I-saw blade egqunyiweyo ifunyanwa ngokugquma umaleko obhityileyo wentsimbi ephikisayo enokumelana nokunxiba kakuhle kumphezulu wentsimbi enesantya esiphezulu (i-HSS) emandla alungileyo kunye nokuqina ngendlela yokubeka umphunga. Njengomqobo we-thermal kunye nesithintelo sekhemikhali, ukugquma kunciphisa ukusasazwa kwe-thermal kunye nokusabela kweekhemikhali phakathi kwe-saw blade kunye ne-workpiece. Inobunzima obuphezulu bomhlaba, ukumelana nokunxiba kakuhle, iipropati ezizinzileyo zeekhemikhali, ukumelana nobushushu kunye nokumelana ne-oxidation, i-coefficient encinci ye-friction kunye ne-thermal conductivity. Iimpawu ezisezantsi, ubomi be-saw blade bunganyuswa ngamaxesha amaninzi xa kuthelekiswa ne-saw blade engabonakaliyo ngexesha lokusika. Ke ngoko, i-saw blade ecandiweyo iye yaba luphawu lwee-saw blades zanamhlanje.

Intsimbi egcweleyo enesantya esiphezulu ibona blade, umbala ngumbala wentsimbi emhlophe, yintsimbi yokusarha ngaphandle kokutyabeka, ukusika iintsimbi eziqhelekileyo ezingezizo, ezifana nobhedu, ialuminiyam njalo njalo.

Nitriding ukutyabeka (omnyama) VAPO nitriding ukutyabeka ubushushu obuphezulu oxidation unyango ubushushu, umbala mnyama mnyama, emva elementi imichiza Fe3O4 iphantsi unyango oluchanekileyo ubushushu obuchanekileyo, umaleko oxide (Fe3O4) yenziwa phezu komhlaba, kunye nobukhulu be oxide umaleko imalunga 5-10 Micron, ukuqina komhlaba malunga 800-900HV, i-friction coefficient: 0.65, olu hlobo isarha blade inobuso obugudileyo elungileyo, nto leyo inceda ukukhulisa isakhono self-lubricating isarha blade, kunye nesenzeko. ukuba i-saw blade ibambelele kwizinto eziphathekayo inokuphetshwa kwinqanaba elithile. Ukusika izinto eziqhelekileyo. Ngenxa yetekhnoloji yokucubungula evuthiweyo kunye nokusebenza kweendleko eziphezulu, yimveliso esetyenziswa kakhulu kwimarike.

Ukwaleka kwe-Titanium nitride (yegolide) I-TIN Emva konyango lwe-PVD nitrogen titanium, ubukhulu becala lesarha yokugquma bumalunga ne-2-4 microns, ukuqina kwayo komphezulu malunga ne-2200-2400HV, i-friction coefficient: 0.55, ubushushu bokusika: 520°C, le yabona i-saw blade inokunyusa kakhulu ixesha lenkonzo ye-saw blade. Ukuze kusetyenziswe ngokupheleleyo iimpawu zayo, isantya sokusika kufuneka sandiswe ukubonisa ixabiso layo. Umsebenzi oyintloko wale ngubo kukwenza i-saw blade ixhathise ukusika. Ukusikwa kwezinto eziqhelekileyo, ukusebenza kwayo okugqwesileyo kunokunyusa ngokufanelekileyo isantya sokusika kunye nokunciphisa ilahleko.

I-Chromium Nitride Coating (I-Super Coating emfutshane) I-CrN Le ngubo ixhathisa ngokukodwa ukunamathela, ukubola kunye ne-oxidation. Ubunzima bokugubungela i-saw blade yi-2-4 microns, ubunzima bomhlaba: 1800HV, ubushushu bokusika bungaphantsi kwe-700 ° C, kunye nombala we-metallic grey. Kunconywa kakhulu ukusika ubhedu kunye ne-titanium, inkqubo yokugqoka ayinayo impembelelo kwindalo. Ilungele ukusika ubhedu, i-aluminiyam kunye nezinye izinto, ezinobuninzi obuphezulu bokugquma kunye nokuqina komphezulu, kunye neyona nto iphantsi yokukhuhla phakathi kwazo zonke iingubo.

I-Titanium aluminiyam ye-nitride yokwambathisa (umbala) I-TIALN Le yinto entsha yolwaleko oluchasene nokunxiba. I-saw blade ephathwe nge-multi-layer ye-PVD yokwambathisa iphumelele i-coefficient ephantsi kakhulu yokukhuhlana. Ubunzima bayo bomhlaba bumalunga ne-3000-3300HV. i-friction coefficient: 0.35, iqondo lokushisa kwe-oxidation: 450 ° C, olu hlobo lwe-saw blade lunokwenza indawo yokusika igudiswe kakhulu, kwaye i-saw blade iyaxhathisa. Kunconywa ukusika izinto eziphathekayo ngesantya esiphezulu sokusika kunye nesantya sokutya kunye namandla okusika angaphantsi kwe-800 N / mm2, njenge-Stainless steel, njl., esetyenziswa phantsi kweemeko zokusebenza ezinzima.

I-Aluminiyam titanium nitride yokwambathisa (ebizwa ngokuba yi-super A coating) I-ALTIN ​​Le yimbumba entsha ye-anti-wear ye-anti-wear coefficient entsha, ubukhulu bolu tyalo yi-2-4 microns, ubunzima bomhlaba: 3500HV, i-coefficient ye-friction: 0.4, ukusika iqondo lobushushu Ngaphantsi kwe-900 ° C, kucetyiswa ukuba kusetyenziswe izinto ezinesantya esiphezulu sokusika kunye nesantya sokutya kunye nokusika amandla okuqina angaphezu kwama-800 N/mm2 (njengensimbi engenasici), kwaye uyisebenzise phantsi kweemeko zokusebenza ezinzima.njengokusika okomileyo. Ngenxa yokuqina kunye nokuzinza okuhle ngokomzimba kwe-aluminium titanium nitride yokwambathisa ngokwayo, i-saw blade ayigugi kwaye ifanelekile ukusika zonke izinto zentsimbi. Ngenxa ye-coefficient ye-friction ephantsi kunye ne-conductivity ephantsi ye-thermal, ifaneleke ngokukodwa ukusika okomileyo ngesantya esiphezulu kunye nokushisa okuphezulu.

I-Titanium Carbonitride Coating (Bronze) I-TICN Olu lutyalo olulungele iimfuno eziqatha zokuchasa ukunxitywa. Kunconywa ukusika izixhobo ezinamandla okuqina ngaphezu kwe-800 N / mm2. Ubunzima bengubo yi-3 microns, i-coefficient of friction: 0.45, ukushisa kwe-oxidation: 875 ° C, kunye nobunzima bomhlaba malunga ne-3300-3500HV. Ayifanelekanga kuphela ukusika isinyithi esinamandla amakhulu njengensimbi engenasici, kodwa ingasetyenziselwa ukusika izinto ezithambileyo ezifana nentsimbi, i-aluminium alloy, ubhedu kunye nobhedu, njl. ifaneleke ngokukodwa ukusika kwisantya esiphezulu kunye nokushisa okuphezulu kwe-cut cut.
