Vickers duritia est a vexillum expressing ad duritiam materiae propositus by Britannia Robert L. Smith et George E. Sandland in MCMXXI ad Vickers Ltd. Hoc est alius duritia probatio methodis.
I principle of Vickers duritiem testem:
Vickers duritia testes utitur onus de 49.03 ~ 980.7n ad torcular ad quadratum conice-informibus adamantino intrusus cum includitur angulus CXXXVI ° super superficiem. Post maintaining eam pro certo tempore, metimur incisum obliquus. Lineam longitudinem et ratio Vickers duritia valorem secundum formulam.
2.Load application range:
I: Vickers duritia cum a onus 49.03 ~ 980.7N est idoneam duritiam mensurae maiorum workpieces et altius superficiem layers;
II: Lond Vickers duritia, test onus <1.949.03n, idoneam ad duritiam mensurae tenui workpieces, instrumentum superficiebus aut coatings;
III: Micro-Vickers duritia, test onus <1.961n, idoneam ad duritiam mensurae metallum pullos et valde tenuis superficiem layers.
Praeterea instructa cum knoop indenter, ut possit metimur knoop duritiam fragilis et durum materiae ut vitrum, Ceramics, agate, et artificialis gemstones.
III commoda Vickers duritia testem:
I) et mensuram range est lata, vndique a mollis metalla ad ultra-duritia testers ad Super-dura metalla et mensurae ranges a paucis ad tria milia vogenessitas values.
II) et incisum est parva et non laedas workpiece. Potest adhiberi ad duritiam testis de workpieces quorum superficies non laedi.
III) Propter parva test vis, minimam test vis pervenire 10G, sic potest deprehendere aliquid tenuis et parva workpieces.
4 Disadvantages of the Vickers hardness tester: Compared with Brinell and Rockwell hardness testing methods, the Vickers hardness test has requirements for the smoothness of the workpiece surface, and some workpieces need to be polished, which is time-consuming and labor-intensive; Sustentationem duritiam testem est relative precise et non idoneam ad usum in officinis vel in-site. Est plerumque in laboratorios.
