The reason I have choosen the topic ,,Investigation of the effects of the surface quality on the mechanical properties of adhesion” is because there are more and more different kind of adhesive technologies and in opinion it is important to give them more attention at mechanical engineering as well. In my thesis I am going to talk about how different type of surfaces effect on adhesives. I am going to test 3 different type of surfaces for aluminum with my supervisor. The process by which one material attaches to the surfaces of some other substance is known as adhesion. Its use is simple and economical. It gives surface impermeability. It has the advantage of being able to be applied to practically any surface or substance. It is capable of filling in the blanks. It is both insulating and dampening. Strength-to-weight ratios are proportionate to one another
