1. Pfungwa yedhaimondi pamusoro pekuvhara
Diamond surface coating, inoreva kushandiswa kwepamusoro pekurapa tekinoroji panzvimbo yedhaimani yakavharwa nerumwe rwezvimwe zvinhu firimu. Sechinhu chekuputira, kazhinji simbi (kusanganisira chiwanikwa), semhangura, nickel, titanium, molybdenum, mhangura tin titanium alloy, nickel cobalt alloy, nickel cobalt phosphorus alloy, nezvimwewo; Coating material zvakare zvimwe zvisiri-metallic materials, zvakaita seceramics, titanium carbide, titanium ammonia uye mamwe macommunication anoomesa zvinhu zvakaomarara. Kana iyo yekupfeka iri simbi, inogona zvakare kunzi diamondi pamusoro pesimbi.
Chinangwa chekuputira pamusoro ndechekupa madhaimani masisitimu ane akakosha emuviri uye emakemikari zvimiro, kuitira kuti avandudze mashandisiro azvo. Semuenzaniso, kushandiswa kwepamusoro-yakavharidzirwa diamond abrasive kugadzira resin grinding vhiri, hupenyu hwayo hwebasa hunowedzerwa zvakanyanya.
2. Kurongwa kwepamusoro pekuvhara nzira
Indasitiri yepamusoro yekurapa nzira yekupatsanurwa ona nhamba iri pazasi, iyo yakanyatso shandiswa mune yakanyanya kuoma abrasive pamusoro pekuisa nzira, inonyanya kufarirwa inonyanya kunyorova kemikemikari plating (hapana electrolysis plating) uye plating, yakaoma plating (inozivikanwawo sevacuum plating) mumakemikari vapor deposition (CVD) uye yemuviri mhute deposition (PVD), kusanganisira ine vacuum liquid poda sinter simbi.
3. Plating ukobvu inomiririra nzira
Nekuti ukobvu hwehuputi hwepamusoro pedhaimondi abrasive particles zvakaoma kuona zvakananga, inowanzo ratidzwa sehuremu hwekuwedzera (%). Pane nzira mbiri dzekumiririra kuwedzera uremu:
Iko A ndiko kuwedzera kwehuremu (%); G1 ndiko kukuya kurema kusati kwaputirwa; G2 ndiyo uremu hwekuputira; G ndiyo huremu hwese (G=G1 + G2)
4. Mhedzisiro yedhaimondi pamusoro pekuisa padhaimani chishandiso kuita
Mumudziyo wedhaimondi wakagadzirwa neFe, Cu, Co uye Ni, zvidimbu zvedhaimondi zvinongokwanisa kuiswa mukati memujenya unosunga matrix nekuda kwekusabatana kwekemikari kweiyo inosunga iri pamusoro uye kushomeka kwekupinda mukati. Pasi pekuita kwesimba rekukuya, kana dhaimondi rekukuya chidimbu chaiswa pachikamu chepamusoro, tireyi yesimbi yemuviri inorasikirwa nedhaimondi zvidimbu uye inodonha yega, izvo zvinoderedza hupenyu hwesevhisi uye kushanda zvakanaka kwemidziyo yedhaimondi, uye kukuya kwedhaimondi hakugone kuridzwa zvizere. Naizvozvo, iyo yedhaimondi ine hunhu hwemetallization, iyo inogona kunyatso kuvandudza hupenyu hwesevhisi uye kugadzirisa kushanda kwemidziyo yedhaimondi. Chinhu chayo ndechekugadzira zvinhu zvekubatanidza zvakaita seTi kana alloy yayo yakanamirwa pamusoro pedhaimani, kuburikidza nekupisa nekudziya kurapwa, kuitira kuti dhaimondi rigadzire yunifomu yemakemikari bonding layer.
Nekupfekedza zvidimbu zvemadhaimondi, kuita kwekunamira nedhaimani kuita simbi yedhaimondi. Kune rimwe divi, iyo simbi yedhaimani pamusoro uye simbi muviri inosunga mumiriri pakati pesimbi metallurgical musanganiswa, saka, kuvhara kurapwa kwedhaimani kune inotonhora yekumanikidza mvura sintering uye inopisa yakasimba nhanho sintering ine hupamhi hwekushanda, saka tayi remuviri alloy yedhaimani kukuya zviyo kubatanidzwa kwakawedzera, kuderedza mudziyo wedhaimondi mukushandiswa kwekukuya, kuvandudza hupenyu hwebasa uye kugona kwedhaimani maturusi.
5. Ndeapi mabasa makuru ekurapwa kwedhaimani?
1. Kuvandudza kugona kwemuviri we "fetus" kuisa diamondi.
Nekuda kwekuwedzera kwekupisa uye kutonhora kuderera, kushushikana kwakanyanya kwemafuta kunogadzirwa munzvimbo yekubatanidza pakati pedhaimani nemuviri wetire, izvo zvinozoita kuti dhaimondi nere fetal body yekubata bhandi ribudise mitsara midiki, nekudaro ichidzikisa kugona kwemuviri wetayi wakaputirwa nedhaimani. Yedhaimondi pamusoro pekuputira inogona kuvandudza chimiro chemuviri uye chemakemikari zvimiro zvedhaimondi uye yemuviri interface, kuburikidza neiyo simba spectrum ongororo, yakasimbisa kuti simbi carbide kuumbwa mufirimu kubva mukati kuenda kunze zvishoma nezvishoma inoshanduka kuenda kuzvinhu zvesimbi, inonzi MeC-Me firimu, diamondi pamusoro uye firimu ikemikari chisungo, musanganiswa uyu chete unogona kuvandudza kugona kwedhaimondi, kana kuvandudza kugona kwemuviri wedhaimondi. Izvi zvinoreva kuti, kupfekedza kunoshanda sebhiriji rinosunga pakati pezviviri.
2. Kuvandudza simba redhaimani.
Nekuti makristasi edhaimani anowanzo aine hurema hwemukati, senge microcracks, madiki cavities, nezvimwewo, izvi zvakakanganisika zvemukati mumakristasi zvinobhadharwa nekuzadza iyo MeC-Me membrane. Plating inoita basa rekusimbisa uye kuomesa. Chemical plating uye plating inogona kuvandudza kusimba kwezvishoma, zvepakati uye zvakakwirira zvigadzirwa.
3. Deredza kupisa kwekushisa.
Iyo simbi inonamira inononoka kupfuura iyo yedhaimani abrasive. Iko kupisa kwekukuya kunopfuudzwa kune resin inosunga mumiririri pakusangana nechikamu chekukuya, kuitira kuti zvipiswe kubva pakarepo kupisa kwekushisa kwepamusoro, kuitira kuchengetedza simba rayo rekubata padhaimondi rinoputika.
4. Kuzviparadzanisa nevamwe uye kudzivirira.
Munguva yekupisa kwekushisa kwepamusoro uye kukuya pakupisa kwepamusoro, jira rekuputira rinoparadzanisa uye rinodzivirira dhaimondi kudzivirira graphitization, oxidation kana kumwe kuchinja kwemakemikari.
