I-PEEK (i-polyetheretherketone) iyinto ehlanganisiwe esebenza kahle kakhulu eyenziwe ngokuhlanganisa i-PEEK resin ngezinto zokuqinisa ezifana ne-carbon fiber, i-glass fiber, kanye ne-ceramics. Izinto ze-PEEK ezinobulukhuni obuphezulu zimelana kakhulu nemihuzuko nokuklwebheka, futhi zifanelekela ukukhiqiza izingxenye nezingxenye ezingagugi ezidinga ukwesekwa okunamandla aphezulu. Ubulukhuni obuphezulu be-PEEK buyenza ikwazi ukugcina isimo sayo ngisho nangemva kokucindezeleka komshini nokusetshenziswa isikhathi eside, okwenza isetshenziswe kabanzi emikhakheni yezindiza, yezimoto, yezokwelapha kanye neminye.
Kwizinto ezihlanganisiwe ze-PEEK polymer, ubulukhuni be-Rockwell bungenye yezinkomba ezibalulekile zokuhlola ukusebenza kwayo. Isimiso sokuhlola ubulukhuni be-Rockwell sisekelwe endleleni yokubeka imbobo, enquma inani lobulukhuni bento ngokulinganisa ukujula kokubeka imbobo okukhiqizwa yi-indenter ethile ecindezela ebusweni bento ngaphansi kwamandla okuhlola athile. Ngaphezu kwalokho, kuyadingeka futhi ukuhlola izakhiwo zayo zomshini ngokuhlola amandla ayo okudonsa, amandla okugoba, amandla okushaya, njll., nokulandela amazinga omhlaba wonke noma kazwelonke njenge-ISO, i-ASTM, njll. ukwenza izivivinyo ezijwayelekile ukuqinisekisa ukuzinza kwekhwalithi nokusebenza kwayo, nokuqinisekisa ukuphepha nokuthembeka kokusetshenziswa kwayo emikhakheni ehlobene.
Imiphumela yokuhlolwa kobulukhuni beRockwell ingabonisa ngqo ikhono lezinto ezihlanganisiwe ze-PEEK polymer ukumelana nokuguqulwa kwepulasitiki. Ubulukhuni beRockwell obuphezulu busho ukuthi izinto zinamandla okuklwebheka nokuguguleka, okubalulekile ekukhiqizeni izingxenye ensimini yezindiza, ukuqinisekisa ukuthi izingxenye zingasebenza ngokuzinzile nangesikhathi eside ezindaweni eziyinkimbinkimbi zemishini kanye nezimo ezimbi kakhulu; uma zisetshenziswa ensimini yezimoto ukukhiqiza izingxenye zenjini kanye nezingxenye zesistimu yokudlulisa, izinto ezihlanganisiwe ze-PEEK ezinobulukhuni obuphezulu zingathuthukisa ngempumelelo impilo yesevisi kanye nokuthembeka kwezingxenye; emkhakheni wezokwelapha, uma zisetshenziselwa ukukhiqiza izinsimbi zokuhlinza noma izifakelo, ubulukhuni obufanele abugcini nje ngokuqinisekisa ukusebenza kokusebenza kwethuluzi, kodwa futhi buhlangabezana nokuhambisana okuhle kwemishini phakathi kwesifakelo nezicubu zomuntu. Ngesikhathi esifanayo, imiphumela yokuhlolwa kobulukhuni beRockwell ingasetshenziswa futhi njengesisekelo esiyinhloko sokulawula ikhwalithi, esetshenziselwa ukuqapha ukuzinza kokusebenza kwezinto ze-PEEK ngesikhathi senqubo yokukhiqiza, kanye nokuthola ngokushesha izinkinga zekhwalithi ezibangelwa izinguquko ezintweni zokusetshenziswa, ubuchwepheshe bokucubungula nezinye izici.
Uma kuhlolwa ubulukhuni beRockwell bezinto ze-PEEK, uhlobo lwe-indenter kanye namandla okuhlola kufanele kukhethwe ngokufanele ngokuya ngezici zezinto kanye nobubanzi bobulukhuni obungaba khona. Izikali ezivame ukusetshenziswa zifaka phakathi i-HRA, i-HRB, i-HRC, i-HRE, i-HRR, i-HRL, i-HRM, njll.
Ngaphambi kokuhlolwa okusemthethweni, qiniseka ukuthi ubuso bokuhlola bezinto ze-PEEK buyisicaba, bubushelelezi, futhi abunawoyela, ungqimba lwe-oxide noma okunye ukungcola ukuqinisekisa ukunemba kwemiphumela yokuhlolwa. Beka isampula ngokuqinile ebhentshini lokusebenza lomhloli wokuqina ukuqinisekisa ukuthi isampula ayinyakazi ngesikhathi sokuhlolwa. Isikhathi ngasinye lapho kwenziwa ukuhlolwa, izinqubo zokusebenza zomhloli wokuqina kumele zilandelwe ngokuqinile, futhi amandla okuhlola kumele asetshenziswe kancane ukuze kugwenywe ukulayisha okuthintekayo. Ngemva kokuba amandla okuhlola ezinzile isikhathi esibekiwe, funda futhi urekhode inani lokuqina kwe-Rockwell elihambisana nokujula kokufakwa. Ukuze uthole idatha emele kakhulu, izilinganiso eziningi zivame ukwenziwa ezindaweni ezahlukene, njengokukhetha amaphuzu okuhlola ama-5 noma ngaphezulu ahlukene, bese imiphumela yokulinganisa ihlaziywa ngokwezibalo ukuze kubalwe amapharamitha afana nenani eliphakathi kanye nokuphambuka okujwayelekile.
