I-PEEK (i-polyetheretherketone) yinto edityanisiweyo esebenza kakhulu eyenziwe ngokudibanisa i-PEEK resin ngezinto zokuqinisa ezifana ne-carbon fiber, i-glass fiber, kunye ne-ceramics. Izinto ze-PEEK ezinobunzima obuphezulu ziyamelana ngakumbi nemikrwelo kunye nokukrala, kwaye zifanelekile ukuvelisa iindawo kunye neendawo ezingagugiyo ezifuna inkxaso enamandla aphezulu. Ubunzima obuphezulu be-PEEK buyenza ikwazi ukugcina imo yayo nasemva koxinzelelo loomatshini kunye nokusetyenziswa ixesha elide, nto leyo eyenza ukuba isetyenziswe kakhulu kwiindawo zeenqwelo moya, iimoto, ezonyango nakwezinye iindawo.
Kwizinto ezidityanisiweyo ze-PEEK polymer, ubulukhuni beRockwell ngomnye wemiqondiso ephambili yokuvavanya ukusebenza kwayo. Umgaqo wovavanyo lobulukhuni beRockwell usekelwe kwindlela yokugoba, emisela ixabiso lobulukhuni bezinto ngokulinganisa ubunzulu bokugoba obuveliswa yi-indenter ethile ecinezela kumphezulu wezinto phantsi kwamandla ovavanyo athile. Ukongeza, kuyimfuneko ukuvavanya iipropati zayo zoomatshini ngokuvavanya amandla ayo okutsalwa, amandla okugoba, amandla okuchaphazeleka, njl.njl., kunye nokulandela imigangatho yamazwe ngamazwe okanye yesizwe efana ne-ISO, i-ASTM, njl.njl. ukwenza uvavanyo olusemgangathweni ukuqinisekisa uzinzo lomgangatho wayo kunye nokusebenza kwayo, kunye nokuqinisekisa ukhuseleko kunye nokuthembeka kokusetyenziswa kwayo kwiindawo ezinxulumene nayo.
Iziphumo zovavanyo lobunzima beRockwell zinokubonisa ngokuthe ngqo amandla ezinto ezidityanisiweyo zePEEK polymer ukumelana nokuguqulwa kweplastiki. Ubunzima obuphezulu beRockwell buthetha ukuba izinto zinokumelana nokukrweleka nokuguguleka okunamandla, okubaluleke kakhulu ekwenzeni iindawo kwindawo yeenqwelo-moya, ukuqinisekisa ukuba iindawo zinokusebenza ngokuzinzileyo nangokuhlala ixesha elide kwiindawo ezintsonkothileyo zoomatshini nakwiimeko ezinzima; xa zisetyenziswa kwintsimi yeemoto ukwenza iindawo zenjini kunye neendawo zenkqubo yokudlulisa, izixhobo ezidityanisiweyo zePEEK ezinobunzima obuphezulu zinokuphucula ubomi benkonzo kunye nokuthembeka kwamalungu; kwicandelo lezonyango, xa zisetyenziselwa ukwenza izixhobo zotyando okanye izinto ezifakelwayo, ubunzima obufanelekileyo abunakuqinisekisa kuphela ukusebenza kwesixhobo, kodwa bukwahlangabezana nokuhambelana okuhle koomatshini phakathi kwe-implant kunye nezicubu zomntu. Kwangaxeshanye, iziphumo zovavanyo lobunzima beRockwell zingasetyenziswa njengesiseko esiphambili solawulo lomgangatho, esisetyenziselwa ukujonga uzinzo lokusebenza kwezinto zePEEK ngexesha lenkqubo yemveliso, kunye nokufumanisa ngokukhawuleza iingxaki zomgangatho ezibangelwa lutshintsho kwizixhobo eziluhlaza, iteknoloji yokucubungula kunye nezinye izinto.
Xa kuvavanywa ubulukhuni beRockwell bezinto zePEEK, uhlobo lwe-indenter kunye namandla ovavanyo kufuneka zikhethwe ngokufanelekileyo ngokweempawu zezinto kunye noluhlu lobunzima obunokwenzeka. Izikali ezisetyenziswa rhoqo ziquka i-HRA, i-HRB, i-HRC, i-HRE, i-HRR, i-HRL, i-HRM, njl.
Ngaphambi kovavanyo olusesikweni, qiniseka ukuba umphezulu wovavanyo lwezinto zePEEK uthe tyaba, ugudile, kwaye awunayo ioyile, umaleko we-oxide okanye ezinye izinto ezingcolileyo ukuqinisekisa ukuchaneka kweziphumo zovavanyo. Beka isampuli ngokuqinileyo kwibhentshi yokusebenzela yomvavanyi wobunzima ukuqinisekisa ukuba isampuli ayishukumi ngexesha lovavanyo. Ngalo lonke ixesha uvavanyo lwenziwa, iinkqubo zokusebenza zomvavanyi wobunzima kufuneka zilandelwe ngokungqongqo, kwaye amandla ovavanyo kufuneka asetyenziswe kancinci ukuze kuthintelwe ukulayisha okunempembelelo. Emva kokuba amandla ovavanyo ezinzisiwe ixesha elichaziweyo, funda kwaye urekhode ixabiso lobunzima beRockwell elihambelana nobunzulu bokutsalwa. Ukuze ufumane idatha emele ngakumbi, imilinganiselo emininzi idla ngokwenziwa kwiindawo ezahlukeneyo, njengokukhetha amanqaku ovavanyo ama-5 okanye ngaphezulu ahlukeneyo, kwaye emva koko iziphumo zokulinganisa zihlalutywa ngokwezibalo ukubala iiparameter ezifana nexabiso eliphakathi kunye nokuphambuka okuqhelekileyo.
