Ua ntej yuav muas hlau rau coj mus muag los yog industrial purposes, Tuam txhab uas muag yuav tsum paub seb cov hardness ntawm hlau yog. Hardness hais txog yuav ua li cas ib hlau yog thaum nws tawm los resisting yas deformation thiab indentation. Nws kuj hais txog li cas zoo li cas ib hlau yog kom deb li deb uas qhia kuj scratching thiab tej. Muaj ntau txoj kev uas cov hardness ntawm hlau yuav tau ntsuas. Xyuas seb puas muaj ob peb txoj kev kuaj hardness hauv qab no.
Brinell hardness kuaj
Qhov kev kuaj Brinell hardness yog lug txawm ua ib tus thawj hardness kev ntsuam xyuas puas siv. Nws ntsuas cov hardness ntawm ib hlau los thawb ib pob hnyav up against nws ntawm ib tug ceev ceev. Tom qab qhov no yog ua li cas, Ob lub qhov tob thiab cov diameter ntawm lub indentation tshuav qab nyob rau hauv cov hlau yog ntsuas. Qhov no yuav pab illustrate lub hardness ntawm cov hlau.
Rockwell hardness kuaj
Npaum li tus Brinell hardness kuaj, Tus Rockwell hardness kuaj kuj hu rau ib txoj kev kuaj no coj ib tug zoo saib cov diameter ntawm ib indentation tshuav hlau. Qhov kev kuaj no hu rau ib txoj kev kuaj no thov siab rau cov hlau siv xws li ib tug pob zeb diamond cone los yog ib pob hlau pob rau feem ntau. Siab yog thov kom cov hlau ib zaug thiab ces thov dua saib dab tsi nyhuv nws muaj rau cov hlau. Ib tug qauv siv los laij cov hardness ntawm nws raws li tus diameter ntawm tus thib ob indentation.
Vickers hardness kuaj
Tus Vickers hardness kuaj ntawd xub tsim hauv lub UK, Thiab nws tau pom raws li ib lwm txoj rau lub Brinell hardness kuaj. Nws yuav siv ib pyramid indenter maj mam thov quab yuam kom ib hlau saib seb nws reacts. Ib tug qauv uas yuav siv cov hwjchim quab yuam thiab qhov chaw ntawm lub indentation ua nyob rau hauv cov hlau no ces siv los xyuas seb cov hardness ntawm cov hlau.
Hardness yog ib yam ntawm cov yam uas tuam txhab uas muag yuav tsum coj mus ua nyiaj thaum muas hlau. Xyuas seb lwm yam uas tuam txhab uas muag yuav tsum xav txog xeeb rau Eagle Alloys ntawm 800-237-9012 Hnub no. Koj kuj tseem muaj peev xwm ua tau thov ib tsocai Rau tej cov hlau uas peb muaj lub sij hawm no.
