Ntawm Qhov Chaw Metallographic Examination

Cov hlau dub: hlau, cam khwb cia hlau (grey cam khwb cia hlau / ductile hlau / vermicular cam khwb cia hlau), alloy structural steel, stainless hlau, cuab yeej steel, bearing steel, thiab lwm yam

Nonferrous hlau: txhuas thiab txhuas alloys, tooj liab thiab tooj liab alloys, magnesium thiab magnesium alloys, titanium thiab titanium alloys, zinc alloys, thiab lwm yam

Cov ntaub ntawv tshwj xeeb: tawv alloys, siab - kub alloys, precision alloys, precious hlau, hmoov metallurgy cov ntaub ntawv, thiab lwm yam

Vuam pob qij txha: weld seam, tshav kub cuam tshuam cheeb tsam, fusion kab microstructure thiab kuaj pom qhov tsis xws luag

Thaum tshav kub kub kho qhov chaw: microstructure thiab hardening txheej kuaj ntawm quenched, tempered, normalized, annealed, carburized, nitrided, thiab carbonitrided qhov chaw

Txheej txheej txheej: thickness thiab microstructure kuaj ntawm plating, txheej, tshuaj tsuag txheej, thiab oxide txheej

Failure Analysis: Metallographic Analysis ntawm Failure Uas xws li Fracture, Corrosion, thiab hnav ntawm hlau Cheebtsam

Tsawg magnification lub koom haum thiab tsis xws luag: looseness, cais, shrinkage, npuas, tawg, inclusions, folds, dawb me ntsis, thiab lwm yam
Sulfur print test: xyuas qhov kev faib tawm thiab cais cov sulfur hauv cov hlau
Ntauwd Test: Ntsuam xyuas qhov tsis xws luag thiab sab hauv zoo ntawm cov hlau
Macroscopic tsom xam ntawm pob txha pob txha: microstructure soj ntsuam: morphology thiab kev faib tawm ntawm ferrite, austenite, pearlite, martensite, bainite thiab lwm yam microstructures
Grain size rating: nruab nrab grain loj, grain loj faib, grain ciam yam ntxwv nrhiav kom tau
Kev ntsuam xyuas ntawm cov tsis yog{0}}hlau suav nrog: Chav A (sulfides), Chav Kawm B (alumina), Chav Kawm C (silicates), Chav Kawm D (spherical oxides) kev ntsuas
Kev tsom xam theem thib ob: txheeb xyuas cov theem precipitated, tsom xam morphology, thiab kev txiav txim siab cov ntsiab lus
Kev txiav txim siab ntawm hardened txheej tob: ntsuas thickness ntawm carburized txheej, nitrided txheej, carbonitrided txheej, thiab quenched hardened txheej
Kev ntsuas qhov tob ntawm decarburization txheej: ntsuas thickness ntawm tag nrho decarburized txheej thiab ib nrab decarburized txheej
Microscopic defect detection: microcracks, pores, porosity, intergranular corrosion, thiab lwm yam
Kev ntsuam xyuas kev sib koom ua ke: ntsuas qhov sib xws thiab kev sib cais ntawm cov khoom siv
Vuam microstructure tsom xam: nrhiav pom ntawm vuam microstructure, tshav kub cuam tshuam cheeb tsam microstructure, thiab fusion kab yam ntxwv
Graphite morphology tsom xam: muab qhab nia hom, qhov loj me, thiab kev faib tawm ntawm graphite hauv cam khwb cia hlau los txiav txim siab hom pob txha thiab keeb kwm
