Iyo yakavharwa saha blade inowanikwa nekupfekedza chidimbu chitete chesimbi chinodzikisira nekupfeka kwakanaka kusamira pamusoro peiyo high-speed simbi (HSS) substrate ine simba rakanaka uye kusimba nemhute deposition nzira. Sechivharo chekupisa uye chivharo chemakemikari, iko kupfekedza kunoderedza kupararira kwekupisa uye kuita kwemakemikari pakati pesaha uye chidimbu chebasa. Iine kuoma kwepamusoro pepamusoro, kumira kwakanaka kwekupfeka, kugadzikana kwemakemikari zvivakwa, kupisa kupisa uye oxidation kuramba, diki friction coefficient uye thermal conductivity. Yakadzika-level maitiro, hupenyu hwesaha blade hunogona kuwedzerwa kakawanda kana ichienzaniswa neiyo isina kuvharwa saha blade panguva yekucheka. Nokudaro, iyo yakavharidzirwa saha blade yave chiratidzo chemazuva ano ekucheka masaha mashizha.

Yakazara high-speed simbi saw blade, ruvara ichena simbi ruvara, ibasa resaha pasina coating kurapwa, kucheka general non-ferrous simbi, akadai ndarira, aruminiyamu uye zvichingodaro.

Nitriding coating (dema) VAPO nitriding coating yakakwira tembiricha oxidation kupisa kurapwa, ruvara rwakasviba dema, mushure memakemikari element Fe3O4 inoiswa chaiyo chaiyo yekupisa kurapwa, iyo oxide layer (Fe3O4) inoumbwa pamusoro, uye ukobvu hweiyo. oxide layer inosvika 5-10 Micron, kuoma kwepasi kunosvika 800-900HV, friction coefficient: 0.65, rudzi urwu rwesaha rune kutsvedzerera kwepamusoro, izvo zvinobatsira kusimudzira kugona kuzvizora kwesaha, uye chiitiko. kuti blade yesaha yakanamatira nezvinhu inogona kudziviswa kusvika pamwero wakati. Zvekucheka general zvinhu. Nekuda kwehunyanzvi hwekugadzira tekinoroji uye kudhura kwekuita, chigadzirwa chinoshandiswa zvakanyanya mumusika.

Titanium nitride coating (yegoridhe) TIN Mushure mePVD nitrogen titanium kurapwa, ukobvu hwemasaha blade coating inenge 2-4 microns, kuomarara kwayo kuri kuita 2200-2400HV, friction coefficient: 0.55, tembiricha yekucheka: 520°C, iyi yakaona saw blade inogona kuwedzera zvakanyanya nguva yebasa yesaha. Kuti ishandise zvizere maitiro ayo, kukurumidza kwekucheka kunofanira kuwedzerwa kuratidza kukosha kwayo. Basa guru rekuputira uku nderekuita kuti blade yesaha irambe yakasimba nekucheka. Nokuda kwekucheka kwezvinhu zvakajairika, kushanda kwayo kwakanakisisa kunogona kuwedzera kukurumidza kwekucheka uye kuderedza kurasikirwa.

Chromium Nitride Coating (Super Coating for short) CrN Uku kupfekedza kunonyanya kushingirira kunamatira, ngura uye oxidation. Ukobvu hwekuputira hwesaha blade ndeye 2-4 microns, kuomarara kwepasi: 1800HV, tembiricha yekucheka yakaderera pane 700 ° C, uye ruvara isimbi grey. Yakanyanya kukurudzirwa kucheka mhangura uye titanium, iyo yekubikira haina kukanganisa nharaunda. Inokodzera kucheka mhangura, aluminium uye zvimwe zvinhu, ine yakakwira coating density uye kuoma kwepasi, uye yakaderera friction factor pakati pemachira ese.

Titanium aruminiyamu nitride coating (ruvara) TIALN Iyi itsva yakawanda-layer anti-wear coating. Iyo saha blade yakabatwa neakawanda-layer PVD coating yawana yakaderera kwazvo friction coefficient. Kuoma kwayo kwepamusoro kunosvika 3000-3300HV. friction coefficient: 0.35, oxidation tembiricha: 450 ° C, rudzi urwu rwesaha blade rinogona kuita kuti nzvimbo yekucheka inyatso kupfava, uye blade yesaha inonyanya kusakara. Inokurudzirwa kucheka zvinhu zvine kukurumidza kucheka uye kumhanya kwekudya uye kucheka kusimba kwesimba kunodarika 800 N/mm2, seStainless simbi, nezvimwewo, inoshandiswa pasi pemamiriro ekushanda akaomarara.

Aluminium titanium nitride coating (inonzi super A coating) ALTIN ​​Iyi itsva yakawanda-layer composite anti-wear coating, ukobvu hweiyi jasi i2-4 microns, kuoma kwepasi: 3500HV, friction coefficient: 0.4, iyo tembiricha yekucheka Pazasi 900 ° C, zvinokurudzirwa kushandisa zvinhu zvine kukurumidza kucheka uye kumhanya kwekudya uye kucheka kusimba kwesimba rinopfuura 800 N/mm2 (sesimbi isina tsvina), uye kuishandisa mumamiriro ekushanda akaomarara.zvakadai sekucheka kwakaoma. Nekuda kwekuoma uye kugadzikana kwakanaka kwealuminium titanium nitride yakazviputira pachayo, blade yesaha inonyanya kusaga uye yakakodzera kucheka zvese zvesimbi. Nekuda kweiyo yakaderera friction coefficient uye yakaderera thermal conductivity, inonyanya kukodzera kucheka kwakaoma pakumhanya uye kupisa kwakanyanya.

Titanium Carbonitride Coating (Bronze) TICN Iri coating rakakodzera kune zvakanyanya kuomesa anti-kupfeka zvinodiwa. Inokurudzirwa kucheka zvinhu zvine simba rekusimudzira pamusoro pe800 N/mm2. Ukobvu hwekuputira ndeye 3 microns, iyo coefficient yekukweshana: 0.45, oxidation tembiricha: 875 ° C, uye kuoma kwepasi kunosvika 3300-3500HV. Haisi chete yakakodzera kutema simbi ine simba rakawanda sesimbi isina tsvina, asi zvakare inogona kushandiswa pakucheka zvinhu zvakapfava zvakadai sesimbi yakakandwa, aluminium alloy, ndarira uye mhangura, etc. inonyanya kukodzera kucheka pahupamhi uye yakakwirira tembiricha yakaoma kucheka.
