Isifundo sika-Porcelain: Kungani izibhodi ezingaphakamileyo zingafuni kumathuba aphakeme kanye nezilungile

Umkhulu wokupheleka kwe-porcelain (ngokugcwele ama-2.4 amagaramu ngamakhubuthi amashumi amabili anamashumi amabili) okunye nesimo sakho esisodwa sikhona sibiza ukudlula kulo ngokwesibonelo ngamaphepha ase-carbide. Le maphethe ayikho kubona kahle ngokupheleka kwe-porcelain okungu-7 ngaphezulu kwe-Mohs scale. Kuzoba kanjani? Amaphethe ase-carbide ayadlula kahle futhi ayadlala amandla amaningi, ngokusho kweminyaka yadlule ema-Journal ya-Material Science, le ndawo yadlala amandla ayadlala amandla angu-600°F.

Le ukungafanani kahle okukhona kule ndawo kufuneka amaphepha amahle we-diamond core ebhekiswe kuukuthwala kwemithombo ngokucophelela—kufika emfanekisweni wokuchaza ubukhulu bakho bokuphatha ngokuphelele.

Indlela amaphepha amahle we-diamond core ayisebenza ngokuphatha ngokuphelele, nokuzimisa izinkotha ngaphandle kokubhaka

Ukuchaza kwe-40—80 micron diamond grit: ukulandela ukuthwala kwemithombo, ukususa kwesikhwama, nokugcina isikhundla sokugcina

Ukubhakisha kwe-porcelain (ukuphatha kwe-Mohs 6—7) kufuna amaphakathi we-diamond angaphezulu kuka-80 microns ukuze kuvikeke amaphakathi amancane. Amaphepha amahle we-diamond core ayisabela isibonelo sesikhundla sokubhaka phakathi kwezinkambo eziningi zezinkambo ezingaphansi, ekupheleni kwezinkinga zokubhaka ezingu-2 GPa—ukuphatha kwe-porcelain. Le sizinda sokugcina isikhundla sokugcina isilungiselela izinto ezintathu eziphambili:

• Ukuthwala kwemithombo : Izinkambo ze-40—60 micron ziyagcina ukuthwala kwemithombo ngokuphelele ngokuphela kuka-15—20% ngaphezu kwezinye izinkambo ezingaphansi kwe-porcelain (I-Journal ya-Materials Processing, 2023)
• Ukulawula Isishunxu : Amaphakathi amancane ayisusa isikhwama ngokuphelele ngokuphela kuka-50% ngokuphela kwezinkambo ezingaphansi ngokuphela kwezinkambo ezingaphansi
• Ubungena Bokushesha : Ayenza isikhundla sokugcina se-Ra < 3.2 μm ngaphandle kwe-Ra > 6.4 μm ngezinkambo ezingaphansi

Amatheshti okudlula amanzi okudlula amanzi akubonisa ukuthi amaphakathi amancane akunciphisa izintemperetura zokuphuma ngama-120°C, okukhuluma ukungabikwa kwezintemperetura eziningi.

Amaphakathi amancane vs. amaphakathi amakhulu: izilinganiso ezibonakalayo zokugcina umgama wokugcina, ubunzima bezinye, nokuchitha kwezintemperetura

Amatheshti emvelo okulinganisa amaphakathi we-diamond e-60-micron ne-200-micron abonisa izidingo ezingavumelekileyo zokusebenza ekudluleni kwamaphepha:

Amaphakathi we-diamond anamandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla okuphatha amandla......

Izinkomba zokudesign ezingcono ezinokuthintela ukusebenza kwe-fine-grained diamond core bits

Imibuzo Evame Ukubuzwa

Kungani izingcezu ezivamile ze-carbide zingakwazi ukubhora kahle e-porcelain?

Ama-carbide abizwa ngokuthi ama-carbide abonakalayo ayasebenza ngoba i-porcelain inzima futhi iyaphuka, inesiqu sobulukhuni esingaphezu kuka-7 esikalini sikaMohs. Lezi zingcezu zikhiqiza ukushisa ngokweqile okuholela ekuqhekekeni nasekungaqiniseki, okuholela ekulimaleni kwezinto ezibonakalayo.

Iziphi izinzuzo ezinikezwa izingcezu eziyigugu zedayimane?

Ama-diamond core bits anezinhlamvu ezihle anikeza ukususwa kwezinto okulawulwayo, okunciphisa ukushisa nokucindezelwa ngaphansi komugqa wokwephuka kwe-porcelain. Zenza ukubhora okungenawo ama-chip ngokusabalalisa ingcindezi phezu kwezinkulungwane zamadayimane amancane.

Ukwakhiwa kwezikhungo ezingenalutho kukuthuthukisa kanjani ukusebenza kahle kokubhola?

Imiklamo ye-hollow-core eneziteshi zamanzi ezizungezile isusa ngempumelelo imfucumfucu futhi ilawula ukupholisa, inciphise ama-chip emaphethelweni futhi inciphise ukucindezeleka okushisayo ngesikhathi sokubhola.
