Musiyano pakati peVickers hardness tester uye microhardness tester

Nekuda kweiyo Vickers kuoma uye microhardness bvunzo, iyo diamond angle yeindenter inoshandiswa kuyerwa yakafanana. Vatengi vanofanira kusarudza sei Vickers kuomarara tester? Nhasi, ini ndichatsanangura muchidimbu musiyano pakati peVickers hardness tester uye microhardness tester.

Kuedza simba saizi division Vickers kuoma uye microhardness tester scale

Vickers hardness tester: bvunzo simba F≥49.03N kana≥HV5

Mutoro mudiki Vickers kuoma: bvunzo simba 1.961N≤F <49.03N kana HV0.2 ~ <HV5

Microhardness tester: bvunzo simba 0.09807N≤F <1.96N kana HV0.01 ~ HV0.2

Saka tinofanira kusarudza sei simba rekuedza rakakodzera?

Tinofanira kutevera musimboti wekuti iyo yakakura indentation, iyo yakanyatsojeka kuyerwa ukoshi kana iyo workpiece mamiriro achibvumira, uye sarudza sezvinodiwa, nekuti iyo diki indentation, yakakura kukanganisa pakuyera kureba kwediagonal, izvo zvinozoita kuti kuwedzera mukukanganisa kwekuoma ukoshi.

Simba rekuyedza reiyo microhardness tester rinowanzo shongedzerwa ne: 0.098N (10gf), 0.245N (25gf), 0.49N (50gf), 0.98N (100gf), 1.96N (200gf), 2.94 (300gf), 4.9gN0), 9. (1000gf) (19.6N (2.0Kgf) zvingasarudzwa)

Iyo magnification inowanzo shongedzerwa ne: zana nguva (kutarisa), 400 nguva (chiyero)

The test force level yeVickers hardness tester inogona kukamurwa kuita: 2.94N (0.3Kgf), 4.9N (0.5Kgf), 9.8N (1.0Kgf), 19.6N (2.0Kgf), 29.4N (3.0Kgf), 49.0N (5.0Kg0), 1. 196N (20Kgf), 294N (30Kgf), 490N (50Kgf) (mienzaniso yakasiyana ine magadzirirwo esimba rekuyedza akasiyana.)

Iyo magnification gadziriso kazhinji: 100 times, 200 times

Iyo Vickers kuomarara tester yeShandong Shancai/Laizhou Laihua Testing Instrument inogona kuita bvunzo dzekuomarara pazvikamu zvakashongedzwa kana nzvimbo dzekubatira.

Zvinoenderana neyakayerwa kuomarara kukosha, mhando yeweld uye metallurgical shanduko inogona kutongwa. Semuenzaniso, kuomarara kwakanyanya kunogona kunge kuri nekuda kwekunyanya kupisa kupinza panguva yewelding, nepo kuderera kwakanyanya kuomarara kungaratidza kusakwana kwewelding kana matambudziko emhando yezvinhu.

Iyo yakagadziriswa Vickers yekuyera sisitimu inomhanyisa yakazara otomatiki bvunzo chirongwa uye kuratidza uye kurekodha zvinoenderana nemhedzisiro.

Kune mhedzisiro yekuyerwa bvunzo, inoenderana graphic report inogona kugadzirwa otomatiki.

Zvakakosha kuziva kuti pakusarudza nzvimbo inomiririra ye.iyo weld seye test point, ita shuwa kuti nzvimbo iyi haina pores, makatsemuka kana zvimwe zvirema zvinogona kukanganisa mhinduro dzebvunzo.

Kana uine chero mibvunzo nezve weld inspection, inzwa wakasununguka kutibata nesu
