nrab muaj pes tsawg leeg.

Mechanical Performance Verification: Kev tshuaj xyuas ntawm hardness, tensile, kev cuam tshuam thiab lwm yam khoom los txiav txim siab cov khoom siv thiab kev kho cua sov.

Corrosion hom kev txiav txim siab: suav nrog kev txhim kho corrosion, pitting corrosion, crevice corrosion, intergranular corrosion, galvanic corrosion, kev nyuaj siab corrosion cracking, corrosion qaug zog, hydrogen embrittlement, sulfide kev nyuaj siab tawg, thiab lwm yam.

Corrosion npaum li cas thiab qhov seem ntawm lub neej ntsuas.

Kev tsom xam ntawm kev ua tsis tiav: kev txiav txim siab ntawm ntau yam xws li cov khoom siv, ib puag ncig, kev ntxhov siab, txheej txheem, kev sib dhos, kev siv thiab kev saib xyuas.

Cov lus qhia rau kev tiv thaiv tsis ua hauj lwm thiab kev txhim kho kev ntsuas.
