Holat Va prospektlar Of Titanium Va Titanium qotishmalar uchun avtomobillar

It now seems that automobiles have been an indispensable means of transportation in our lives for more than 100 years. Titanium's properties such as light weight and high strength have long been the focus of automakers.

Titanium ishlatilgan avtomobillar uchun ko'p yil davomida hozir, va avtomobillar deyarli barchasi ishlatilgan up bu yil. Biroq, it ning ahamiyati narxi ning narxi o'rtacha avtomobil to foydalanish titan foydalanish bu bo'ladi mavzusi of the kelajak. Avtomobillar (shu jumladan mototsikl va diskont avtomobillar) are an paydo bozori titanium uchun .

Afzalliklari foydalanish titan sifatida a material uchun avtomobil qismlari: yuqori quvvat, past zichligi, moduli of elastiklik haqida yarim o'sha po'latdan 2c past koeffitsient termik kengayish, haqida yarim o'sha yarim o'sha zanglamaydigan po'lat va alyuminiy, magnit bo'lmagan, past issiqlik o'tkazuvchanligi, va ifloslanmaydigan to atrof-muhit atrof-muhit. Qo'shimcha, ning ishlatilishi titan in avtomobil sanoatida katta kamaytirish mumkin og'irligi 2c avtomobilning og'irligi 2c kamayishi uning yoqilg'isi iste'moli, yaxshilanishi samaradorligi avtomobil va kamayish shovqini. Ko'ra ma'lumotlar ko'rsatish uchun o'sha ma'lumotlar ko'rsatiladi har 10% kamaytirish in in in the og'irligi of the car body, you 10% of egzoz chiqindilar, va saqlash 7% of yoqilg'i iste'mol, so shunday avtomobil engil a play a % 22energiya tejash, atrof-muhit himoyasi,," ikkita qushning ta'siri bir tosh bilan. Titanium eng ideal metall uchun erishish vazn yo'qotish.

1 titanium qotishmasi avtomobilda dasturlar

Titanium qotishma avtomatik qismlari asosan% 3a dan ti turbinasi rotor pichoqlari% 2c bilan Ti% 7b% 7b0}% 7d} -4}V alloy va boshqa bog'lovchi rodlar, va va boshqalar. In order to achieve past cost, cost, foydalanish kukun metallurgiya usuli usuli to qo'shish titanium qotishmasi. TiB zarrachalari dispers titanium asosida MMC in Ti{-6%2 7dAl{-4}Sn{-4Zr{{6{6}}Nb% 7b{7}}Mo-0.2Si-0.3C qotishmasi matritsa, va material ishlatilgan to 7d dvigatel valflar.

Bu ning misol namunasi the application of the material as a new titanium-based material for automobile engine valves. In addition to connecting rods and engine valves, the original low-cost titanium qotishma LCB TIMETAL ishlatilgan uchun ishlab chiqarish suspenziya springs uchun birinchi vaqt. So'nggi progress in the development of low-cost titanium alloys for engine valves and exhaust valves. Alohida, titanium qotishmalari uchun mototsikl egzoz tizimlari (jimlikchilar) oshdi, shuning uchun egzoz tizimlari yanada mashhur bo'ldi bilan rivojlanish bilan arzon qotishmalar...

1.1 Valflar

avtomobil valflari dan titanium qotishmalari emas nafaqat kamayadi og'irligi 2c uzaytiradi xizmat muddati uzaytiriladi yuqori ishonchli, lekin shuningdek yonilg'i tejaydi. Egzoz valves talab qilinadi ichiga qo'shimcha issiqlik va aşınma qarshiligi. U S. ishlab chiqaruvchilar foydalanish titanium qotishmalari, egzoz valf lar ko'proq keng tarqalgan, iste'mol valf lar tayyorlangan 1 ti{{-6Al{-4V qotishma, bo'lsa holda egzoz vallar tayyorlangan bo'ladi qilinadi qilinadiof Ti-6Al-2Sn-4Zn{%% 7b5}}Mo qotish. Sinterlangan iste'mol valf lar tomonidan ishlab chiqarilgan Hitachi in Yaponiya uchun ta'minlangan yapon avtomobil sanoati bozoriga etkazib berilgan .

Qanday qilib Foundry in THE AQSh foydalanish uzluksiz to'qimalari usullari ishlab valves, har valve has 1/4 vazn of titanium, va u kutilmoqda kutilmoqda 200 million yangi avtomobillar joylashtirilgan on the potentsial bozor har yilda 2c va u erda a valve almashtirish bozori 80 million.

