Analysis for anodized film blackening of aluminum alloy components

Bacterial adherence to anodized titanium alloy

The aim of this study was to evaluate Staphylococcus sp adhesion to modified surfaces of anodized titanium alloy (Ti-6Al-4V). Surface modification involved generation of fluoride-containing titanium oxide nanotube films. Specimens of Ti-6Al-4V alloy 6-4 ELIgrade 23meets the requirements of ASTM F136 2002A (AMS 2631B class A1) were anodized in a mixture of sulphuric/hydrofluoric acid at 20 V for...

analysis of ruin probability for insurance companies using markov chain

در این پایان نامه نشان داده ایم که چگونه می توان مدل ریسک بیمه ای اسپیرر اندرسون را به کمک زنجیره های مارکوف تعریف کرد. سپس به کمک روش های آنالیز ماتریسی احتمال برشکستگی ، میزان مازاد در هنگام برشکستگی و میزان کسری بودجه در زمان وقوع برشکستگی را محاسبه کرده ایم. هدف ما در این پایان نامه بسیار محاسباتی و کاربردی تر از روش های است که در گذشته برای محاسبه این احتمال ارائه شده است. در ابتدا ما نشا...

Magnetoresistance of Nanowires Electrodeposited into Anodized Aluminum Oxide Nanochannels

Cast Aluminum Alloy for High Temperature Applications

Originally developed by NASA as high performance piston alloys to meet U.S. automotive legislation requiring low exhaust emission, the novel NASA alloys now offer dramatic increase in tensile strength for many other applications at elevated temperatures from 450°F (232°C) to about 750°F (400°C). It is an ideal low cost material for cast automotive components such as pistons, cylinder heads, cyl...

Biocompatibility of a titanium–aluminum nitride film coating on a dental alloy

The purpose of this investigation was to develop a coating technique and to study the characteristics of titanium–aluminum nitride [(Ti,Al)N] films deposited on a base-metal alloy (Wiron88R) substrate. Titanium–aluminum nitride thin films were deposited on the alloy surface using a reactive radiofrequency sputtering method. The electrochemical properties of three specimens with and without coat...
