Analysis of wear resistance aviation materials with titanium alloys
(National Aviation University, 2021-12) Al-Rybaye, Hasan Falah Hasan; Аль-Рубайє, Хасан Фалах Хасан
To begin with I want to mention that every element has its own life cycle. No matter if it corresponds to elements made by human or some naturally created parts. Though speaking about details that are created for different movement purposes the lifecycle runs much faster. The reason for that is that such details are under great influence of friction forces and hence wear becomes the reason why their lifecycle is so short. Among the maing negative factors that can damage different details is fretting-corrosion. No matter what are the modern methods of repairing and recovery, but unfortunately all of the details that are under cyclic movement cannot avoid its influence. So the way out is to use such materials and especially alloys that can reduce losses of surface and elongate duration of details operation. In our diploma work we will make a set of tests on the special machine that imitates cyclic movement. For obtaining the best results that are close to reality we chose titanium alloy ВТ-22 in couple with different materials and try to compare our important results. Due to this results we will understand the best and most reliable couple for titanium alloy. It’s obvious that titanium is very reliable element and has very high characteristics. So we will try to find out the best metal alloy among the counter specimens. Our investigations will be very useful for different plants, factories and design offices. We will determine the best couple that corresponds to 2 main parameters: prime cost and durability.
