I-saw blade eboshwe itholakala ngokumboza ungqimba oluncane lwensimbi ephikisayo enokumelana okuhle nokugqokwa endaweni engaphansi yensimbi enesivinini esikhulu (HSS) enamandla amahle kanye nokuqina ngendlela yokubeka umhwamuko. Njengesithiyo esishisayo nesithiyo samakhemikhali, ukunamathela kunciphisa ukusabalalisa okushisayo nokusabela kwamakhemikhali phakathi kwe-saw blade kanye nomsebenzi. Inokuqina okuphezulu kwendawo, ukumelana okuhle kokugqoka, izakhiwo zamakhemikhali ezizinzile, ukumelana nokushisa kanye nokumelana ne-oxidation, i-coefficient encane ye-friction kanye ne-thermal conductivity. Izici ezisezingeni eliphansi, impilo ye-saw blade ingakhuphuka izikhathi eziningana uma iqhathaniswa ne-saw blade engahlanganisiwe ngesikhathi sokusika. Ngakho-ke, i-saw blade eboshwe isibe uphawu lwama-saw blades wesimanje.

Insimbi enesivinini esiphezulu esigcwele i-saw blade, umbala umhlophe wensimbi umbala, i-blade yesaha ngaphandle kokwelashwa okunamathelayo, ukusika izinsimbi ezijwayelekile ezingezona ayoni, njengethusi, i-aluminium nokunye.

I-Nitriding coating (emnyama) I-VAPO nitriding enamathela ukushisa okuphezulu kokwelashwa kwe-oxidation ukushisa, umbala umnyama omnyama, ngemva kokuba isici samakhemikhali i-Fe3O4 sibhekene nokwelashwa okukhethekile okushisa, kwakhiwa ungqimba lwe-oxide (Fe3O4) ngaphezulu, nokuqina ungqimba lwe-oxide lumayelana ne-5-10 Micron, ubulukhuni bobuso bungaba ngu-800-900HV, i-coefficient yokungqubuzana: 0.65, lolu hlobo lwe-saw blade lunokushelela okuhle kwendawo, okusiza ukuthuthukisa ikhono lokuzigcoba le-saw blade, kanye nomcimbi ukuthi i-saw blade inamathele ngento ingagwenywa ngezinga elithile. Okokusika izinto ezijwayelekile. Ngenxa yobuchwepheshe bayo bokucubungula obuvuthiwe kanye nokusebenza kwezindleko eziphezulu, kungumkhiqizo osetshenziswa kakhulu emakethe.

I-Titanium nitride coating (yegolide) TIN Ngemva kokwelashwa kwe-PVD nitrogen titanium, ubukhulu be-saw blade enamathela cishe ama-microns angu-2-4, ukuqina kwawo okungaphezulu kucishe kube ngu-2200-2400HV, i-friction coefficient: 0.55, izinga lokushisa elisikayo: 520°C, le saw i-saw blade ingandisa kakhulu isikhathi senkonzo ye-saw blade. Ukuze usebenzise ngokugcwele izici zayo, isivinini sokusika kufanele senyuswe ukuze sibonise inani laso. Umsebenzi oyinhloko walokhu kunamathela ukwenza i-saw blade imelane kakhulu nokusika. Ngokusikwa kwezinto ezijwayelekile, ukusebenza kwayo okuhle kakhulu kungakhuphula ngokuphumelelayo isivinini sokusika futhi kunciphise ukulahlekelwa.

I-Chromium Nitride Coating (I-Super Coating ifushane) I-CrN Le ngxube imelana ikakhulukazi nokunamathela, ukugqwala kanye ne-oxidation. Ugqinsi lwe-saw blade luyi-2-4 microns, ubulukhuni bobuso: 1800HV, izinga lokushisa lokusika lingaphansi kuka-700 ° C, futhi umbala umpunga wensimbi. Kunconywa kakhulu ukusika ithusi ne-titanium, inqubo yokumboza ayinawo umthelela emvelweni. Ifanele ukusika ithusi, i-aluminiyamu nezinye izinto, ezinobuningi bokunamathela obuphezulu kanye nokuqina kwendawo, kanye nesici esiphansi kunazo zonke phakathi kwazo zonke izigqoko.

I-Titanium aluminium nitride coating (umbala) I-TIALN Lena i-anti-wear coating entsha enezendlalelo eziningi. I-saha blade ephathwe nge-PVD enezingqimba eziningi izuze i-coefficient ephansi kakhulu yokungqubuzana. Ukuqina kwayo ebusweni kumayelana ne-3000-3300HV. i-friction coefficient: 0.35, izinga lokushisa le-oxidation: 450°C, lolu hlobo lwe-saw blade lungenza indawo yokusika ibe bushelelezi kakhulu, futhi i-saw blade imelana kakhulu. Kunconywa ukusika izinto ngesivinini esikhulu sokusika kanye nesivinini sokuphakela futhi amandla okusika adlula ama-800 N/mm2, njengensimbi engagqwali, njll., asetshenziswa ngaphansi kwezimo zokusebenza ezinzima.

I-Aluminium titanium nitride coating (okubizwa ngokuthi i-super A coating) I-ALTIN ​​Lena inhlanganisela entsha ye-multi-layer ephikisana nokugqokwa, ugqinsi lwalokhu kunamathela ngama-microns angu-2-4, ukuqina kobuso: 3500HV, i-friction coefficient: 0.4, the izinga lokushisa lokusika Ngaphansi kuka-900 ° C, kunconywa ukuthi usebenzise izinto ezinejubane eliphezulu lokusika kanye nesivinini sokuphakela futhi usike amandla aqinile angaphezu kuka-800 N/mm2 (njengensimbi engagqwali), futhi uyisebenzise ngaphansi kwezimo zokusebenza ezinzima.njengokusika okomile. Ngenxa yokuqina nokuzinza okuhle ngokomzimba kwe-aluminium titanium nitride enamathela ngokwayo, i-saw blade ayigugi futhi ifanele ukusika zonke izinto zensimbi. Ngenxa ye-coefficient yayo ephansi ye-friction kanye ne-thermal conductivity ephansi, ifaneleka ngokukhethekile ukusika okomile ngesivinini esiphezulu kanye nokushisa okuphezulu.

I-Titanium Carbonitride Coating (I-Bronze) I-TICN Lena i-coating efaneleka kakhulu izidingo zokungagqoki. Kunconyelwe izinto zokusika ezinamandla aqinile angaphezu kuka-800 N/mm2. Ubukhulu be-coating ingama-microns angu-3, ​​i-coefficient of friction: 0.45, izinga lokushisa kwe-oxidation: 875 ° C, nokuqina kobuso cishe ku-3300-3500HV. Akufanelekile kuphela ukusika insimbi enamandla amakhulu njengensimbi engagqwali, kodwa futhi ingasetshenziselwa ukusika izinto ezithambile ezifana nensimbi ekhonjiwe, i-aluminium alloy, ithusi nethusi, njll. ifaneleka ngokukhethekile ukusika ngesivinini esikhulu kanye nokushisa okuphezulu kokusika okumile.
