Sababtoo ah adkaanshaha Vickers iyo tijaabinta microhardness, xagasha dheemanka ee galiyaha loo isticmaalo cabbirka waa isku mid. Sidee macaamiishu u dooran karaan tijaabiyaha adkaanta Vickers? Maanta, waxaan si kooban u qeexi doonaa farqiga u dhexeeya tijaabiyaha adkaanta Vickers iyo tijaabiyaha microhardness.
Tijaabi qaybta cabbirka xoogga ee Vickers engegnaanta iyo cabbirka tijaabiyaha mikrohardness
Tijaabada adag ee Vickers: Tijaabada xoogga F≥49.03N ama≥HV5
Culays yar oo Vickers adag: xoogga tijaabada 1.961N≤F <49.03N ama HV0.2 ~ <HV5
Tijaabada Microhardness: xoogga tijaabada 0.09807N≤F <1.96N ama HV0.01 ~ HV0.2
Haddaba sidee baannu u dooranaa xoogga imtixaanka ku habboon?
Waa in aan raacnaa mabda'a ah in ka weyn ee gelinta, inta badan saxda ah qiimaha cabbirka haddii shuruudaha workpiece ay oggolaadaan, oo ay doortaan sida loo baahan yahay, sababtoo ah ka yar gelinta, qalad weyn ee cabbiraadda dhererka dhinaca, taas oo u horseedi doonta kororka qaladka qiimaha engegnaanta.
Xoogga tijaabada ee tijaabiyaha microhardness waxaa guud ahaan lagu qalabeeyay: 0.098N (10gf), 0.245N (25gf), 0.49N (50gf), 0.98N (100gf), 1.96N (200gf), 2.94 (300gf), 4.90N (300gf), 4.90N (1000gf) (19.6N (2.0Kgf) ikhtiyaar)
Weyneynta guud ahaan waxaa lagu qalabeeyay: 100 jeer (fiirin), 400 jeer (cabir)
Heerka xoogga tijaabada ee tijaabiyaha qallafsanaanta Vickers waxa 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 (0.0Kg.) 196N (20Kgf), 294N (30Kgf), 490N (50Kgf)
Qaabeynta weyneynta guud ahaan waa: 100 jeer, 200 jeer
Tijaabada qallafsanaanta Vickers ee Shandong Shancai/Laizhou Laihua Qalabka Tijaabada wuxuu samayn karaa tijaabooyin adag qaybaha alxanka ama meelaha alxanka.
Marka loo eego qiimaha qallafsanaanta la cabbiray, tayada alxanka iyo isbeddellada biraha waa la qiimeyn karaa. Tusaale ahaan, adkaanta aadka u sareysa waxaa laga yaabaa inay sabab u tahay kuleyl xad dhaaf ah oo la geliyay inta lagu jiro alxanka, halka adkaanta aadka u yar ay muujin karto alxanka ku filan ama dhibaatooyinka tayada alaabta.
Nidaamka cabbiraadda ee loo habeeyay ee Vickers waxa uu socodsiin doonaa barnaamij tijaabo ah oo toos ah oo toos ah oo soo bandhigi doona oo diiwaangelin doona natiijooyinka u dhigma.
Natiijooyinka tijaabada cabbiraadda, warbixinta garaafka u dhigma si toos ah ayaa loo soo saari karaa.
Waxaa muhiim ah in la ogaado marka la dooranayo aagga wakiil ee;alxanka sida barta tijaabada, hubi in aaggani aanu lahayn dalool, dildilaac ama cillado kale oo saamayn kara natiijada baaritaanka.
Haddii aad qabtid wax su'aalo ah oo ku saabsan kormeerka alxanka, xor ayaad u tahay inaad nala soo xiriirto
