Video ma'auni Vicker Hardness Gauge Overview

Bidiyo ma'auni Vicker hardness mita ne a kan daban-daban jerin Vicker hardness mita, ta hanyar CCD launi kamara dubawa, kai tsaye a kan nuni iya auna kammala. Ƙara saurin gwaji da sassauci, inganta daidaito na ma'auni, nuna haske na ingancin hoto, rage kuskuren aiki na mutum na tsarin taƙawa, yana iya biyan buƙatun gwajin taurin microscopy daban-daban.

　　Vicker Hardness Kuskuren Bincike
1, lu'u-ulu'u madaidaicin mutum biyu gaba-gaba clamping kusurwa karkatarwa daga misali darajar haifar da tauri ma'auni kusurwa alpha ne babban, tauri ma'auni darajar fiye da tauri ainihi darajar kasa. JJG334-1993 "Lu'u-lu'u'u'u'u'u'u'u'u'u'u'u'u'u'u'u'u'u'u'u'u'u'u'u'u'u'u'u'u'u'u'u'u'u'u'u'u'u'u'u'u'u'u'u'u' Ƙananan kaya da kuma microscopic Vickers press kai ya kamata ya zama 136 ± 0.25 °.
2, matsawa kai crossedges haifar da tauri ma'auni kuskure, saboda matsawa kai da crossedges, stamping juya a rectangle, sa ma'auni stamping diagonal tsawon kara, tauri darajar rage, kawo mummunan tauri ma'auni kuskure. A cikin kewayon gwajin tauri na microscopy, tasirin matsawa na mutum yana da girma sosai. JJG334-1993 "Lu'u-lu'u-u-u-u-u-u-u-u-u-u-u-u-u-u-u-u-u-u-u-u-u-u-u-u-u-u-u-u-u-u-u-u-u-u-u-u-u-u-u-u-u-u-u-u-u-u-u-u-u-u-u
3, daban-daban samfurin kayan haifar da tauri ma'auni kuskure, gwajin sakamakon ya nuna cewa daban-daban kayan crushing siffofin daban-daban, a kan crushing diagonal gaskiya karshen hukunci haifar da matsala, saboda haka kawo tauri ma'auni kuskure.
4, samfurin surface roughness ba ya dace da ƙa'idodi haifar da tauri ma'auni kuskure, da samfurin surface roughness karami, crushing gefen mafi bayyane, to, crushing diagonal tsawon ma'auni mafi m, don haka za a iya samun mafi daidai, m tauri darajar.
5, samfurin siffar ba ya dace da ƙa'idodi haifar da tauri auna kuskure, samfurin kauri rage zuwa wani mataki, zai sa tauri darajar rage. Lokacin da samfurin farfajiyar ba sama ba ne, darajar tauri tana canzawa tare da canjin diamita na samfurin farfajiyar. GB / T4340.1-1999 "Karfe Vicker tauri gwajin Sashe na 1: gwajin hanyar" ya bayyana: samfurin ko gwajin layi kauri ya kamata ya kasance akalla 1.5 sau da shekaru na bango diagonal tsawon, bayan gwajin samfurin baya ya kamata ba a bayyana ganewa karkatarwa alamu; Don sakamakon gwajin a kan samfurin karkata, ya kamata a gyara ta amfani da teburin gyara; Don samfurin da ke da ƙananan sassan ko siffar da ba daidai ba, samfurin za a iya sanya shi ko gwajin shi ta amfani da takardar tallafi ta musamman.
6, tsakanin crushing da kuma crushing zuwa samfurin gefen nesa ba ya dace da bukatun da tauri ma'auni kuskure, da kuma crushing tsakanin nesa da yawa kusa, zai sa tauri darajar haɓaka; Rashin nesa tsakanin crushing zuwa samfurin gefen zai sa tauri darajar rage. GB / T4340.1-1999 "Karfe Vicker tauri gwajin Sashe na 1: gwajin hanyar" ya bayyana: kowane stamping tsakiya daga samfurin gefen nesa, ga karfe, jan kafe da kuma jan kafe ya kamata a kalla 2.5 sau na stamping diagonal tsawon, ga haske karfe, gubar, tin da kuma kuma gwajin ya kamata a kalla 3 sau na stamping diagonal tsawon; A nesa tsakanin biyu makwabta stamping cibiyoyin, ga karfe, jan ƙarfe da kuma jan ƙarfe ya kamata a kalla sau 3 na stamping diagonal tsawon, ga haske karfe, gubar, tin da kuma gami ya kamata a kalla sau 6 na stamping diagonal tsawon, idan biyu makwabta stamping girman daban-daban, ya kamata a ƙayyade stamping spacing da babban stamping.
　　Shin Vicker Hardness Gauge zai iya auna nitrogen sassa?
Shin za a iya amfani da Vicker Hardness Gauge don auna nitrogen? Yawancin injiniyoyi sun yi imanin cewa saboda nitrogen surface yana da wani hardening layer, kuma Vicker tauri lissafi ne bounce hanyar, nitrogen gaskiya tauri ne da wuya a nuna, don haka gabaɗaya Vicker tauri ba ya dace da nitrogen ma'auni.
Viktor tauri ma'auni ne kawai a cikin gaba daya ba tare da hanyar da za a yi amfani da su don auna nitrogen sassa, amma Viktor tauri ma'auni bayanai kawai a matsayin wani m yanayi ba zai iya zama misali ma'auni bayanai, a matsayin karshe ma'auni bayanai ko a matsayin madaidaicin, ciki har da tsari, tauri da kuma m matakin da dai sauransu.
