| Iiplastiki ezilukhuni | Polycarbonate (PC), Polyoxymethylene (POM). | Ubunzima obuphezulu, ukuxhathisa okuqinileyo | I-fine-grained okanye i-ultra-fine-grained WC-Co carbide | Ubume obucokisekileyo buphucula ubunzima kunye nokumelana nokunxiba kwesixhobo, ukwandisa ubomi baso benkonzo ngamaxesha angama-2-3. |
2. Ukukhethwa kweziXhobo zeZixhobo zokuSika izixhobo zeMetal
Imisebenzi yokusika isinyithi ineemfuno ezingqongqo kakhulu ekusebenzeni kweemela ezijikelezayo ze-carbide. Ngokweempawu ezahlukeneyo zetsimbi ezingenayo i-ferrous kunye nesinyithi, amanqaku aphambili ekukhetheni izixhobo zesixhobo zezi zilandelayo:
1
- Iimpawu zeMathiriyeli: Ubulukhuni obuphantsi, kodwa i-ductility elungileyo, kunye nemiphetho eyakhelweyo inokwenzeka ngexesha lokusika
- Izixhobo zesixhobo ezicetyiswayo: Iimela ezingqukuva zeCarbide ezinomphezulu ophathwe yi-TiAlN (Titanium Aluminium Nitride) yokugquma.
- Inkcazelo Eluncedo: Ukwaleka kunciphisa i-coefficient ye-friction phakathi kwesixhobo kunye nesinyithi, kunciphisa imiphetho eyakhelweyo, kwaye iphucula ukuxhathisa ukunxiba kunye nokumelana ne-oxidation yesixhobo.
(2) Iintsimbi zeFrerous (Ukuthatha iCarbon Steel kunye neAlloy Steel njengeMizekeliso).
- Iimpawu zeMathiriyeli: Ubunzima obuphezulu, amandla aphezulu, kunye nenani elikhulu lobushushu kunye namandla okusika ziveliswa ngexesha lokusika
- Izixhobo zesixhobo ezicetyiswayo: I-WC-TiC-Co yochungechunge lwe-carbide equlethe umlinganiselo ophezulu we-tungsten carbide (WC) kunye ne-titanium carbide (TiC).
- Inkcazelo Eluncedo: Inokugcina ubunzima obuhle kwaye inxibe ukuxhathisa kumaqondo aphezulu, igcine ngokuzinzileyo ubukhali bomphetho wokusika, kunye nokuphucula ukusebenza kakuhle kokusika.
3. Ukukhethwa kweziXhobo zeZixhobo zokuSika iPhepha kunye neMathiriyeli yeFayibha
Iphepha kunye nezixhobo zefiber zithambile, kodwa ingxaki yokuphonswa kwefayibha ngesixhobo kusenokwenzeka ukuba yenzeke. Iindlela zokukhetha izixhobo zokusebenza zezi zilandelayo:
| Uhlobo lweMathiriyeli | Izinto eziMeliyo | Iingxaki eziqhelekileyo | Izixhobo zesiXhobo ezicetyiswayo | Iindlela zonyango kunye nezinto eziluncedo |
| Amaphepha aqhelekileyo | Iphepha lokushicilela, iphepha lokubhala, njl | - | I-Medium-hardness carbide | Ukusebenza kakuhle kokusika, kunokusika ifayibha ngokukhawuleza, kwaye inobomi obude benkonzo |
| Izinto zeFayibha eziphezulu | Isikhumba, ilaphu, ilaphu elingalukwanga | Iifayibha kulula ukubhijela isixhobo | I-Carbide enonyango lwesipili esingaphezulu okanye i-self-lubricating coating | Ukunyangwa kwe-Mirror kunciphisa uburhabaxa bomphezulu, kwaye i-self-lubricating coating inciphisa ukukhuhlana, ukuthintela ukubanjiswa kwefayibha kunye nokufezekisa ukusika ngokufanelekileyo. |
4. Ezinye iiNgqwalasela zokuKhetha iZixhobo zokuSebenza
Ukongeza kwizinto eziphathekayo, ezi zinto zilandelayo zifuna ukuqwalaselwa ngokubanzi xa ukhetha izixhobo zokuvelisa izixhobo:
- Ukusika iSixhobo sokuSebenza: Izixhobo zokusika ngesantya esiphezulu zifuna izixhobo ukuba zibe namandla aphezulu kunye nokusebenza kolungelelwaniso oluguqukayo
- IiParameters zeNkqubo yokusika: Ukusika isantya, izinga lokutya, njl., kufuneka lihambelane nokusebenza kwesixhobo sokufezekisa isiphumo esihle sokusika.
- Ixabiso Factor: Kwisiseko sokuhlangabezana neemfuno zokusika, nikela kuqala ekukhetheni izixhobo ezinexabiso eliphezulu lokusebenza ukunciphisa iindleko zemveliso.
Xa ii-carbide ezijikelezayo zisika izinto ezahlukeneyo, ukukhethwa kwezixhobo zokuvelisa izixhobo kuyinkqubo ebanzi yokwenza izigqibo. Kuphela ngokuqonda ngokupheleleyo iimpawu zezixhobo zokusika, ukudibanisa izinto ezifana nezixhobo zokusika, iiparitha zenkqubo, kunye neendleko, kunokuthi kukhethwe izixhobo ezifanelekileyo zesixhobo ukuze kuqinisekiswe ukuba umsebenzi wokusika wenziwa ngokufanelekileyo nangokuzinzileyo, ukudala ixabiso elikhulu kwishishini.
