I-PCD: Ukukhetha Okuhle Kakhulu Kwezinto Zokusebenza Ze-Aluminium Zomshini

Amathuluzi e-Polycrystalline Diamond (PCD) anikeza izinzuzo ezingavamile zomshini wokusebenza we-aluminium, okuhlanganisa isikhathi eside samathuluzi kanye namazinga aphezulu okususwa kwensimbi. Kodwa-ke, izindleko zawo zokuqala zingaba phezulu, okungaholela ekwandeni kwezindleko zokucubungula. Izinto ze-aluminium zanamuhla zishintshe kakhulu, futhi lapho kusetshenziswa ama-alloy e-aluminium asanda kuthuthukiswa—ikakhulukazi izinto ezihlanganisiwe ze-silicon ephezulu—kubalulekile ukukhetha ngokucophelela ibanga lamathuluzi e-PCD kanye namapharamitha ejiyometri afanele ukuze kuthuthukiswe umkhiqizo kanye nekhwalithi yokucubungula. Ngenhlanhla, ngenxa yokuncintisana kwemakethe kanye nentuthuko ezinqubweni zokukhiqiza, izindleko ze Amathuluzi e-PCD sehle ngamaphesenti angaphezu kuka-50, okwenza kube lula ukuzithola.

Izici Eziyinhloko Zamathuluzi E-PCD

Ama-insert e-PCD ahlanganisiwe adalwe ngedayimani elicwebezelayo kanye ne-catalyst ngaphansi kokushisa okuphezulu kanye nengcindezi, okuholela esakhiweni esiyingqayizivele esinamabhuloho axhumanisayo ezinhlayiya zedayimani. Le nqubo idala isakhiwo sesiqhingi se-catalyst, esifana nezinto zedayimani ze-monolithic. Ngokungafani ne-PCBN (Polycrystalline Cubic Boron Nitride), engenazo izinto zokubopha zangempela phakathi kwezinhlayiya ze-CBN, i-PCD inesakhiwo se-coalescent lapho izinhlayiya zedayimani zixhunywa khona ngamabhuloho e-lattice.

Amabanga amathuluzi e-PCD ahlukaniswa ngobukhulu bezinhlayiya zedayimane. Ngokwezindinganiso zemboni, amazinga e-PCD amancane, aphakathi nendawo, kanye nama-coarse ahambisana nobukhulu bezinhlayiya obulinganiselwa ku-2 μm, 10 μm, kanye no-25 μm, ngokulandelana. Amabanga e-PCD amakhulu abonisa amandla amakhulu kanye nokumelana nokuguguleka, okunikeza impilo ende yamathuluzi ngesikhathi somshini onzima. Kodwa-ke, imiphetho yokusika yamathuluzi e-PCD amakhulu ingase ingafinyeleli ukuqeda okubushelelezi okungafinyelelwa ngamathuluzi e-PCD amahle, okuthi, ngenkathi enikeza ikhwalithi ephezulu yendawo, avame ukuguguleka ngokushesha.

Amathuluzi Okusika e-PCD Zilungele ukusetshenziswa njengezinsika zesaha ledayimane, ukubhoboza nokwakha, izicucu zedayimane ezisika unqenqema, izifakelo zokujika nokugaya, kanye nezingcezu zokubhoboza idayimane zokubhoboza imigodi ezintweni ezihlanganisiwe kanye namabhodi wesekethe.

I-Boreas ikhiqiza amathuluzi e-PCD adume ngezakhiwo zawo ezibonakalayo ezivelele kanye nobubanzi bezicelo, konke lokhu ngenkathi igcina isakhiwo samanani esincintisanayo. Uma unesifiso sokuthuthukisa amakhono akho okusebenza, i-Boreas iyindlela yakho ehamba phambili yamathuluzi e-PCD asezingeni eliphezulu anikeza ukusebenza kanye nenani.
