I-YG vs YN Cemented Carbides: Iiyantlukwano eziphambili kwi-Industrial Machining

1. Isikhundla esingundoqo: Umahluko osisiseko phakathi kwe-YG kunye ne-YN

(A) Uqulunqo olutyhilwe nguNomenclature

• Uthotho lwe-YG (WC-Co Carbides): Yakhelwe kwi-tungsten carbide (WC) njengesigaba esinzima kunye ne-cobalt (Co) njenge-binder (umzekelo, i-YG8 iqulethe i-8% Co), eyenzelweukuqina kunye nokusebenza kakuhle kweendleko.
• YN Series (TiC-Based Carbides): Kukho iindidi ezimbini: iTiC-based esulungekileyo (umz., YN10 ene-Ni-Mo binder) okanye i-WC-TiC composite (umz., YN6 ene-Co-Ni binder), elungiselelweubunzima obuphezulu, ukumelana nobushushu, kunye nezicelo ezikhethekileyo zokusingqongileyo.

(B) Isigwebo seSicelo seSicelo sokuqala

• I-YG iyagqwesa kwizinto ezithambileyo kunye neemeko zempembelelo: Ilungele intsimbi etyhidiweyo, iintsimbi ezingezizo i-ferrous (i-aluminiyam, ikopolo), kunye nokusetyenziswa okudinga ukuxhathisa impembelelo njengokugrunjwa komhlaba kunye nokunyathela kuyafa.
• I-YN igxile kwizinto ezinzima kunye neemeko ezingqongileyo: Igqibelele ukugqiba i-carbon steel / insimbi ecinyiweyo, i-high-temperature corrosive environments (ikhemikhali, i-aerospace), kunye nezixhobo ze-elektroniki ezingenamagnetic.

2. Uthelekiso olunzulu: Ukususela ekuBumbeni ukuya kwiNtsebenzo ukuya kwiSicelo

(A) Ukuqulunqwa: IKhowudi yeMichiza yeeBinders kunye neZigaba ezinzima

1. I-YG Series: I-Champion yokuqina kweNkqubo ye-WC-Co ecocekileyo

• Ifomula engundoqo: 85% -94% WC, 6% -15% Co (umz., YG15 nge-15% Co), akukho titanium (Ti), ubuninzi be-13.9-14.8g / cm³ (i-alloy enzima).
• I-Microstructural Advantage: I-Ductility ye-Co inika amandla abalaseleyo e-flexural (YG8 ifikelela kwi-2300MPa). Amanqanaba okutya okuziinkozo (umzekelo, i-YG3X) aphucula ubulukhuni ukuya kwi-92HRA ngokucokisa iinkozo ze-WC, ukulinganisa ukuxhathisa ukunxiba kunye nokuxhathisa ukutshiphuza.

2. Uchungechunge lwe-YN: Ukuphumelela kokuSebenza kwe-TiC-Based Alloys

• I-TiC-Based Alloys (umz., YN10): Ngaphezulu kwe-90% ye-TiC, i-10% ye-Ni-Mo binder, ubuninzi be-5.5-6.0g / cm³ kuphela, ukuqina kwe-92-95HRA, ukugcina isakhono sokusika kwi-1200℃ kunye nokumelana okubalaseleyo kwi-crater wear.
• I-WC-TiC Composite (umz., YN6): I-92% ye-WC elawulayo, i-2% ye-Ni + 6% Co yongeziweyo, idibanisa ukuqina kwe-YG (1800MPa amandla aguquguqukayo) kunye nokuxhatshazwa kwe-YN ye-corrosion ye-medium-load-acid / alkali scenarios.

(B) Iiyantlukwano zeNtsebenzo: Iinguqu eziphambili zokuSebenza ngokuSebenza ngokuSebenza kunye noBomi beSixhobo

1. Ubunzima kunye nokuNxilwa koMgqomo: I-YN ibeka iBenchmark ye-Precision Machining

• I-YN ecocekileyo ye-TiC-based-hardness: 91-95HRA, ukwandisa ubomi besixhobo 3-5 amaxesha xa kuthelekiswa ne-YG xa kucinywa intsimbi (60HRC). I-coefficient ye-friction esezantsi (0.3 vs YG's 0.5) inciphisa umonakalo wobushushu bomsebenzi.

2. Ukuqina kunye nokuchasana kweMpembelelo: I-YG iKhokela ekusikeni okuNgaphakathi

• I-cobalt ye-YG ibonelela ngokuqina kwempembelelo ye-4-8J/cm² (YG20C kwi-6J/cm²), inciphisa umngcipheko wokutshiphuzwa ngama-40% ekusikeni okwethutyana (umzekelo, intsimbi yokusila okanye izikhewu ezikhutshiweyo).
• I-YN ecocekileyo ye-TiC-based ine-toughness ephantsi (1500MPa amandla aguquguqukayo), kodwa i-composite YN15 yandisa amandla aguquguqukayo kwi-2000MPa ngokongeza i-WC kunye ne-Co, ukuhlangabezana neemfuno ezichasene ne-vibration zokunciphisa umthwalo oqhubekayo wokusika.

3. Ukumelana nokushisa kunye nokuzinza kweMichiza: I-YN Pioneers High-Temperature Machining

• Ubunzima obubomvu be-YG: 600-800℃, apho i-Co idibanisa ngokulula ngesinyithi esinentsimbi, ibangela ukwakhiwa kwesixhobo.
• I-YN esulungekileyo ye-TiC-based ukumelana ne-1000-1300℃, ene-Ni-Mo binder exhathisa i-oxidation. Ubudlelwane obuphantsi be-TiC bensimbi buphucula ukusebenza kwe-anti-adhesion nge-60% kwi-machining yensimbi engenasici, efanelekileyo yokusika isantya esiphezulu (isantya somgca ≥200m / min).

(C) Iimeko zeSicelo: “Ukhetho oluNinzi” lweeMfuno zoMatshini eziChanekileyo

• Ukwenziwa koMngundo: Amabakala aphezulu-Co afana neYG20C (20% Co) kwisihloko esibandayo siyafa, simelana > 2000MPa uxinzelelo olucinezelayo kunye ne-5x ehlala ixesha elide kune-HSS molds.
• Geological Drilling: Amazinyo okomba i-YG11C anciphisa ukwaphuka kwempembelelo yamatye ngama-25% ekutsalweni kwerhasi ye-shale, ephucula ukugrumba okusebenzayo nge-15%.

2. Uluhlu lwe-YN: iNkokheli yokuSebenza yokuGqiba iNsimbi kunye neeNdawo eziKhethekileyo

• Ukuchaneka koMatshini weNsimbi ecinyiweyo: Izixhobo zokuguqula i-YN10 zigqiba i-58HRC ephethe insimbi kwi-150m / min, ukufezekisa ubunzima be-Ra0.4μm, ukusondela ukuchaneka kokugaya.
• Izahlulo ezinganyangekiyo kwi-Corrosion kuShishino lweMichiza: Amakhonkco okutywinwa kwe-YN6 abonisa izinga lokubola kwe-0.05mm kuphela / ngonyaka kwi-10% ye-hydrochloric acid, ehlala i-3x ixesha elide kune-YG seals.
• Izixhobo zombane ezingezizo iiMagnetic: I-YN15 i-alloy non-magnetic alloy (i-permeability <1.0001) yezixhobo ze-MRI izixhobo, ukuphepha ukuphazamiseka kwamagnetic ngempazamo echanekileyo <0.001mm.
