Izinzuzo zokumboza amathuluzi okusika i-carbide

Amathuluzi okusika i-Tungsten carbide angamathuluzi okusika asetshenziswa kakhulu emakethe yemishini, futhi amathuluzi anjalo akhulise kakhulu izinga lokukhiqiza lezinqubo zokusika insimbi, ngaleyo ndlela anciphisa kakhulu izindleko zokukhiqiza izinto zansuku zonke. Izinqubo ezihlukahlukene zokugqoka ezithuthukisiwe nezinto zokugqoka seziyatholakala emakethe.

I-Carbide insert ene-coating inezinzuzo ezinkulu ezinhlanu njengoba ngezansi:

1. I-TiN yegolide engaphezulu inomphumela wokunciphisa ukungqubuzana nokunikeza ukuqashelwa kokuguga

2. Isakhiwo esikhethekile se-Al2O3 isendlalelo sokubeka sinokusebenza okungcono kakhulu kwesithiyo esishisayo, ukuvikela ukusika okomile okunesivinini esikhulu, ukumelana ne-substrate yokufaka ikhono lokuguqulwa kwepulasitiki.

3. Isendlalelo se-TiCN sinokusebenza kokugqokwa kwe-anti-abrasive, okwenza ubuso bangemuva bokufaka bube nokusebenza okuqine kakhulu kokunqanda ukuhuzuka.

4. Ukusebenzisa ubuchwepheshe be-gradient sintering, ukumelana komthelela kanye nokumelana nokugqoka konqenqema lokusika kuyathuthukiswa, ngaleyo ndlela kuthuthukiswe ikhono lokunqanda ukuphulwa konqenqema lokusika.

5. Iqukethe i-carbide ene-crystal structure ekhethekile, ethuthukisa ubulukhuni obubomvu be-matrix ye-tip ye-carbide futhi iqinise ukumelana nokushisa okuphezulu kokufakwayo.

Izigayo ezine-coating zinezinzuzo ezinkulu ezinhlanu njengoba zingezansi:

1.Ukusebenza okuhle kokusebenza nokusika: Amathuluzi okusika ensimbi anamathiselwe ahlanganisa ukusebenza okuhle kakhulu kwezinto eziyisisekelo kanye nokokunamathelayo, okungagcini nje ngokulondoloza ukuqina okuhle namandla aphezulu esisekelo, kodwa futhi anokuqina okuphezulu, ukumelana nokugqokwa okuphezulu. kanye nokumelana okuphansi kokugqoka, i-coefficient of friction. Ngakho-ke, isivinini sokusika sethuluzi elimboziwe singanyuswa izikhathi ezingaphezu kwezingu-2 kunesethuluzi elingagcotshiwe, futhi izinga lokuphakelayo eliphezulu livunyelwe, futhi nempilo yalo nayo isithuthukisiwe.

2.Ukuguquguquka okunamandla: Amathuluzi ahlanganisiwe anokuhlukahluka okubanzi futhi ububanzi bokucubungula bunwetshwa kakhulu. Olunye uhlobo lwethuluzi eliboshwe lingashintsha izinhlobo eziningana zamathuluzi angagqokile.

3.Ukuqina kokunamathela: Impilo yamathuluzi izokhula ngokukhula kogqinsi lwe-coating, kodwa uma ukujiya kwe-coating kufinyelela ekugcwalisweni, impilo yamathuluzi ngeke isakhula kakhulu. Uma ukugqoka kukhulu kakhulu, kulula ukubangela ukuxebuka; lapho ukugqoka kuncane kakhulu, ukumelana nokugqoka kumpofu.

I-4.Regrindability: ukuguqulwa okungalungile kwama-blade ahlanganisiwe, imishini yokugqoka eyinkimbinkimbi, izidingo zenqubo ephezulu, kanye nesikhathi eside sokugqoka.

I-5.Izinto zokugqoka: amathuluzi okusika anezinto ezihlukahlukene zokugqoka anokusebenza okuhlukile kokusika. Isibonelo, lapho usikwa ngesivinini esiphansi, ukunamathela kwe-TiC kunenzuzo: lapho usika ngesivinini esikhulu, i-TiN ifaneleka kakhulu.
