Nickel-titanium: Daim ntawv thov thiab kev tsim cov khoom siv hlau ua haujlwm siab

Nickel-titanium alloy feem ntau yog tsim los ntawm ob lub ntsiab lus: nickel thiab titanium, uas cov ntsiab lus nickel yog li 55% thiab cov ntsiab lus titanium yog li 45%. Qhov tseem ceeb tshaj plaws ntawm cov khoom siv nickel-titanium yog nws cov duab nco zoo thiab superelasticity. Ob yam khoom no tshwm sim los ntawm cov khoom siv hloov pauv martensitic.

1. ** Lub cim xeeb zoo ** : Nitinol yog deformed ntawm qhov kub thiab txias, thiab tuaj yeem rov qab los rau nws cov duab qub thaum rhuab mus rau qhov kub thiab txias, uas yog dav siv nyob rau hauv ntau yam khoom nco alloy.

2. ** superelasticity ** : Nitinol alloy tuaj yeem tiv taus qhov loj ntawm deformation, thiab tuaj yeem rov qab mus rau nws cov duab qub tom qab kev ntxhov siab. Cov yam ntxwv no ua rau cov khoom siv nickel-titanium ua tau zoo nyob rau hauv cov ntawv thov uas yuav tsum muaj elasticity siab.

3. ** Corrosion resistance ** : Nitinol alloy qhia tau zoo heev corrosion kuj, tshwj xeeb tshaj yog nyob rau hauv acidic thiab alkaline ib puag ncig, uas ua rau nws muaj broad daim ntawv thov kev cia siab nyob rau hauv lub teb ntawm tshuaj thiab Marine engineering.
