Coated carbide zvishandiso zvine zvinotevera zvakanakira:
(1) Iyo yekupfekedza zvinhu zveyepamusoro layer ine yakanyanya kuomarara uye kupfeka kuramba.Kuenzaniswa neiyo isina kuvharwa simende carbide, iyo yakavharwa simende carbide inobvumira kushandiswa kwepamusoro kucheka kumhanya, nekudaro kunatsiridza mashandiro ekugadzirisa, kana Inogona kuwedzera zvakanyanya hupenyu hwechishandiso panguva imwechete yekucheka.
(2) Iyo coefficient of friction pakati pezvakaputirwa zvinhu uye zvakagadziriswa zvinhu zvidiki.Kuenzaniswa neiyo isina kuvharwa cemented carbide, simba rekucheka reiyo yakavharwa simende carbide inoderedzwa kusvika kune imwe nhanho, uye iyo yakagadziridzwa yemhando yepamusoro iri nani.
(3) Nekuda kwekuita kwakanaka kwakazara, iyo yakavharwa carbide banga ine zvirinani kuita zvakasiyana uye yakakura application renji.Nzira inonyanya kushandiswa yekuisa simende ye carbide coating ndeye tembiricha yemakemikari vapor deposition (HTCVD).Plasma kemikari vapor deposition (PCVD) inoshandiswa kupfeka pamusoro pecemented carbide.
Coating marudzi ecemented carbide milling cutters:
Zvinhu zvitatu zvinowanzojairika zvekupfekedza titanium nitride (TiN), titanium carbonitride (TiCN) uye titanium aluminide (TiAIN).
Titanium nitride coating inogona kuwedzera kuoma uye kupfeka kuramba kwechishandiso chepamusoro, kuderedza friction coefficient, kuderedza chizvarwa cheyakavakwa-mupendero, uye kuwedzera hupenyu hwechishandiso.Titanium nitride yakavharidzirwa maturusi akakodzera kugadzirisa yakaderera-alloy simbi uye Stainless simbi.
Pamusoro pe titanium carbonitride coating i grey, kuoma kwakakwirira kudarika iyo yetitanium nitride coating, uye kupfeka kuramba kuri nani.Kuenzaniswa netitanium nitride coating, titanium carbonitride coating tool inogona kugadziriswa nekumhanya kukuru kwekudya uye kucheka kumhanya (40% uye 60% yakakwirira kupfuura iyo titanium nitride coating, zvichiteerana), uye chiyero chekubvisa zvinhu chakakwira.Titanium carbonitride yakavharwa maturusi anogona kugadzira akasiyana ezvigadzirwa zvebasa.
Iyo titanium aluminide yekuputira igrey kana dema.Iyo inonyanya kuputirwa pamusoro peiyo simende carbide chishandiso base.Inogona kugadziridzwa kana tembiricha yekucheka yasvika 800 ℃.Inokodzera kuchekwa kwepamusoro kwakaoma.Munguva yekucheka kwakaoma, machipisi munzvimbo yekucheka anogona kubviswa nemhepo yakamanikidzwa.Titanium aluminide inokodzera kugadzirisa zvinhu zvisina kusimba senge simbi yakaoma, titanium alloy, nickel-based alloy, cast iron uye yakakwira silicon aluminium alloy.
Coating application yecemented carbide milling cutter:
Kufambira mberi kweiyo tekinoroji yekuputira tekinoroji inoratidzwa zvakare mukuita kwenano-coating.Kupfekedza mazana ematuru ezvishandiso nehukobvu hwema nanometer akati wandei pane iyo base base material inonzi nano-coating.Ukuru hwechikamu chimwe nechimwe che nano-coating material iduku zvikuru, saka muganhu wezviyo wakareba kwazvo, une hutsika hwepamusoro-soro., Simba uye kutsemuka kuoma.
Iyo Vickers kuomarara kwenano-coating inogona kusvika HV2800 ~ 3000, uye kupfeka kuramba kunovandudzwa ne5% ~ 50% pane iyo yemicron zvinhu.Sekureva kwemishumo, pari zvino, 62 akaturikidzana ezvokupfekedza maturusi ane alternating coatings etitanium carbide uye titanium carbonitride uye mazana mana ezvikamu zveTiAlN-TiAlN/Al2O3 nano-coated maturusi akagadzirwa.
Kana ichienzaniswa nepamusoro-soro mabhanhire akaoma, sulfide (MoS2, WS2) yakavharwa pasimbi inomhanya inonzi soft coating, iyo inonyanya kushandiswa kucheka yakakwirira-simba aruminiyamu alloys, titanium alloys uye dzimwe simbi dzisingawanzoitiki.
Kana iwe uine chero chaunoda, ndapota huya kunobata MSK, isu tine hunyoro kupa zvakajairwa saizi maturusi munguva pfupi uye akagadziridzwa maturusi kuronga kune vatengi.
