Kormeerka tayada muuqaalka ee foornada

Kormeerka tayada muuqaalka guud ahaan waa kormeer aan burburin, badanaa isha qaawan ama kormeerka muraayadaha weyneeya oo hooseeya, haddii loo baahdo, sidoo kale isticmaal habka kormeerka aan burburin.
Hababka kormeerka tayada gudaha eefoorjaro culuswaxaa lagu soo koobi karaa sida: kormeerka ururrada makroscopic, kormeerka ururrada yar yar, kormeerka guryaha farsamada, falanqaynta halabuurka kiimikada iyo baaritaanka aan burburin.
Tijaabada makroscopic microstructure waa nooc tijaabo ah oo lagu eegayo laguna falanqeynayo sifooyinka qaab-dhismeed yar ee tamarta yarbeen abuurashomuraayad weyn oo muuqaal ah ama awood yar. Hababka caadiga ah ee loo isticmaalo baaritaanka qaab-dhismeedka macroscopic eebeen abuurashowaa habka daxalka hoose (oo ay ku jiraan daxalka kulaylka, daxalka qabow iyo habka daxalka electrolytic), tijaabada jabka iyo habka daabacaadda sulfur.

Xeerka kormeerka qaab-dhismeedku waa in la isticmaalo mikroskoob fudud si loo hubiyo qaab-dhismeed yarbeen abuurashooo ah qalab kala duwan. Alaabta baadhista guud ahaan waxa ka mid ah cabbirka hadhuudhka gudaha, ama cabbirka hadhuudhka ee heerkul cayiman, ie cabbirka hadhuudhka dhabta ah, ku darista aan biraha ahayn, qaab-dhismeed yar sida lakabka decarburization, homogeneity carbide eutectic, kulayl xad dhaaf ah, gubasho iyo qaab-dhismeed yar oo kale oo loo baahan yahay, iwm.
Guryaha makaanikada iyo kormeerka waxqabadka habka waa inay ahaato daawaynta kulaylka ugu dambeeyabeen abuurashoiyo qaybo tijaabo ah oo loo habeeyey muunad cayiman ka dib isticmaalka mishiinka baadhista xajinta, mishiinka baadhista saamaynta, mishiinka baadhista adkaysiga, mishiinka baadhista daalka, tijaabiyaha adkaanta iyo qalabyada kale si loo go'aamiyo sifooyinka farsamada iyo habka qiyamka waxqabadka.
Tijaabada ka kooban kiimikada guud ahaan waa isticmaalka falanqaynta kiimikada ama falanqaynta spectral ee falanqaynta qaybaha been abuurka ah falanqaynta iyo tijaabinta, iyada oo horumarinta sayniska iyo tignoolajiyada, labadaba falanqaynta kiimikada iyo falanqaynta spectral ee falanqaynteeda macnaheedu waa horumar. Falanqaynta spectral, hadda ma aha mid si fudud loo isticmaalo habka spectral iyo habka spectroscopic si loo fuliyo falanqaynta qaybaha, soo ifbaxa spectrometer photoelectric ma aha oo kaliya falanqaynta degdega ah, laakiin sidoo kale waxay si weyn u wanaajisaa saxnaanta, iyo soo bixitaanka plasma photoelectric spectrometer ayaa si weyn u hagaajiyay falanqaynta. saxnaanta, saxnaanta falanqaynteeda waxay gaari kartaa heerka 10-6, Habkani wuxuu aad waxtar ugu leeyahay baarista raadadka wasakhda waxyeelada leh sida Pb, As, Sn, Sb, Bi ee foornada superalloy.
Kor ayaa sheegay in, habka imtixaanka, ururka macroscopic, iyo halabuurka iyo microstructure imtixaanka ama waxqabadka ama habka, oo dhan ka tirsan yihiin habka baaritaanka burburinta, waayo, qaar ka mid ah foornada culus ee hababka burburinta si buuxda uma qabsan karaan baahida kormeerka tayada, on mid ka mid ah. gacanta, tani waa sababta oo ah ma aha dhaqaalaha, dhanka kale inta badan waa si looga fogaado hal-dhinac ee imtixaanka wax burburinaya. Horumarinta tignoolajiyada NDT waxay siisaa habab aad u horumarsan oo qummanbeen abuurashokormeer tayo leh.
Hababka baaritaanka aan burburin ee been abuurka baarista tayada guud ahaan waa: Habka baaritaanka budada magnetic, habka baaritaanka dhexgalka, habka baaritaanka hadda jira, habka baaritaanka ultrasonic.

Habka baaritaanka walxaha magnetic waxaa si weyn loo isticmaalaa in lagu baaro dusha ama meelaha u dhow cilladaha dusha sare ee birta ferromagnetic ama daawahabeen abuurasho, sida dildilaaca, laalaabyada, dhibco cadcad, ka mid ahaanshaha aan biraha ahayn, delamination, laalaabista, xargaha carbide ama ferritic, iwm. Habkani wuxuu kaliya ku habboon yahay kormeerka ferromagneticbeen abuurasho, laakiin aan loogu talagalay been-abuurka ka samaysan birta austenitic.
Habka kormeerka penetrant kaliya ma hubin karo been-abuurka walxaha magnetic, laakiin sidoo kale wuxuu hubin karaa cilladaha dusha sare ee walxaha aan-ferromagneticbeen abuurasho, sida dildilaaca, dabacsanaanta, laalaabida, iwm. Guud ahaan, waxaa kaliya loo isticmaalaa in lagu hubiyo cilladaha dusha sare ee alaabada aan ferromagnetic ahayn, mana heli karaan cillado qarsoon oo ka hooseeya dusha sare. Tijaabada hadda jirta ee Eddy waxa loo isticmaalaa in lagu hubiyo cilada dusha sare ama meelaha u dhow ee agabka wax-qabadka.
Habka kormeerka Ultrasonic waxaa loo isticmaalaa in lagu hubiyo cilladaha gudaha ee been-abuurka sida godka yaraanshaha, booska cad, dillaaca xudunta u ah, ka mid noqoshada slag, iwm. Inkastoo habkani yahay mid ku habboon, degdeg ah oo dhaqaale, way adag tahay in si sax ah loo go'aamiyo dabeecadda cilladaha.
