Kev cuam tshuam ntawm kev hnav khib nyiab ntawm kev coj cwj pwm fretting ntawmti-6al-4v titanium alloystau kawm los ntawm kev tshem cov khib nyiab thiab npaj qhov chaw zoo nkauj los khaws cov khib nyiab tom qab qee lub voj voog ntawm fretting.
Cov txiaj ntsig tau pom tias, tsis zoo li qhov kev nkag siab li niaj zaus, kev tshem tawm cov khib nyiab yuav ua rau muaj kev poob qis hauv kev sib txhuam ntawm kev sib txhuam thiab kev hloov nkhaus ntawm lub cev deformation nrog cov voj voog, qhov siab tshaj plaws ntawm 63% thiab 41%, feem, thiab daim duab micro-cycle yuav hloov raws li. Tom qab qee lub voj voog, lub cim thiab tso tawm ntawm cov khib nyiab pov tseg tau rov sib npaug, thiab kev sib txhuam coefficient thiab lub cev deformation tau rov qab mus rau qib ua ntej tshem tawm cov khib nyiab pov tseg.
Fretting hnav test parameter
Thaum grooved nto kev ntxhib los mos perpendicular mus rau micro kev taw qhia yog npaj rauti-6al-4v titanium alloynto, ib tug loj npaum li cas ntawm cov khoom khib nyiab yog daig nyob rau hauv qhov chaw sib cuag los ntawm grooves, uas ua rau ib tug loj npaum li cas ntawm cov khoom khib nyiab ntawm qhov chaw sib cuag, uas ua rau ib tug loj coefficient ntawm kev sib txhuam thiab lub cev deformation tshaj qhov uas tsis muaj kev ntxhib los mos, nrog ntau tshaj increments. 21% thiab 47% feem.
Scanning electron microscopy (SEM) tom qab sau cov khib nyiab qhia tau hais tias cov khib nyiab yog xoob thiab granular nrog qhov loj me me ntawm 0.2. μ M txog 1.5 μ M thiab feem ntau yog sib sau ua ke.