1.2 Valve O'rindiqlar

Eng ko'p ishlatiladigan titan komponenti in motor transport vositalari va motorli transport vositalari 2c bilan an yillik ishlab chiqarish ko'proq 2 50,{000} birliklari, qaysi umuman ishlab chiqarilgan in Ti{{2{2}}%1 7dAl{-4}V qotish, va shuningdek in Yaponiya in in Ti-5}Al -2Cr-1Fe alloy. Chunki the simple shape and small size% 2c mavjud mexanik qo'shimchalar oson qilish uchun va nisbatan arzon. Do not mutlaqo ehtiyoj maxsus sirt davolash, po'latdan valve o'rindiq o'rni 10 dan 12 gacha kamayishi mumkin.

1.3 Titanium ulash rod

Ulash rod yordamida titanium qotishmasi to kamaytirish ning og'irligi the engine is the eng samarali, mumkin juda yaxshilanishi ishlashi. The connecting rod material is asosan Ti{-6Al{-4}}V, boshqa bunday ti}V, boshqa kabi Ti}%1 7b{2}}}Al{-4Mo, Ti-4}Al-2}Sn-4}Mn, etc. are also under development.

1.4 Crankshaft va boshqa dvigatel qismlar

Ti-5Al-2Cr-Fe alloy crankshafts are being trial produced in Japan, and this curve is not yet practical due need for anti-stick davolash. Boshqa dvigatel qismlari kabi roker qo'llari, valve springs, pastki bolt ulash rod mumkin shuningdek mumkin bo'lishi mumkin ti-6}Al-4V qotishmasi.

Yaponiya's maxsus ishlab chiqilgan oson kesish Ti-3Al-2.5V . alloy krankshaft ishlatilgan ishlatilgan in Honda 280 hp 3.%0-}liter V6NSX turi limous , va bilan temir krankshaft ega bir xil charchoq quvvati, og'irligi kamayishi 30%, dvigatel tezligi bilan bir xil charchoq kuchi 2c 30%, the engine speed speed 700R / ga oshdi. The application of of these research results ko'rsatadi titanium qabul qilingan va kengaytirilgan uchun foydalanish avtomobillarda foydalanish uchun kengaytirilgan.

1.5 Qaytish havo kanal

titanium qotishma nozul %/ qaytish havo quvur yig'ilishi emas korroziyaga sabab oltingugurt xlorid va egzoz gaz chiqindilari, aşınma shkala yo'q 2c hatto ichida payvandlash bo'ladi bo'ladi korroziv, bilan taqqoslash bilan taqqoslash bilan an'anaviy egzoz tizimi materiallari va zanglamaydigan po'lat materiallar va zanglamaydigan po'lat 40% ga kamayishi mumkin 40% to to ning og'irligi kamaytirilishi uchun material va yaxshilangan yoqilg'i iqtisodiyoti, tezlash tezroq tezroq 2c qisqaroq freking masofasi. Titaniumning yuqori narxi 2c Titanium Metallar korporatsiyasi of America (Timet) ishlab chiqilgan a maxsus sirt davolash yoqilgan 1 yordam beradigan avtoulovlarning narxi standartlariga javob beradigan qismlar ishlab chiqarish. Titanium tubing qo'llanilgan yangi Chevrolet Corvette Z06 sedaniga qo'llanildi.

1.6 Suspenziya Buloqlar

Compared to steel springs used in general purpose vehicles, titanium springs offer the advantages of light weight, corrosion resistance, and low shear modulus.Timet was designed to meet the cost and part assembly requirements of automotive suspension spring manufacturers by retaining the excellent properties of aerospace titanium alloy springs at a significantly reduced cost. Initial production quantities were small for the new FSI Lupo geared suspension springs from Volkswagen Europe.Timet and Volkswagen announced in January 2001 the introduction of titanium suspension springs in the FSI Lupo 2001 vehicle, of which a production run of 3,500 is expected.

Bahor ishlangan titandan tayyorlangan kamayish mumkin temir ning og'irligi 70 dan 60 foizgacha. In a tipik O'zbekiston tomonidan ishlab chiqarilgan oila avtomobil of six to besh transport vositalari, og'irligi tejash 9kg dan 13,6kg boshiga transport vositasi uchun 13,6kg bo'lishi mumkin orqali to to'rt suspenziya buloqlari orqali foydalanish mumkin.

titanium 1.7 muffler muffler og'irligi faqat 5 dan 6kg, ancha kam dan kam a zanglamaydigan po'lat muffler, va oddiy dan ishlaydi. The titanium in the Japanese automobile field (the actual demand in 19 99 was 457t) is is asosan muffler, qaysi ular asosan ishlatiladi katta avtomobillar (900cc dan ortiq). Yaponiya's to'rtta asosiy ishlab chiqaruvchilar, shu jumladan Honda va Suzuki, da qabul qilingan titan qotishma suskunatlari mavjud. Titanium asosan ishlatiladigan katta avtomobil suskunatrlari va individual o'rta avtomobillar. It titanium's korroziya qarshiligi, kuch va sirt dizayni, va boshqalar.
