Farqiga u dhexeeya tijaabiyaha adag ee Vickers iyo tijaabiyaha adag ee microhardness

Sababtoo ah tijaabada adkaanta Vickers iyo microhardness, xagasha dheemanka ee indenter-ka loo isticmaalo cabbiraadda waa isku mid. Sidee ayay macaamiishu u dooran karaan tijaabiyaha adkaanta Vickers? Maanta, waxaan si kooban u sharxi doonaa farqiga u dhexeeya tijaabiyaha adkaanta Vickers iyo tijaabiyaha microhardness.

Qaybta cabbirka xoogga tijaabada ah ee adkaanta Vickers iyo cabbirka tijaabada microhardness

Tijaabiyaha adag ee Vickers: xoogga tijaabada F≥49.03N ama≥HV5

Culays yar oo adag oo Vickers ah: xoogga tijaabada 1.961N≤F < 49.03N ama HV0.2 ~ < HV5

Tijaabiyaha Microhardness: xoogga tijaabada 0.09807N≤F < 1.96N ama HV0.01 ~ HV0.2

Haddaba sidee ayaan u dooran karnaa awoodda tijaabada ee ku habboon?

Waa inaan raacnaa mabda'a ah in marka la sii weynaado, qiimaha cabbirka ayaa sax ah haddii xaaladaha shaqada ay oggolaadaan, oo aan dooranno sida loogu baahdo, sababtoo ah marka la sii weynaado, ayaa qaladka lagu cabbiro dhererka geesoodka ah uu sii weynaadaa, taasoo horseedi doonta koror ku yimaada qaladka qiimaha adkaanta.

Xoogga tijaabada ee tijaabiyaha adag ee microhardness guud ahaan waxaa ku qalabaysan: 0.098N (10gf), 0.245N (25gf), 0.49N (50gf), 0.98N (100gf), 1.96N (200gf), 2.94 (300gf), 4.90N (500gf), 9.80N (1000gf) (19.6N (2.0Kgf) ikhtiyaari ah)

Weyneynta guud ahaan waxaa lagu qalabeeyay: 100 jeer (kormeer), 400 jeer (cabbir)

Heerka awoodda tijaabada ee tijaabiyaha adag ee Vickers waxaa loo qaybin karaa: 2.94N (0.3Kgf), 4.9N (0.5Kgf), 9.8N (1.0Kgf), 19.6N (2.0Kgf), 29.4N (3.0Kgf), 49.0N (5.0Kgf), 98.0N (10Kgf), 196N (20Kgf), 294N (30Kgf), 490N (50Kgf) (noocyada kala duwan waxay leeyihiin qaabab awood tijaabo oo kala duwan.)

Qaabeynta weyneynta guud ahaan waa: 100 jeer, 200 jeer

Tijaabiyaha adag ee Vickers ee Shandong Shancai/Laizhou Laihua Testing Instrument wuxuu samayn karaa tijaabooyin adag oo ku saabsan qaybaha alxanka ama meelaha alxanka.

Marka loo eego qiimaha adag ee la cabbiray, tayada alxanka iyo isbeddellada birta ayaa la qiimeyn karaa. Tusaale ahaan, adkaanta aadka u sarreysa waxay sabab u noqon kartaa kulaylka xad-dhaafka ah inta lagu jiro alxanka, halka adkaanta aadka u hooseysa ay muujin karto dhibaatooyin ku filan oo alxanka ama tayada agabka ah.

Nidaamka cabbiraadda Vickers ee la habeeyay wuxuu ku shaqeyn doonaa barnaamij tijaabo ah oo si buuxda otomaatig ah u shaqeeya wuxuuna soo bandhigi doonaa oo duubi doonaa natiijooyinka u dhigma.

Natiijooyinka imtixaanka cabbirka, warbixinta garaafka ee u dhiganta ayaa si toos ah loo soo saari karaa.

Waa muhiim in la ogaado marka la dooranayo aag matal ah oo leh;Alxanka oo ah barta tijaabada, hubi in aaggani uusan lahayn daloolo, dildilaacyo ama cillado kale oo saameyn kara natiijooyinka baaritaanka.

Haddii aad qabtid wax su'aalo ah oo ku saabsan kormeerka alxanka, xor ayaad u tahay inaad nala soo xiriirto
