Kuedzwa kweKuoma kweCore neMicro Vickers Hardness Tester

Mumaitiro ekusimbisa pamusoro pesimbi akadai se carburizing, nitriding uye induction quenching, kuyedzwa kwekuomarara kwemukati uye kudzika kwechikamu chakaomeswa, pamwe nekukanganisika mumaitiro ekupisa, zvinokanganisa hunhu hwese hwezvigadzirwa. Tinoshandisa micro Vickers hardness tester kuti tipedzise maitiro ese ekuyedza uye kudzora kudzika kwechikamu chakaomeswa, chiratidzo chikuru chekudzora hunhu.

1. Kugadzirira Muenzaniso

· Sarudza chikamu chekuyedza kana sampuro yakajairika wocheka chikamu chemuchinjikwa kuti uve nechokwadi chekuti pamusoro pebvunzo pakamira zvakanaka, hapana kuchinja uye hapana kuputika.

· Gaya uye pukuta chikamu chemuchinjiko kuti ubvise ganda repamusoro re oxide uye mavanga ekugadzira.

· Cheka sezvinodiwa nemitemo yakakodzera (kana zvichidikanwa) kuti unyatsosiyanisa chikamu chepamusoro nechimiro chepakati.

2.Kuedza Kuoma Kwepfungwa

Tinoshandisa Model MHV-1000AT micro Vickers hardness tester kuti tipedzise maitiro ese ekuyedza.

· Isa sampuro yacho zvakachengeteka pachikuva cheMicro Vickers hardness tester woiisa panzvimbo yepakati (kure nepamusoro peganda rakaomeswa).

· Isa simba rekuyedza (rinowanzoitwa HV1.0) uye nguva yekugara, uye simbisa kuti michina yacho yakaongororwa nemazvo.

· Sarudza nzvimbo dzekuyera dzakaenzana nhatu kusvika kushanu pakati pechinhu, uchidzivirira zvikanganiso zvakaita sekunge maburi, maburi emhepo uye zvinosanganisirwa.

· Tanga kuyera; kukosha kwekuoma kunoverengwa otomatiki, uye kukosha kwepakati kunotorwa semhedzisiro yekupedzisira yekuoma kwepakati.

3. Kuedzwa kweKudzika kweLayer Yakaoma

· Ronga nzvimbo dzekuyedza panguva dzakaenzana nemutsetse wakatwasuka kubva pamusoro kusvika pakati, uye isa daro renhanho zvichienderana nezvinodiwa (zvinowanzova 10–50 μm).

· Yera poindi yekuomarara nepoindi, uye nyora kukosha kwekuomarara uye kudzika kwakakodzera kwenzvimbo yega yega.

· Ramba uchiyera kusvika kuomarara kwadzikama pasi pekukosha kwakakosha, wobva wamisa bvunzo.

4. Kutongwa kweKudzika kweLayer Rakaomeswa Zvakanyanya (CHD)

· Sarudza kukosha kwekuomarara kwakakosha zvichienderana nezvinodiwa (semuenzaniso, GB/T 9450).

· Tsvaga nzvimbo iyo kuomarara kunotanga kuderera kusvika pakuva kukosha kwakakosha; kudzika uku kunotsanangurwa sekudzika kwechikamu chakasimba chinoshanda.

5. Kugadziriswa kweData uye Kushuma

· Ronga curve yekugoverwa kwehukukutu nehupamhi hwakaita sehorizontal axis uye kuomarara sehorizontal axis kuratidza gradient yekuomarara.

· Ronga data rinosanganisira kuomarara kwepakati, kudzika kwechikamu chakaomarara uye curve yekuomarara kuti ugadzire mushumo wekuyedza.

Kuyedzwa kwekuomarara uye kudzika kwepamusoro kunoitwa ne

Muchina wekucheka metallographic weQ-80Z

Muchina wekukuya nekupukuta weMP-2000 otomatiki

Muedzo wekuomarara kweMHV-1000AT micro Vickers

Kana uchida kuziva zvakawanda nezvavo ndapota tinya zvinoenderana nechinhu chechigadzirwa.
