Nazi izinto zokusebenza ezithunyelwe yikhasimende ukuze kuhlolwe ubulukhuni bokumboza.

Njengoba ubukhulu bokumboza buvame ukuba buncane kakhulu futhi bulinganiswa ngama-micrometer, kunzima ukuthola amanani anembile obulukhuni ngezindlela ezivamile. Ngakho-ke, indlela yokuhlola ubulukhuni be-micro Vickers ivame ukusetshenziswa ekulinganisweni kobulukhuni bokumboza, ngokuvamile ekhonjiswa yi-HV.

Njengoba ungqimba lokumboza luncane kakhulu, ukulinganisa ubulukhuni obuqondile ku-coating kuyinselele. Izinto ezingaphansi komhlaba noma ungqimba olungaphansi luzophazamisa imiphumela yokuhlolwa kobulukhuni. Ngaphambi kokuhlola, silungisa izinto zokusebenza zibe amasampula ajwayelekile bese senza ukuhlolwa kobulukhuni.

I. Inqubo Yokulungiselela Izibonelo

Ukuthatha isampula:Isampula yokumboza isikwa ngomshini wokunyathelisa we-metallographic ukuqinisekisa ukuthi ingxenye evundlile iqukethe ngokuphelele ungqimba lokumboza kanye nezinto eziyisisekelo ze-substrate.

Ukufaka:Sebenzisa umshini wokufaka we-metallographic ukufaka isampula ukuvimbela ukugoba komphetho kanye nokuqhekeka kwe-coating.

Ukugaya Nokupholisha:Gaya isampula isinyathelo ngesinyathelo kusukela ephepheni eliqinile kuya ephepheni elincane, bese ulipholisha nge-metallographicukugayaumshini wokupholisha kuze kube yilapho ingxenye evundlile ingenawo umklwebhe, umngcele phakathi kwesembozo kanye nesisekelo ucacile, futhi akukho ungqimba olukhubazekile olusele.

II.Inqubo Yokuhlola Ubulukhuni

Samukela isihloli sokuqina kwe-Vickers esingezansi esifakwe uhlelo lokulinganisa oluzenzakalelayo lokuhlola.

Beka isampula elungisiwe kancane kancane etafuleni lokusebenza lesihloli sokuqina bese ingxenye yengubo ibheke phezulu. Lungisa isampula ngobumnene ngebhlokhi yokucindezela ukuqinisekisa ukuthi ayishukunyiswa futhi ayithambeki.

III.Inqubo Yokuhlola

Ukugxila Kwesandla (Ongakukhetha kuModeli Yokugxila Okuzenzakalelayo)

Lungisa ngesandla ukugxila kwethuluzi ukuze kuboniswe ngokucacile ukuthungwa kwendawo yokusebenza ku-interface yekhompyutha.

Qala Ukulinganisa

Setha indlela yokulinganisa kukhompyutha bese uchofoza okuthi Qala ukuze uqale inqubo yokuhlola.

Ukulayisha Okuzenzakalelayo Kokugoba

Ithuluzi lisebenzisa ngokuzenzakalelayo amandla okuhlola asethi → ukubamba okuhlala → ukukhulula, bese lakha ukugoba kwe-Vickers okufana nedayimane.

Ukulinganisa Ukugoba Okuzenzakalelayo

Ilensi ibona ngokuzenzakalelayo ubude obuqondile bokugoba, futhi uhlelo lubala ngokuzenzakalelayo inani le-Vickers hardness HV.

Ukubalwa Kobukhulu Bokumboza

Nquma indawo yokuxhumana phakathi kwengubo kanye ne-substrate, bese isofthiwe ibala ngokuzenzakalelayo.

Uma unentshisekelo kulezi zixhobo zokulungiselela amasampula kanye nokuhlolwa kobulukhuni be-micro Vickers, sicela ubheke uhlu lwemikhiqizo futhi uzizwe ukhululekile ukuxhumana nathi ukuze ufunde kabanzi ngayo.
