Zvishandiso zve carbide zvakafukidzwa zvine zvakanakira zvinotevera:
(1) Kufukidza kwechinhu chiri pamusoro pechinhu ichi kwakaoma zvikuru uye kunodzivirira kupfeka. Kana tichienzanisa necarbide isina simende, carbide yakafukidzwa nesimende inobvumira kushandiswa kwekumhanya kwakanyanya, nokudaro ichivandudza kushanda zvakanaka kwechinhu ichi, kana kuti inogona kuwedzera hupenyu hwechishandiso nekumhanya kumwe chete kwekucheka.
(2) Kukweshana pakati pechinhu chakaputirwa nezvinhu zvakagadziriswa kudiki. Kana tichienzanisa necarbide isina kuputirwa, simba rekucheka recarbide yakaputirwa rakaderedzwa kusvika pamwero wakati, uye kunaka kwenzvimbo yakagadziriswa kuri nani.
(3) Nekuda kwekushanda kwayo kwakazara, banga re carbide rakaputirwa rine hunyanzvi huri nani uye rinogona kushandiswa zvakasiyana-siyana. Nzira inonyanya kushandiswa ye cemented carbide coating ndeye high temperature chemical vapor deposition (HTCVD). Plasma chemical vapor deposition (PCVD) inoshandiswa kuputira pamusoro pe carbide yakaputirwa.
Mhando dzekuputira dzevanocheka carbide yakagadzirwa nesimbi:
Zvinhu zvitatu zvinonyanya kushandiswa pakuputira zvinosanganisira titanium nitride (TiN), titanium carbonitride (TiCN) uye titanium aluminide (TiAIN).
Kuputira titanium nitride kunogona kuwedzera kuomarara uye kuramba kupfeka pamusoro pechishandiso, kuderedza kukweshana, kuderedza kugadzirwa kwemucheto wakavakwa, uye kuwedzera hupenyu hwechishandiso. Zvishandiso zvakaputirwa titanium nitride zvakakodzera kugadzirisa simbi isina alloy yakawanda uye simbi isina ngura.
Pamusoro petitanium carbonitride coating igrey, kuomarara kwayo kwakanyanya kupfuura kwetitanium nitride coating, uye kuramba kupfeka kuri nani. Kana tichienzanisa netitanium nitride coating, titanium carbonitride coating tool inogona kugadziriswa nekukurumidza kukuru uye nekukurumidza kwekucheka (40% ne60% yakakwira kupfuura yetitanium nitride coating, zvichiteerana), uye mwero wekubvisa zvinhu zvebasa wakakwira. Titanium carbonitride coating tools inogona kugadzirisa zvinhu zvakasiyana-siyana zvebasa.
Kuputira titanium aluminide kwacho kwakachena kana kuti kwakasviba. Kunonyanya kuputirwa pamusoro pechigadziko chemidziyo yecarbide yakagadzirwa nesimende. Kunogona kugadziriswa kana tembiricha yekucheka yasvika 800 ℃. Kwakakodzera kucheka kwakaoma nekukurumidza. Panguva yekucheka kwakaoma, machipisi ari munzvimbo yekucheka anogona kubviswa nemhepo yakamanikidzwa. Titanium aluminide yakakodzera kugadzirisa zvinhu zvisina kusimba zvakaita sesimbi yakaoma, titanium alloy, nickel-based alloy, cast iron uye high silicon alloy.
Kushandiswa kwemuchina wekucheka kabhidhidhi wakaiswa simende:
Kufambira mberi kwetekinoroji yekuputira zvishandiso kunoratidzwawo mukushanda kwe nano-coating. Kuputira mazana ezvikamu zvezvinhu zvine ukobvu hwema nanometer akati wandei pachishandiswa chishandiso kunonzi nano-coating. Saizi yechikamu chimwe nechimwe chezvinhu zvekuputira nano idiki kwazvo, saka muganhu wezviyo wakareba kwazvo, une kuomarara kwakanyanya pakupisa. , Simba uye kuomarara kwekutyoka.
Kuomarara kweVickers kwe nano-coating kunogona kusvika HV2800 ～3000, uye kuramba kupfeka kunovandudzwa ne5% ～50% pane kwezvinhu zve micron. Sekureva kwemishumo, parizvino, machira makumi matanhatu nemaviri ezvishandiso zvekuputira zvine machira akasiyana etitanium carbide netitanium carbonitride uye machira mazana mana ezvishandiso zveTiAlN-TiAlN/Al2O3 nano-coated zvakagadzirwa.
Zvichienzaniswa nesimbi dzakaoma dziri pamusoro apa, sulfide (MoS2, WS2) yakafukidzwa nesimbi inomhanya inonzi soft coating, iyo inonyanya kushandiswa kucheka alloys dzealuminium dzine simba guru, titanium alloys nedzimwe simbi dzisingawanzoonekwi.
Kana muchida, ndapota uyai kuzotaura neMSK, tine chido chekupa maturusi ehukuru hwakajairika munguva pfupi uye hurongwa hwezvishandiso zvakagadzirirwa vatengi.
