Kev siv cov titanium thiab titanium alloys nyob rau hauv tsheb yog tsuas yog muab faib ua ob pawg: thawj qeb yog txo cov huab hwm coj ntawm sab hauv combustion engine reciprocating qhov chaw. Cov qeb thib ob yog kom txo tag nrho pawg ntawm lub tsheb.
1. titanium alloy txuas pas nrig automotive txuas pas nrig los ntawm titanium
Cov pas nrig txuas ua los ntawm titanium alloy tuaj yeem txo qhov zoo ntawm lub cav, txhim kho kev siv roj thiab txo cov pa ntim. Piv nrog cov hlau txuas txuas, qhov loj tuaj yeem raug txo los ntawm 15 feem pua -20 feem pua. Cov ntaub ntawv siv rau cov pas nrig txuas feem ntau yog Ti-6al-4v/Ti-10v-2Fe-3Al thiab Ti-4Al -4Mo-Sn-0.5Si.
2. Titanium alloy cav valve thiab valve rooj Valve-caij nplooj ntoos hlav retainer
Kev siv cov titanium alloy los ua lub tsheb cav li qub tsis tuaj yeem txo qhov hnyav thiab ntev kev pab cuam lub neej tab sis kuj txhim kho tsheb kev ntseeg siab thiab txuag roj. Piv nrog steel li qub, qhov loj yog txo los ntawm 30-40 feem pua thiab qhov txwv ceev tau nce 20 feem pua. Lub intake valve siv Ti-6Al-4V, thiab lub valve siv Ti-6Al-2Sn-4Zn-2Mo.
3. Titanium alloys tail ncej caij nplooj ntoos hlav
Titanium thiab titanium alloys muaj qhov elastic modulus uas tsis tshua muaj thiab tsim nyog rau kev ua cov khoom elastic. Nyob rau hauv qhov chaw ntawm tib txoj haujlwm elastic, qhov siab ntawm lub caij nplooj ntoos hlav titanium tsuas yog 40 feem pua ntawm lub caij nplooj ntoos hlav steel, thiab nws qhov hnyav yog txo los ntawm 60 feem pua -70 feem pua. Kev qaug zog zoo heev thiab kev txhim kho corrosion ntawm titanium alloys tuaj yeem ua rau muaj kev pab cuam lub neej ntawm titanium springs. Titanium alloys rau tsheb springs yog Ti-4.5Fe-6.8Mo-1.5Al thiab Ti-13V-11C-3Al.
4. Exhaust yeeb nkab thiab muffler exhausting system los ntawm titanium
Titanium yog siv nyob rau hauv lub tso pa system nyob rau hauv loj npaum li cas. Cov pa hluav taws xob ua los ntawm titanium thiab titanium alloy tuaj yeem txuas ntxiv lub neej kev pab cuam, txhim kho kev ntseeg tau thiab txhim kho cov tsos, thiab tuaj yeem txhim kho kev sib txuas. Piv nrog rau cov hlau, titanium tso qhov system tuaj yeem txo nws qhov hnyav los ntawm 40 feem pua.
Titanium silencer tsuas yog 5-6kg, uas yog 40 feem pua tsawg dua li stainless hlau silencers.
5. Lwm qhov chaw
Ntxiv rau cov khoom teev saum toj no, titanium kuj tseem siv rau hauv cov khoom nram qab no: rocker caj npab, ncua kev kawm ntawv, piston pins, turbocharger rotors, fasteners, lug ceev, tsheb nres brackets, qhov rooj projection kab teeb, Nres caliper pistons, pin ncej bolts, clutch disc, siab phaj, thiab hloov khawm.
