Musiyano uripo pakati peVickers hardness tester nemicrohardness tester

Nekuda kwekuyedzwa kweVickers hardness uye microhardness, kona yedhaimani ye indenter inoshandiswa pakuyera yakafanana. Vatengi vanofanira kusarudza sei Vickers hardness tester? Nhasi, ndichatsanangura muchidimbu musiyano uripo pakati peVickers hardness tester nemicrohardness tester.

Kupatsanura saizi yesimba rekuyedza Vickers kuomarara uye microhardness tester scale

Muedzisi wekuomarara weVickers: simba rekuyedza F≥49.03N kana≥HV5

Kuomarara kweVickers mutoro mudiki: simba rekuyedza 1.961N≤F < 49.03N kana HV0.2 ~ < HV5

Muedzi weMicrohardness: simba rekuyedza 0.09807N≤F < 1.96N kana HV0.01 ~ HV0.2

Saka tinofanira kusarudza sei simba rekuyedza rakakodzera?

Tinofanira kutevedzera musimboti wekuti kana gomba rikakura, kukosha kwekuyera kwacho kwakanyatsojeka kana mamiriro ebasa achibvumira, uye sarudza sezvinodiwa, nekuti kana gomba rikakura, kukanganisa kukuru pakuyera kureba kwedivi, izvo zvinotungamira mukuwedzera kwekukanganisa kwekuomarara.

Simba rekuyedza remuyedzo we microhardness rinowanzo kuve ne: 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) sarudzo)

Kukwidziridzwa kwacho kunowanzo shongedzerwa ne: ka100 (kutarisa), ka400 (kuyerwa)

Simba rekuyedza reVickers hardness tester rinogona kukamurwa kuita: 2.94N (0.3Kgf), 4.9N (0.5Kgf), 9.8N (1.0Kgf), 19.6N (2.0Kgf), 29.4N (3.0Kgf), 49.0N (5.0Kgf), 98.0N (10Kgf), 196N (20Kgf), 294N (30Kgf), 490N (50Kgf) (mhando dzakasiyana dzine marongero akasiyana esimba rekuyedza.)

Magadzirirwo ekuwedzera anowanzo kuve: ka100, ka200

Muchina wekuyedza kuomarara weVickers weShandong Shancai/Laizhou Laihua Testing Instrument unogona kuita bvunzo dzekuomarara pazvikamu zvakasungirirwa kana nzvimbo dzekuwedera.

Zvichienderana nekuomarara kwakayerwa, mhando yekuchinja kweweld uye metallurgical inogona kutongwa. Semuenzaniso, kuomarara kwakanyanya kunogona kukonzerwa nekupisa kwakanyanya panguva yekuwelda, nepo kuomarara kwakaderera kunogona kuratidza kusakwana kwewelding kana matambudziko emhando yezvinhu.

Sisitimu yekuyera yeVickers yakagadzirirwa ichaita chirongwa chekuyedza otomatiki uye icharatidza uye ichanyora mhedzisiro inoenderana.

Pamhedzisiro yebvunzo yekuyera, mushumo wemifananidzo unoenderana nawo unogona kugadzirwa otomatiki.

Zvakakosha kucherechedza kuti pakusarudza nzvimbo inomiririra.Kana wave weld senzvimbo yekuyedza, iva nechokwadi chekuti nzvimbo iyi haina maburi, mitswe kana zvimwe zvikanganiso zvinogona kukanganisa mhedzisiro yebvunzo.

Kana muine mibvunzo nezvekuongorora weld, musazeza kutibata nesu
